- Reviewed in Canada on May 21, 2025Verified Purchasethese have great voice pick-up and a loud speaker to hear the other side. FYI you can daisy-chain these with ethernet cables and power the first one with POE but you still need a USB cable going to the first one for the computer connection. Compares favourably to Poly Trio for sound quality.
- Reviewed in Canada on November 20, 2024Verified PurchaseWorks great as speaker and microphone for the conference room. Microphone quality is amazing compared to Bluetooth options
- Reviewed in Canada on June 13, 2023Verified PurchaseStruggled with large meetings for years. With a 20 person room we were able to get good coverage with two units. It still sounds like talking on a speaker phone in a large room but voices at every location were able to be picked up without difficulty by remote users in Zoom. Would recommend.
- Reviewed in Canada on September 30, 2024Verified PurchaseGreat speaker. Really good mics. Buttons sync with cascaded/daisy chained units.
However, it doesn't work with MS Teams. The mute button will mute the mic and mute MS Teams. When you un-mute on the device, only the mic un-mutes but MS Teams stays muted. This behaviour is so much worse than if the buttons just didn't work with MS Teams at all.
Anker tech support was unhelpful and had no interest in passing on the info to developers who can fix this via firmware. All they could do was tell you the usual trouble shooting steps and kept trying to warranty replace the speakers. These will be getting returned.

5.0 out of 5 stars Conference Room Woes Solved
Verified PurchaseWe have struggled to find a good solution for our large conference room (seats 45 people) for over 10 years. We have installed multiple complicated systems, some costing as much as $60,000, but none of the systems worked as intended. The main challenge we have experienced is callers on the other end being able to clearly hear the speaker in this conference room. The conference room is challenging because our building is right next to a highway, so there is a lot of background noise that most microphones can¡¯t handle. These speakers work phenomenally, I have 3 linked speakers around the room and the caller can hear the speaker from anywhere in the room as clearly as if they were in the room. The AI noise reduction cuts all the highway noise out completely, and the fact that you can link multiple units together means that EVERYONE in the room can be heard, even if they¡¯re not right next to the microphone. Having the microphone on the table means that our participants don¡¯t need to talk toward the ceiling or anywhere non-natural. I can¡¯t speak highly enough of this product. Thank you Anker for making such high quality products. We plan to use these in every conference room in our company.

5.0 out of 5 stars compact and extendable conference room speaker, pretty cool
Verified PurchaseWe had a really small meeting room. yet a computer speaker is not enough for the meeting requirement.
so, I am tasked to buy a compact speakerphone for our tiny conference room.
look at this simple task, I got tons of choices of inexpensive speakerphones on the market that can achieve the task.
Yet, my boss has to bang his head and come up with this idea of future proof. kept talking about what happened if we later had a bigger conference room. and we had to consider the feedback loop if we bring in another speakerphone.
so, then the simple task becomes much more difficult as I am no sound engineer.
after some consultation with friends of "sound expert", fingers crossed. I am starting to look at speakerphones with link capability. and it is amazingly hard to find.
eventually, I found this in this Anker device from mountains of devices with similar capabilities.
this speakerphone does support linking up to five devices so we can later extend to a 20-person meeting room from our current 5-people one. so we don't have to worry about the feedback loop between devices in the same room.
phew...., mission complete.
after hooking this device up, the sound quality is pretty good. clear and load.
and the sound effect is very soft not unlike other crapy speakers that come with crispy sound effects just to achieve the loud conference effect.
I can totally use this new meeting room as my after-work movie theater now. ;)

5.0 out of 5 stars Inexpensive, portable, shockingly good sound quality
Verified PurchaseMy use case:
I support small businesses with their technology needs. This device is perfect for those budget-conscious organizations. I have tested six inexpensive conference room systems and ten stand-alone speakers. All 3k and blow price range and this line of speakers has had the most positive reaching from my clients.
Speaker sound quality:
Ensuring you size the Anker conference device appropriately. The sound quality is superb. These devices can easily fill the room with sound without maximizing the volume. During my testing, I maxed the volume to check the sound quality. I did not notice any clipping or distortion. When I tested in a 24-person conference room. I did not see the need to install the second device for sound quality.
Mic check:
The mic quality is on par when compared to other conference systems. The microphone can pick up the speaker while filtering out the background noise. This is true for both the small, medium, and large units. Anker's product line is far superior to stand-alone conference speaker/mic devices. In larger rooms using the daisy chain design helps improve sound quality, which is a functionality unique to these types of devices. Again, my clients have raved about the great sound quality of these devices.

1.0 out of 5 stars Not for me
Verified PurchaseI purchased this for use at my hospice office for our virtual meetings so every could hear the staff that are calling in for the meeting. After multiple attempts to get this product to work at our office , I gave up and returned the product. The instructions were not the best and we could not get the product to connect to our phones. I would not recommend.
