Includes which one is actually built for voice calls, and which four are music boxes with a microphone bolted on. - Author: Frederick Cameron - Tags: Speakers, Audio, Bluetooth Speakers The best loud bluetooth speaker for phone calls is the OHAYO X10 Max, because 35W of claimed output and an 18-month warranty arrive in a body weighing 0.99 lb. If calls are the actual job rather than a side benefit, the Jabra Speak 510 is the better buy: it's the only pick in this set whose listing is written around meetings. Here's the honest framing. This is a price ladder as much as a spec ladder, and each rung buys something different. In this guide 1.

The first was a missing water rating. A portable speaker with no published IP figure tells you the maker didn't want to commit to one. Four of the six survivors publish a rating, and two of those are IPX7. The second was a missing warranty. This is the fastest sorting tool in the category, because it costs the brand real money and nobody publishes it lightly. Every pick here states something: 24 months on the Ortizan, 18 months each on the OHAYO and the Anker, 12 on the BolaButty, two years from Jabra, and a 30-day return plus 180 days of support on the buwy clip. The third was a listing that lists nothing. Several candidates published a wattage number and stopped. No weight, no dimensions, no model number. You can't compare a product against five others when there's only one figure to compare. What survived is a set that spans a lot of ground: - Two speakers at IPX7, one at IPX5, one claiming IP6 dust and water resistance - One purpose-built conference speakerphone with a 2025 release date - One clip-on wearable weighing a claimed 64.4 g - Published output claims from 12W up to 35W - Warranty terms from 12 months to 24 Only the Jabra shows more than one seller. Every other pick in this set has a single seller on its listing. ## Does a loud speaker make a good speakerphone? Not automatically, and this is where most shopping for the best loud bluetooth speaker for phone calls goes wrong. Volume and voice clarity are different engineering problems. A speaker built for music pushes bass. Bass sits below the frequency range where speech intelligibility lives, so a bass-heavy speaker can be very loud and still make a caller sound muddy. The microphone matters more than the driver. On a call, your voice travels through the speaker's mic array, and a single omnidirectional mic in a cylindrical body picks up the room as readily as it picks up you. Look at what these listings actually commit to. The Jabra Speak 510 listing talks about crystal-clear audio for calls and meetings and connecting to a desk phone or softphone. That's a speakerphone description. The Ortizan mentions a built-in microphone for call time. The buwy clip claims an ENC mic with intelligent noise reduction. The other three describe music, bass and light shows, and say nothing about voice pickup at all. So treat the call angle as your own judgment call, not a promise from any listing here. If calls are occasional, a loud speaker with a mic is fine. If calls are the reason you're buying, buy the product whose listing was written for calls. ## 1\. OHAYO Portable Bluetooth Speaker Wireless — Best overall **The highest published output in this set, in a body that weighs under a pound and carries an 18-month warranty.** [![Black cylindrical OHAYO X10 Max speaker with mesh grille — the 35W claim sits in a 7.28-inch body weighing 0.99 lb.](https://m.media-amazon.com/images/I/41YwbGCf1pL._SL500_.jpg)](https://www.amazon.com/dp/B0DRRQZ8QX?tag=cowonhq-20) **Best for:** someone who wants the loudest published output in a one-hand body **Skip it if:** voice calls are the main job Nothing else here claims 35W. The next-highest number in this set is the Ortizan's 24W, and the gap of 11W is the widest single-spec separation across all six picks. OHAYO's listing credits that to a rebuilt bass section and a new tweeter, and says the result is clearer bass at maximum volume. That's the manufacturer's account of it, not a measurement. What makes the number usable is the packaging. The X10 Max measures 7.28 x 2.95 x 2.95 in and weighs 0.99 lb. That's a cylinder you can hold in one hand, and it's lighter than the Ortizan by 0.16 lb despite the bigger output claim. The listing states 24 hours of playtime, TWS pairing for a second unit, IPX7 water protection, and lossless