Conference Speakerphones: Four Routes Compared

TL;DR: If your complaint is "they can't hear me," don't swap your network first — measure your pickup distance. These four speakerphones are four different routes, not four similar products. Prices and specs are marked as of publication.

• Best for a 1–2 person huddle room or desk calls: Anker PowerConf Speakerphone, 6 microphones in a 360-degree array, official 24-hour call time, Zoom certified, model A3301, about $139.99 (as of publication). Product page
• Lowest-cost way to test the problem: Amazon Basics USB Conference Microphone, LJ-USM-001, single-capsule omnidirectional, 100 dB SNR, about 3.8 stars from 271 ratings (as of publication). Product page
• Portable route: Jabra Speak 510, official 15-hour talk time and 1.5 m microphone pickup range, about $95 for the 2025 edition (as of publication). Product page
• For 14-person rooms: EMEET Luna Plus Kit, 8+1 microphone array, officially rated for 14 people with daisy-chaining to 25, about $99.99 (as of publication). Product page

What a Conference Speakerphone Actually Solves

Let me clear up a common misconception first. When people say "they can't hear me" on a remote call, the cause is usually not the network. It is that the physical ceiling of your pickup chain has been broken by the size of the room.

A typical laptop built-in microphone is designed for a scenario where your mouth stays within about 30 cm of it. Put that laptop in the middle of a six-person table and the person seated farthest away is more than 1.5 m from the mic. The signal decays through air, reverberation stacks on top, and the far end hears a quieter, muddier version of you.

A speakerphone takes a different approach: it arranges multiple microphones in a ring, extending usable pickup radius from tens of centimeters to one or two meters. It does not improve fidelity. It improves coverage.

Across the units I tested, one pattern held up: the real dividing line between desktop speakerphones is not how many microphones a device has, but whether that microphone count matches your room size. A 6-mic unit is comfortable on a 6-person table and strained on a 14-person one, where half the room ends up leaning in. That is not a fidelity problem. It is geometry.

The Four Routes and Their Real Limits

Route 1: Anker PowerConf Speakerphone — the desk workhorse

For a personal desk or a small huddle room, this is the one I found easiest to live with.

Specifications: six microphones arranged in a 360-degree ring, officially rated 24 hours of call time, a 6700 mAh battery, model A3301, driven by a single 1.75-inch full-range driver at 3 W output. Connectivity is Bluetooth 5.0 plus USB-C, no drivers needed. About $139.99, 4.4 stars, 5.8K ratings (as of publication, sold by Amazon directly).

The headline feature is Zoom certification. Zoom's hardware certification program lists personal speakerphones as their own device category, and certification requires third-party lab testing plus Zoom's own testing before a product earns the Zoom Certified badge and a listing on the certified hardware page. If your employer has IT procurement rules, that badge is worth more than any spec number.

Anker also built in PowerIQ output, so you can charge a phone from its USB port at 5V/2.1A.

Real defects:

First, 3 W of output gets thin past 8 people in a room — the far end hears a thinner voice. Amazon's own positioning calls it "Personal Workspaces," which is honest: this was never designed for a 14-person room.

Second, the official page explicitly says to upgrade to the latest firmware via the AnkerWork app before use. That means the out-of-box state is not the best state, and you need an app installed. If your IT environment blocks management software, this unit will underperform its marketing.

Third, the listing contradicts itself on Bluetooth version. The bullet points say Bluetooth 5.0 and the spec block says 5.0, but the Amazon title says Bluetooth 5.3. I checked the product page directly and the spec block reads Bluetooth 5.0 — the 5.3 figure appears only in the title. When a single page disagrees with itself, check the manufacturer's own spec page before buying.

Route 2: Amazon Basics USB Conference Microphone — the cheapest diagnostic

This is Amazon's own-brand unit, easy to skip and still worth trying first on pure logic.

