Poly - Sync 40 Smart Speakerphone (Plantronics) - Flexible Work Spaces - Connect to PC/Mac via Combined USB-A/USB-C Cable and Smartphones via Bluetooth - Works with Teams (Certified), Zoom & More

Very good speaker. The only thing I love about this is the stability of bluetooth connection. I have two devices connected to this - TV and Phone and both work flawlessly. Sound quality is good. Design is awesome. I wish I could detach the cable. This is the only minor flaw I see along with the length of the cable.

Caller can hear you well and you can hear them well. Good battery life

I'm going to keep this review simple. I was looking for the conference room sound quality that you would find in almost all tech companies back in the 2010's era. You know that sound I'm talking about. The one with the rich deep voice and exceptional quality. Well this is it! Now that I remember, most of those tech company conference phones were Poly's. The issue was that back then they cost like $1200. Not this one! :). If that sound is what you want then look no further. I also like that it has that subtle mute sound and a nice red led bar that lights up to indicate that mute is on. It's a great product! I did try a few other products and was not happy with them. Jabra speak2 75 was not the sound I was looking for. It is decent but sounded thin. This one is it! buy it!

Audio quality is very good. I like that it can be used plugged in to USB/USB-C, or connected via Bluetooth, so I can use it in conference room setups, with a laptop or tablet/phone. My two complaints: 1. I don't like the bottom plastic. It looks and feels like a rotomolded kayak. It would look nicer if the black or dark grey extended down further instead. (That's a pretty petty complaint considering it is fairly durable.) 2. The cord wraps around the bottom and plug then snaps in to a cut out on the bottom. Because of out this is designed, the cord has to be pulled pretty snug, causing a 90 degree bend where the cord enters the USB plug. This isn't an issue if it remains plugged in most the time and is only transported on occasion, but given this is designed to be a portable speakerphone, the plan from the designers is that the cord will be regularly wrapped and crimped. That is going to cause a failure, which will prevent charging, and create garbage. The only question is how long it will take. My current solution to this problem is to leave the USB plug detached from the adapter, this allows the cord to remain straighter, and slightly loose. While not ideal, the design limits many other options. I may try using velcro. The designers should have placed the holder clip at the end of the long straight edge, rather than the end so the cord didn't bend when secured for transport. Or optionally, made the cord a detachable USB-C so that it could be easily replaced and used with any phone charger.

Love this little but powerful guy! We run monthly meetings where several come together and there is always some side business going on where people might be having a quick conversation. When we were listening just through a laptop and we had these side bar conversation it was terrible, I was constantly doing the 'Shhhhhhh' thing so that the rest of us could hear or so that when speaking to our partners on the other end of the line could hear without having this side conversation being the center of the conversation. Now with this wonderful product; Poly, we do not have these issues any longer. We have the ability to have those quick conversations without it bothering everyone else. I am no longer saying 'shhhhh' as if I were their mother. We can hear better and the extra noises are drowned out. The only thing I would like better would to have a little more volume control as we have one person that has hearing aids and she could use it just a hair bit louder, however, everyone else thinks great of the Poly. Thanks Poly!

I use this for my remote meetings in my home office. It has great speakers, plenty of volume, and the mic has very good pickup. If I ever need a replacement, this is what I'll get again.

This product is not worth the price. In fact it’s not worth even 30$. Please stop advertising this product. The fundamental issue is that audio constantly drops with Mac max M3. Incompatible with MacBook.

I love this device, I work at home and two separate offices, this is a great tool for conducting teams/zoom/video/phone calls. the bluetooth connectivity with my smartphone is great, and it works well plugged in via cable to my laptop as well, my only criticism is that I wish it could get a little louder but this is not a serious problem, for work phone calls the volume output is perfectly useable, I use it for white noise while I sleep/nap too.