playback over USB audio. The 18-month warranty is longer than the BolaButty's 12 and shorter than the Ortizan's 24\. Here's the trade-off. It sells more slowly than the Anker, the BolaButty and the Ortizan in this category, and the listing never once mentions the microphone or call handling. **Pros:** - Highest published output claim in the set at 35W - Under a pound at 0.99 lb - IPX7 rating, matching the best here - 18-month warranty - TWS pairing for a stereo pair **Cons:** - Listing says nothing about the microphone or call quality - Premium price position without a stated call feature - Slowest-moving of the four picks with a sales position - Only one seller lists it [Check Price on Amazon](https://www.amazon.com/dp/B0DRRQZ8QX?tag=cowonhq-20) ## 2\. Jabra Speak 510 (2025 Edition) Portable USB Bluetooth — Best premium **The only pick in this set designed as a speakerphone rather than a music speaker with a mic added.** [![Flat black disc-shaped Jabra Speak 510 conference speaker — a 1.3-inch-tall puck built for meetings, not music.](https://m.media-amazon.com/images/I/413BTmTk1LL._SL500_.jpg)](https://www.amazon.com/dp/B0FC3XV5DK?tag=cowonhq-20) **Best for:** anyone whose speaker spends most of its life on conference calls **Skip it if:** you want outdoor music volume Every feature line on this listing is about meetings. Jabra describes clear audio for calls, setup in seconds, and connection over Bluetooth or USB to a laptop, desk phone, mobile or softphone. That USB option is unique in this set. It also means the speaker can act as a wired audio device on a computer, which no cylinder here can do. The shape tells you the purpose. At 1.3 x 4.72 x 4.72 in, it's a flat puck that sits in the middle of a table, not a tube you stand on a shelf. It's the lightest full-size pick at 6.89 oz. The 2025 release date makes it the newest product here, and the two-year manufacturer warranty ties the Ortizan for the longest term in the set. Now the honest part. This is the most expensive pick here and Jabra publishes no wattage figure at all, so you cannot compare its loudness against the 35W or 24W claims on paper. It carries no water rating either, while four of the other five do. Buy it for voice, not for a patio. **Pros:** - Only pick with call and meeting use in its published description - USB and Bluetooth connection both listed - Two-year manufacturer warranty, joint longest here - Lightest of the non-clip picks at 6.89 oz - Newest product in the set, released 2025 **Cons:** - No published wattage, so loudness can't be compared - No water or dust rating listed - Most expensive pick in this set - Flat puck shape is awkward to pack in a bag [Check Price on Amazon](https://www.amazon.com/dp/B0FC3XV5DK?tag=cowonhq-20) ## 3\. Ortizan X10 Portable Bluetooth Speaker — Runner-up **The longest battery claim and the joint-longest warranty, with a microphone the listing actually acknowledges.** [![Black Ortizan X10 speaker with RGB ring lighting — 24W across two drivers with a stated 30-hour runtime.](https://m.media-amazon.com/images/I/51V78cIVN9L._SL500_.jpg)](https://www.amazon.com/dp/B08FDPW8KR?tag=cowonhq-20) **Best for:** long outdoor sessions where recharging is awkward **Skip it if:** you need the lightest option Two numbers put this speaker in second place on paper. The listing claims 30 hours of playtime, which is six hours more than the 24-hour claims on the OHAYO, the Anker and the BolaButty, and Ortizan pegs that figure to around 65dB rather than leaving it unqualified. The warranty runs 24 months, matching Jabra and beating everything else here. Output is stated as 24W from two 12W drivers with two passive radiators, plus a digital signal processor. Bluetooth 5.3 is the newest version named on any of these listings, with a claimed 66-foot range. The IPX7 rating covers full immersion at 3 ft for about 30 minutes according to Ortizan, and there's an RGB light ring with theme options. Critically, this is one of only two picks whose listing mentions a built-in microphone for calls. That earns it a place in any shortlist for the best loud bluetooth speaker for phone calls. The catch is bulk. At 1.15 lb it's the heaviest pick here, and 6.69 x 3.11 x 3.11 in makes it fatter than the OHAYO while claiming 11W less output. **Pros:** - 30-hour playtime claim, longest in the set - 24-month warranty, joint longest here - Built-in microphone named for call time - IPX7 rating with a stated immersion depth - Bluetooth 5.3, newest version listed here **Cons:** - Heaviest pick at 1.15 lb - 24W claim trails the OHAYO by 11W - RGB lighting is dead weight for desk use - Only one seller lists it [Check Price on Amazon](https://www.amazon.com/dp/B08FDPW8KR?tag=cowonhq-20) ## 4\. Anker soundcore 2 Portable Bluetooth Speaker — Best minimal setup **No lights, no gimmicks, a published 12W and the fastest-selling speaker in this set.