Model LJ-USM-001, single-capsule condenser, omnidirectional pickup, 100 dB audio sensitivity, 100 dB rated signal-to-noise ratio, zero-latency output. Low-profile disc shape, includes a 4.9-foot USB cable. About 3.8 stars from 271 ratings (as of publication).

The defect you must know about: the customer summary on the page includes a note that speaker quality feedback is mixed, with several customers pointing out there is no speaker. That is not a misreading. The official specification says it has a built-in headphone jack for connecting headphones or speakers, and that speakers are not included.

So the Amazon Basics unit is a microphone, not a speakerphone. It sends your voice out; other people's voices still come through your laptop's built-in speakers. That works in a small room, but once two or three people talk at once, the near end hears a mess of overlapping reverberation. Its own official use cases — classrooms, workshops, court reporting — are settings where amplifying output was never the point.

The 3.8-star score says the rest: 47% of ratings are one star. Know what you are buying — a diagnostic tool, not a device that will last years.

Why it still earns a recommendation: it is the cheapest way to test whether your microphone is the actual problem. Spend ten dollars first. If meeting quality improves immediately, the problem was pickup, and upgrading to a real speakerphone is justified. If nothing changed, the issue is probably network or room acoustics, and spending more on hardware is wasted money.

Route 3: Jabra Speak 510 — the portable route

Jabra's tech spec sheet is unusually explicit: omnidirectional microphone, microphone frequency range 150 Hz to 6.5 kHz, pickup range up to 1.5 m, a 50 mm speaker with 250 Hz to 14 kHz response, talk time up to 15 hours, roughly 2 hours to charge, 195.4 g body weight, over 200 days standby with auto power-off, and a 2-year warranty.

About $95, 4.7 stars, 137 ratings for the 2025 edition (as of publication). That is the highest rating of the four, and it is the only one covering both conference-mode and music-mode bandwidth (conference mode runs 250 Hz to 7.5 kHz).

Real defects:

First, Bluetooth 3.0. This number matters. Jabra's official tech spec states Bluetooth 3.0 with A2DP v1.2, Hands Free v1.6, and Headset v1.2. Compare that against 5.0 on the Anker and 5.3 on the EMEET. Three generations of Bluetooth is noticeable in a modern office — higher latency and weaker stability in crowded RF environments. In an office dense with Bluetooth devices, this is the unit most likely to give you trouble.

Second, official in-room coverage is 4 people (Jabra's tech spec sheet states "in-room coverage for up to 4 people"). Some third-party channels say 6; go with the manufacturer's 4. Past four people, it strains.

Third, multiple variants of the same model are sold. UC versions, versions bundled with the Link 370/380 adapter, and versions without an adapter all exist, and the titles are vague about which is which. Confirm whether your specific variant includes the USB Bluetooth adapter before buying.

Route 4: EMEET Luna Plus Kit — the 14-person room route

If you need to cover a long conference table that seats a dozen-plus people, only one of these four was designed for that job.

Official figures: eight built-in omnidirectional microphones plus one extension mic, 5 W output, maximum volume officially raised to 89 dB, and a proprietary DSP algorithm called VoiceIA that the manufacturer says cancels echo and more than 282 types of noise. Two units daisy-chained cover 18 people (a separate official page states 25 — the two numbers come from different pages, so confirm the current rating on the product page before buying). Connectivity covers USB 2.0, Bluetooth 5.3, and an included A350 dongle. About $99.99, a 4.3 to 4.6 star range, thousands of ratings (as of publication).

It is the only one of the four that ships with an extension satellite microphone. The main unit alone is officially rated for 10 people; you need host plus satellite to reach 14.

Real defects:

First, the daisy-chain cable is sold separately. You need two units to use daisy-chaining, and the link cable is not in the box, so it is an extra purchase. Several third-party reviews flag this.

Second, the size does not work on a home desk. It is a tabletop device for a meeting room, not something you drop into a laptop bag.

Third, 89 dB maximum volume still runs out in a very large room. This distinction matters: it means "can cover 14 people," not "14 people in a big space will hear clearly."

