... and could not increase the volume where we could comfortably hear it

The choice of chimes is quite limited and could not increase the volume where we could comfortably hear it.  Took it down today as we decided it didn't serve our needs.

I'm not sure if the unit I received was defective, incompatible with my ear size, or if I am just not smart enough to figure out how to use it properly, but neither my wife nor I were able to get any noise cancellation out of it.  We tried all four sets of ear pieces and tried inserting it various ways into our ears, but had no luck.  I will say that when the noise cancellation feature was turned on the sound produced through the unit was excellent.  However, because I was looking for something that would block out ambient noise and needed it for a trip I'm taking this week, I was not satisfied enough to pay $70 for it, so I returned it.

Headset is relatively comfortable, but I was under the impression that you could adjust the volume. The volume is not adjustable, so I have to choose between hearing or freezing in my basement office, as I can't run the heater and hear on the headset. I will likely be purchasing a different headset with adjustable volume. Freezing is not appealing.

Podcasts and music worked fine, but when I answered a call, I could barely hear the caller (yes, my volume was all the way up).

I will be getting a different one.

This unit is very loud even on its lowest setting.  On the lowest setting we could not watch TV at night with the volume turned down, as we could not hear the TV over the unit across the room. After one night, we tried but could not convince ourselves it was even close to quiet (even using ear plugs). Nice and small, moved a fair amount of air and is really loud.

I'm giving this product 3 stars; however, I did return them. We needed the cable to connect a mic system and when we plugged one of these in, we actually got very little sound out of the speakers. Our system has amplified speakers and a way to connect the mic directly to the speaker (which is what we needed to do for a meeting), and when we have done this in the past with other cables we got excellent volume. Unfortunately, we had a cable go bad from the existing system and thought this would be a great solution as it would give us extra in the event we needed them in the future. If the output volume had been better, we would have kept and given a higher rating.

good for those who are hard of hearing or in a noise place, adjustable setting for loudness

System is not as loud as I had expected.  We are continually having to put the volume to max to hear it in the next room over.

The volume is upped a bit. It doesn't work well with videos that are very low.

Volume not as loud as I would have liked.  I guess the price was right.  I am a little hard of hearing and it just doesn't fill the room with sound. I put it in the bedroom and it is just right in a smaller room.

It did not increase the volume to level I want since I am a 60 y.o. person I require higher level of voice during my daily workout.

The sound was so low that I couldn't hear it -- even with a headphone.  I'll probably end up giving it to a friend who has exceptional hearing.

The volume does not go up. Very hard to hear.

I work in a mill-work shop which is a pretty loud place. I did not expect an amazing experience, but thought I would be able to use it in my small work area. When using this I had to have the volume on full blast and could barely hear the music past 7-8 feet from the radio. I guessing have the volume maxed for 2 months caused the speakers to blow.
Stereo may be ok, but definitely not for what I needed it.

Sound is a bit tinny, and the max volume is kind of ridiculous, actually.  Works okay in a small room, but if your room is larger than 10 x 10, you will likely want to look elsewhere

It's ok can't turn it up - it's loud enough to not to understand what people are saying but you can still hear them.

Fine quality but the "protective" volume restrictions were more of a hinderance than a help. Even full volume we couldn't hear enough to discern words while on an airplane.