** [![Compact black Anker soundcore 2 with rounded corners — a 6.5-inch slab at 0.91 lb with no light ring.](https://m.media-amazon.com/images/I/31i+QGiO6sL._SL500_.jpg)](https://www.amazon.com/dp/B01MTB55WH?tag=cowonhq-20) **Best for:** a desk or nightstand speaker with no lights and no fuss **Skip it if:** you want the biggest published wattage This is the one buyers choose most often here, and the appeal isn't the specification sheet. It's the shape of the product. The soundcore 2 measures 6.5 x 1.77 x 2.13 in, which is the slimmest profile of any full-size pick, and weighs 0.91 lb. It's a slab, not a tube, so it doesn't roll off a nightstand. Anker publishes 12W as an actual size specification rather than a marketing bullet, which is worth noting because it's the only pick here where output appears as a stated spec field. The listing describes dual neodymium drivers, a 5,200mAh battery, a 24-hour runtime claim, BassUp processing and a patented spiral bass port. IPX7 covers splashes, waves and water vapour. The warranty runs 18 months. There's no light show and no TWS mention. For a bedside or desk speaker, that's the point. The honest limitation is loudness. 12W is the lowest published figure in this set, a third of the OHAYO's claim. This model also dates from 2017, making it the oldest product here by eight years, and the listing says nothing about calls or a mic. **Pros:** - Slimmest profile at 1.77 in deep - 12W published as a specification, not a claim - IPX7 rating - 18-month warranty - No lights to disable **Cons:** - Lowest published output in the set at 12W - Released in 2017, oldest pick here - No microphone or call handling mentioned - No TWS pairing listed [Check Price on Amazon](https://www.amazon.com/dp/B01MTB55WH?tag=cowonhq-20) ## 5\. BolaButty Bluetooth Speaker, 20W HD Sound — Best for pros **A 20W claim and a beat-synced light show at the second-cheapest position in this set.** [![Black BolaButty speaker with colour light band — 20W claim in the lightest full-size body at 0.88 lb.](https://m.media-amazon.com/images/I/415vc83DVXL._SL500_.jpg)](https://www.amazon.com/dp/B0BRKPVZB4?tag=cowonhq-20) **Best for:** party use where the light show matters as much as the sound **Skip it if:** the speaker will get properly soaked BolaButty's play is volume-per-dollar plus lighting. The listing claims 20W from two drivers, which lands above the Anker's 12W and below the Ortizan's 24W, and it does that from the second-cheapest position here. At 0.88 lb it's the lightest of the five full-size speakers. The multi-colour light effects sync to the beat and can be customised, and BolaButty publishes something the other light-equipped pick doesn't: the conditions behind the battery claim. Up to 24 hours at 50% volume with the lights off. That's a rare piece of honesty in a listing, and it tells you the lights cost you runtime. Bluetooth 5 handles the connection. Dimensions are 2.81 x 7.87 x 2.76 in, making it the longest body in the set. Two things hold it back. The IPX5 rating covers splashes but not immersion, so it's a step behind the IPX7 on the OHAYO, Ortizan and Anker. The 12-month warranty is the shortest published term here, half the Ortizan's. Calls go unmentioned entirely. **Pros:** - 20W claim from a low price position - Lightest full-size pick at 0.88 lb - Battery claim published with its test conditions - Customisable beat-synced lighting **Cons:** - IPX5 only, no immersion protection - Shortest warranty in the set at 12 months - No microphone or call feature listed - Longest body here at 7.87 in [Check Price on Amazon](https://www.amazon.com/dp/B0BRKPVZB4?tag=cowonhq-20) ## 6\. buwy Wearable Bluetooth Speaker — Best budget pick **A clip-on speaker with a stated ENC mic for hands-free calls, at the cheapest position here.