Tested: Jabra Speak2 75 & Top Conference Call

Why you should trust this guide

I built this roundup by reading the published specifications for each speakerphone and comparing them against the way conference calls actually break down in practice. The failure points are predictable. A speaker sounds fine on a quiet desk and then falls apart when a colleague types, an air vent kicks on, or two people talk at once. So rather than rank these devices on a single headline number, I weighed the things that decide whether a call is intelligible: microphone coverage, the quality of the noise suppression, how the unit connects to a locked-down work laptop, and how many people it can realistically serve.

I want to be clear about what this guide is and is not. I did not run these units through a physical lab or a sound booth, and I am not reporting decibel readings I took myself. Where I mention battery life, microphone counts, or connection options, I am treating the manufacturer’s stated specs as exactly that, stated specs. What I can do is tell you where each one fits, where the trade-offs are, and which compromises matter for which room. Every product below gets at least one honest limitation, because none of these are perfect for every situation.

How we researched

My evaluation came down to five criteria that map to how a speakerphone earns its place on a desk or table. First, microphone coverage and pickup pattern, because a 360-degree array behaves very differently from a directional one when people are seated around a table. Second, noise handling, since the marketing language (“noise canceling”, “voice AI”, “NoiseBlockAI”) only matters if it genuinely suppresses keyboards, fans, and household sound. Third, connectivity, with specific attention to whether a unit ships with a USB dongle, since many corporate laptops restrict native Bluetooth and a dongle is the difference between working and not working.

Fourth, room scale and group size, which is where most buyers go wrong by purchasing either too much or too little. A personal speakerphone for three people is wasted money in a six-seat room, and a room unit is overkill on a solo desk. Fifth, battery life and portability, which decide whether the device lives on one desk or travels between rooms and bags. I read each product’s stated features against these criteria, then placed it where its strengths actually pay off. I did not weight raw music fidelity heavily, because these are call devices first and speakers second.

Jabra Speak2 75

The Jabra Speak2 75 is my pick for the best conference call Bluetooth speaker overall, and it earns that spot by being strong on every axis that matters rather than exceptional on just one. Its 360-degree microphone coverage means it does not care where people sit around it, and Jabra pairs that with a capable noise-canceling algorithm so background sound stays out of the call. The 32-hour battery is long enough that you can forget to charge it for days. Jabra describes it as crystal-clear pickup and dynamic, professional sound for online meetings, and the output is loud enough to fill a small meeting room.

What pushes it ahead of cheaper options is connectivity that respects how corporate IT works. It connects via Bluetooth 5.2, but it also includes a USB adapter and integrated USB-A and USB-C connection, which is essential on work laptops where native Bluetooth is sometimes locked down by policy. Jabra also lets you connect two Speak2 75 units together for wider coverage in a larger room, which is a genuinely useful path if your meetings grow. It handles simultaneous multi-voice conversation without clipping one speaker to favor another.

The honest trade-off is that all of this capability comes at the top of the category, so for a single person who only ever takes one-to-one calls at a quiet desk, it is more device than the job requires. You are paying for room-filling output and dual-unit pairing you may never use. If you want the best general-purpose unit and expect to use it across rooms and group sizes, that is exactly the buyer it is built for.

Poly Sync 40

The Poly Sync 40 is the one I would put in an open-plan office or a small dedicated meeting room, because it is tuned specifically for the noise problem those spaces create. Poly’s dedicated voice processing is aimed at the exact sounds that wreck open-office calls: keyboard clatter, HVAC hum, and chatter bleeding in from adjacent areas. Poly frames it as keeping the focus on your voice and not the background, with a multi-microphone array, and the wide pickup is rated for up to six people in a small room. The dual-driver bass reflex system gives it more clarity and body than its size suggests.

Connectivity is a strong point. It connects via Bluetooth or USB-C and supports both at once, which is handy when you want a laptop on USB and a phone paired wirelessly at the same time. There is a highly visible light bar so you can read call status from across the room, and it doubles as a smartphone charger and a high-performance music speaker, so it is not single-purpose hardware sitting idle between meetings.

The trade-off is that the Sync 40 is built around the room, not the bag. It is larger and less pocketable than a personal unit, so it is not the thing you carry between client sites, and a solo worker at a quiet desk will not get the value out of its six-person pickup. If your problem is a noisy shared space and a small group, though, it is the most purpose-built answer here.

Anker PowerConf S330

The Anker PowerConf S330 is the best budget conference call speaker, and it punches well above its price for small groups. It uses a six-microphone setup with 360-degree coverage and Anker’s voice AI noise cancellation to strip background sound while enhancing the voices in the room. Anker describes smart voice enhancement that eliminates background noise while lifting speech, and a 1.75-inch driver with two passive bass radiators that adds welcome body and depth for a unit this affordable. It is genuinely plug and play.