Fourth, third-party reviews note that 89 dB may be insufficient for very large rooms and that some device connection methods are restricted.

How to Decide by Room Size and Budget

Here is the decision logic compressed into one table:

On a budget with fewer than four people, the Jabra Speak 510 offers the most value of the four. With corporate compliance requirements, going straight to a Zoom-certified unit makes the Anker the clear answer. Past eight people, do not economize within these four — geometry is not solved by buying a more expensive device. If it needs a satellite mic, add the satellite mic.

Troubleshooting: Three Real Failure Modes

Problem one: the other side still cannot hear you, and you assume the device is broken.

This is the most common case. Omnidirectional pickup has a side effect: it captures everything in the room — air conditioning, a refrigerator, keyboard clatter, a television two rooms away. Noise reduction algorithms suppress some steady-state noise, but keyboard transients are handled far less well.

What I do when I test these is place the unit at the geometric center of the room rather than right in front of me. Sitting too close skews the near-end volume balance. The Anker page's claim about automatically balancing voices at different distances describes exactly this principle.

Problem two: firmware was never updated, so performance is degraded.

The Anker PowerConf official page requires an app-based firmware update before use. Without it, echo cancellation and ambient noise suppression underperform. People conclude the device is bad when they simply skipped a step the manufacturer documented. EMEET has the same class of requirement — the company provides EMEETLINK for firmware upgrades and Bluetooth and standby adjustments.

Problem three: you muted, but nobody was told.

The Anker page carries a specific warning: pressing mute on the device mutes both PowerConf and your conferencing software, but the microphone status icon in the meeting platform does not change. You think you are muted, the interface still shows live input, and people keep talking over you. This bites hardest when you switch between meeting platforms.

Frequently Asked Questions

What is the difference between a speakerphone and a regular USB microphone?

A speakerphone uses 360-degree pickup designed so everyone in a room is heard, usually includes a speaker, and is a meeting-room device. A USB microphone like the Amazon Basics unit is a pickup device designed to capture one voice cleanly, and is usually a microphone alone. The test is simple: if only you ever speak, a USB microphone is enough. If three or more people take turns, you need a speakerphone.

What does Zoom certification actually buy you, and is it worth a premium?

Zoom's hardware certification program treats speakerphones as a distinct category, with third-party lab testing plus Zoom's own testing, and certified products appear on the official certified hardware list. The practical value shows up in two situations: an employer IT department maintains an approved device list, or you want assurance the vendor will maintain compatibility (Zoom requires certified appliances to be recertified at least every two years). For personal use, the premium is hard to justify.

What pickup distance should I expect from a conference speakerphone?

Use manufacturer-stated figures, and note that the four differ in what they claim: the Jabra Speak 510 states a maximum of 1.5 m; Amazon Basics states no specific distance (its official positioning covers classrooms and small groups); the Anker PowerConf gives no single number but documents a 360-degree array with automatic volume balancing across distances; the EMEET Luna Plus is rated at 10 people for the host unit and 14 with the satellite mic. A headcount rating is not a distance rating, and the two are not interchangeable.

Is Bluetooth or USB-C the better connection?

It depends on whether your meeting room has stable physical USB ports. Bluetooth avoids cables and suits mobile work but is exposed to interference and version differences — Bluetooth versions across these four units range from 3.0 to 5.3. USB-C has lower latency and better stability, and both the Anker and the EMEET need no drivers. If you work at the same desk every day, I would lean USB-C.

Final Recommendations

Tight budget and solo calls: start with the Amazon Basics LJ-USM-001 to confirm the diagnosis. Small rooms of two to four: the Jabra Speak 510, after confirming your variant includes the USB adapter. Four to eight people with compliance requirements: the Anker PowerConf, and update the firmware first. Ten people or more: the EMEET Luna Plus Kit, and remember to buy the daisy-chain cable separately.