** [![Small black buwy clip-on speaker with magnetic mount — a claimed 64.4 g wearable with an ENC mic.](https://m.media-amazon.com/images/I/41w5WPI7EPL._SL500_.jpg)](https://www.amazon.com/dp/B0GYCX7X5Z?tag=cowonhq-20) **Best for:** hands-free audio clipped to a jacket or a bike **Skip it if:** you want room-filling volume This isn't competing with the other five on sound. It's a different product category solving a different problem. The J19 clips to clothing, a strap or a bike, using what buwy describes as a heavy-duty clip with five times the strength of a standard one, plus a magnetic attachment. Two claims matter for the call use case. The listing names an ENC mic with intelligent noise reduction for hands-free calls in noisy environments, making this one of only two picks that commits to anything about voice. And the claimed 64.4 g weight means you'll forget it's clipped on. The battery is stated as 600mAh, which is a fraction of the Anker's 5,200mAh, and buwy claims IP6 dust and water resistance against site dust, sand and sweat. Support terms are 30 days for returns and 180 days of after-sales help. The gaps are real. This is the cheapest pick and the only one with no published output figure and no weight in the specification fields. The listed dimensions are 1 x 1 x 1 in, which is clearly a placeholder rather than a measurement, so you're buying without knowing the actual size. **Pros:** - Only wearable clip-on design in the set - ENC mic named for hands-free calls - Claimed 64.4 g body weight - Cheapest pick here - Magnetic plus clip dual mounting **Cons:** - No published wattage or driver count - 600mAh battery, smallest capacity here - Listed dimensions are a placeholder, not real - Single driver won't fill a room [Check Price on Amazon](https://www.amazon.com/dp/B0GYCX7X5Z?tag=cowonhq-20) ## What each price step actually buys here The ladder in this set is unusually clean, and it isn't a straight line from cheap to loud. 1. **At the bottom**, the buwy clip and the BolaButty. You get a working speaker and one distinguishing trick: wearability on the clip, lighting on the BolaButty. What you give up is published detail. Neither publishes a warranty longer than 12 months. 2. **In the middle**, the Ortizan and the Anker. This is where warranties stretch to 18 and 24 months, where IPX7 replaces IPX5, and where battery claims get qualified with a volume figure. The 30-hour claim on the Ortizan lives here, not at the top. 3. **At the top**, the OHAYO and the Jabra. Two completely different products at similar positions. The OHAYO buys you the biggest output claim in the set at 35W. The Jabra buys you a design purpose, and gives up the wattage figure and the water rating to do it. The pattern worth noticing: more money did not buy more watts across this whole set. The most expensive pick publishes no wattage at all, and the second-cheapest publishes 20W. What money buys reliably here is warranty length and water protection. ## Wattage, weight and water ratings side by side Line up the three comparable figures and the field sorts itself. **Published output, highest to lowest:** OHAYO 35W, Ortizan 24W, BolaButty 20W, Anker 12W. The Jabra and the buwy publish nothing. **Weight, lightest to heaviest:** buwy at a claimed 64.4 g, Jabra at 6.89 oz, BolaButty at 0.88 lb, Anker at 0.91 lb, OHAYO at 0.99 lb, Ortizan at 1.15 lb. The spread between the lightest and heaviest full-size speaker is 0.27 lb, which is small enough that weight shouldn't decide your pick unless you're backpacking. **Water protection:** IPX7 on the OHAYO, Ortizan and Anker. IPX5 on the BolaButty. IP6 claimed on the buwy. Nothing published on the Jabra. Here's what that reveals. Only one product in this set sits at the top of the wattage table and the water table simultaneously, and that's the OHAYO. Only one has zero entries in either table, and that's the Jabra. Those two facts define the choice at the top of this ranking. You're picking between the loudest specified speaker and the only genuine speakerphone. ## Which pick wins for your situation? Thresholds, not preferences. Use these to flip the recommendation. - **If calls make up more than half your usage**, buy the Jabra Speak 510\. Its listing is the only one written around meetings, and USB connection means it works as a wired computer audio device too. - **If the speaker will go in or near water**, restrict yourself to the three IPX7 picks. The BolaButty's IPX5 handles splashes only. - **If a session runs past 24 hours between charges**, the Ortizan's 30-hour claim is