They have very good sound quality and music sounds great

The sound quality is good although a little bass-y

Even with the drop in bass response, it still gives excellent audio quality, has a battery life that can almost get you through an entire 8-5 work day on a full charge (listening to music nonstop), has good Bluetooth range, and will last you several years without issue

at first I was putting the headphones too far into my ear and it was drowning out the sound with hollow bass, but now i know better to let it just sit in my ear and the sound quality is amazing

I'm sorry to say that for me, the sound quality was particularly bad, to the point that I'm going to try and return them

I need comfortable, sweat-resistant earphones that deliver an excellent audio quality and last a long time

The sound quality is fantastic and while i didn't intend to spend so much money, i saw they were plantronics and gave them a try

The only thing I don't like about them is you lose some sound quality because they don't seal to your ear

High frequency sound has an uneven, piercing quality, dominating the sound over other frequencies.

These come highly recommended by most reviewers, who comment that the sound quality is very good.

Provide great sound quality while still allowing ambient noise

I'm going back to them because they are the most comfortable and reliable sound/talk quality

The sound quality is good although the volume is a little feeble than I had expected

But over the last last three purchases, the quality of their products has clearly deteriorated

Having said that, the audio quality is pretty good

The sound quality is very good, though as at least one other reviewer mentioned, they do not go very deeply into the ear canal, so they do not isolate sound the way other in-ear headphones do, but this is by design as they are intended for outdoor use where it's important to be able to hear your surroundings.

The big problem I've had with this headset has been initial quality.

The sound quality on these is excellent.

Thank you I like the item.

Super comfy and durable (I'm not easy on things)