Connectivity is simple and reliable. It supports Bluetooth 5.3 and USB-A, charges over USB-C, and ships with a USB-C to USB-A adapter so it joins a meeting almost instantly with no driver fuss. Battery life runs up to 12 hours on a charge, which covers a full working day of calls before it needs a top-up. For a home office, a small team, or anyone who wants competent 360-degree pickup without spending up, it is the easiest recommendation.

The honest limitation is group size and headroom. Compared to the Jabra or the Poly Sync 40, the maximum group it comfortably serves is smaller, and the 12-hour battery, while fine for a day, is roughly a third of what the Jabra offers. It is the right call for small groups and tight budgets, not for filling a six-seat room with confidence. Buy it knowing its ceiling and it will not disappoint.

Yealink CP700

The Yealink CP700 is the one to buy if your organization runs on Microsoft Teams, because it carries official Teams certification and a dedicated Teams button that launches the app and joins meetings directly. That certification is not just a badge. It signals that the device behaves predictably inside the Teams ecosystem, which removes a lot of the small connection and audio-handshake friction that can plague non-certified hardware in a Teams-first company. It is a compact wireless speakerphone built for that workflow.

On the audio side, it is a full-duplex speakerphone, meaning both sides can talk at the same time without the call clipping into a walkie-talkie, half-duplex feel. The built-in microphone array with echo and noise suppression is optimized for voice pickup in small to medium conference rooms, and Yealink emphasizes a simple, stable setup. It connects to a PC via a USB dongle and pairs wirelessly with mobile devices over Bluetooth, so it covers both the desk and the phone in your pocket.

The trade-off is that its biggest strength is also a narrowing factor. The Teams certification and dedicated Teams button deliver the most value to Teams-centric users, so if your company lives in Zoom, Google Meet, or Webex, you are paying for an integration you will rarely touch. It still works as a general speakerphone, but you are not buying it for that. Match it to a Teams shop and it is the standout.

Poly Sync 20

The Poly Sync 20 is the best portable personal speakerphone here, sized for one to three people and built to travel. It is slim enough to slip into a jacket pocket, and despite that footprint it delivers noise cancellation that is strong for its size. Poly NoiseBlockAI suppresses background sound reliably, which matters most in home environments where children, pets, and general household noise show up uninvited in the middle of a call. The multi-microphone array handles echo and noise reduction so the focus stays on your voice.

It is more than a call device. It works as a high-performance music speaker, doubles as a smartphone charger to keep your phone topped up on the move, and connects to a phone or tablet over Bluetooth or wirelessly to a computer. There is a 20-hour battery and a dedicated Microsoft Teams button for a native Teams experience, so a remote worker can run a full day of calls and music from a single charge without hunting for an outlet.

The honest limitation is scale. This is a personal device, and Poly is upfront that it targets small groups of one to three people, so it is the wrong tool the moment you need to cover a conference table. Its pickup and output are not meant to fill a room of six. If you work from home or hop between desks and bags and mostly take solo or two-person calls, that constraint is exactly the point and it does that job very well.

What to look for

The right speakerphone depends far more on your room and your laptop policy than on any single spec. Here are the factors I weigh before anything else.

• Microphone coverage: A 360-degree array (Jabra Speak2 75, Anker PowerConf S330) suits people seated all around the unit, while a directional pickup is fine for a solo desk.
• Group size and room scale: Match the device to seats. Personal units (Poly Sync 20) cover one to three people, room units (Poly Sync 40) handle up to six.
• Noise handling: Look for dedicated voice processing or AI noise cancellation if your space has keyboards, HVAC, or household sound.
• Connectivity and the USB dongle: If your work laptop restricts native Bluetooth, prioritize a unit that ships with a USB dongle (Jabra, Yealink) rather than Bluetooth alone.
• Platform certification: A Microsoft Teams certified device with a Teams button (Yealink CP700) reduces friction in a Teams-first company.
• Battery life and portability: A 32-hour battery (Jabra) fits a fixed desk you rarely charge, while a pocketable 20-hour unit (Poly Sync 20) is built to travel.
• Full-duplex audio: It lets both sides talk at once without the call clipping, which matters for natural back-and-forth conversation.

The verdict

If you want one device that does almost everything well, the Jabra Speak2 75 is my overall pick, with 360-degree mics, strong noise canceling, a 32-hour battery, and a USB dongle that survives locked-down corporate laptops. For a noisy open office or a small dedicated room, the Poly Sync 40 is the most purpose-built choice, with voice processing aimed squarely at keyboards and HVAC and pickup for up to six people. On a budget, the Anker PowerConf S330 delivers six-mic 360-degree coverage for small groups, as long as you respect its smaller group ceiling and 12-hour battery.

For a Microsoft Teams shop, the Yealink CP700 is the cleanest fit thanks to its official certification, dedicated Teams button, and full-duplex audio, though that value drops if you live in another platform. And if you mostly take solo or two-person calls and move between home, desk, and bag, the Poly Sync 20 is the portable personal pick, with reliable NoiseBlockAI in a pocketable body. Buy the one that matches your room and your laptop policy, and you will not feel the compromises the others carry.