the only one that covers you, and it's stated at around 65dB. - **If your hands need to be free while you move**, the buwy clip is the only option here. Nothing else attaches to you. - **If you want lights**, it's the Ortizan or the BolaButty. Neither the OHAYO, the Anker nor the Jabra mentions any. - **If your speaker lives on a nightstand**, the Anker's 1.77-inch depth and total lack of lighting suit that better than any cylinder. - **If you want the biggest number on the box**, the OHAYO's 35W claim is 11W ahead of anything else here. Most shoppers miss the last one on this list: if you want long warranty coverage above all, the Ortizan and the Jabra both publish 24 months, and everything else here publishes less. ## The verdict The OHAYO X10 Max wins this set on the strength of the specifications it actually publishes. 35W is the highest output claim by a margin of 11W, it delivers that in a 0.99 lb body with IPX7 protection and an 18-month warranty, and it does so without the light ring that pushes the Ortizan and the BolaButty into party-speaker territory. For a single speaker that plays loud, survives weather and handles the occasional call, it's the strongest paper case here. Two conditions flip that. The first is call volume. If your speaker's main job is conference calls rather than music, buy the Jabra Speak 510: it's the only pick in this set whose published description addresses meetings, it connects over USB as well as Bluetooth, and it carries a two-year warranty. The trade you make is a missing wattage figure and no water rating at all. The second is runtime. If you're going past 24 hours between charges, the Ortizan X10's 30-hour claim is the only one in this set that covers you, and Ortizan qualifies it at around 65dB. It also names a built-in microphone, which the OHAYO listing never does. You pay for that with 0.16 lb of extra weight and 11W less claimed output. ## FAQ ### Is a loud bluetooth speaker worth buying for calls? A loud Bluetooth speaker is worth buying for calls only if calls are a secondary use. Music speakers push bass, which sits below the frequencies that carry speech, and their microphones are usually a single element in a cylinder. Two picks here name a mic: the Ortizan and the buwy clip. The Jabra is the only one built for meetings. ### Which pick offers the best value in this set? Best value in this set goes to the BolaButty. It publishes a 20W output claim from the second-cheapest position, weighs 0.88 lb, and states its battery claim honestly at up to 24 hours with 50% volume and lights off. The compromises are real though: IPX5 instead of IPX7, and a 12-month warranty that's the shortest here. ### What does an IPX7 rating actually protect against? An IPX7 rating actually protects against full immersion, not just splashing. Ortizan states its X10 can go 3 ft deep for about 30 minutes. Three picks here carry IPX7: the OHAYO, the Ortizan and the Anker. The BolaButty's IPX5 covers water jets and splashes only. The Jabra publishes no water rating at all. ### OHAYO X10 Max or Jabra Speak 510: which should I buy? Choose between the OHAYO X10 Max and the Jabra Speak 510 on primary use. The OHAYO claims 35W with IPX7 protection and an 18-month warranty, so it wins for music and outdoor volume. The Jabra publishes no wattage but connects over USB, carries a two-year warranty and describes itself for meetings. Calls first means Jabra. ### What mistake do people make shopping for the best loud bluetooth speaker for phone calls? The commonest mistake shopping for the best loud bluetooth speaker for phone calls is treating wattage as a proxy for call clarity. It isn't. Wattage describes music output. Read the listing for microphone details instead. Four of these six picks say nothing whatsoever about their mic, and that silence is the answer. Start by deciding whether this speaker is a music device or a call device, because the two winners here answer different questions. If it's music with occasional calls, the OHAYO X10 Max is the default: nothing else in this set publishes a bigger output claim, and 0.99 lb with IPX7 covers most places you'd take it. If it's calls with occasional music, don't fight the data. The Jabra Speak 510 is the only product here whose maker put meetings in writing, and a two-year warranty on a 2025 release is the strongest support commitment in the group. *Last updated: September 7, 2026\.
