The sound is excellent

Great phone great sound easy to use and the battery doesn't run down even if left of the charger for,days!!!!

The sound is actually a little too loud even when the volume control is turned all the way down.

When I press TALK, instead of a dial tone, I get a loud squeeling sound.

Sound is good, headset comfortable

The phone is still usable at this distance, the sound just breaks up a bit.

On the plus side: great sound, lightweight, excellent battery life

Every person I talk to say they can't hear me even with the volume up and there is a humming sound when I use this phone

Excellent sound, easy to use , good reception, in general very good

/s very well, much better than using my headset on a regular phone, and the sound is clear in spite of some background hum (important for phone meetings where some people are far from their speakerphone - it can get pretty faint).The CT14 also has much better performance if I walk out the room; CT12 would get some funny sounds from distance or walls, and buzzes from the microwave, while the CT14 keeps a constant sound everywhere I go

I was concerned about static but the sound is clear - no worries there!

Good sound and very useful to talk without using your hands nor the speakerphone.

Once of the criteria is clear sound.

Its easy to use, has natural sound, and 300 foot range

I will also add that once I got the one unit to work through the modem, the sound really wasn't very good.

There was also a humming/buzzing sound in the background, probably caused by the audio amplifier being in overdrive

Just recently, I have noticed a bit of static sound when I hear the dial tone, but it goes away when I am actually on a call.

Great quality, excellent sound, zero complaints

The mute setting on the CT10 left you listening to a repetitive beeping sound

great sound

The sound is consistently clear and I have never heard anyone complain that my voice was difficult to hear.

Great sound and mobility.

I tested it myself and found the sound to be worse than my cell phone -- and that's pretty hard to do.

It does everything I needed with a minimum of clutter and with good quality sound.---------4 months later, I agree with my review from last June (2013).

Good sound but the headphone didn't last more than 3

But I wanted really good sound, and this doesn't have it

It has clear sound and reception and an excellent range

Sound is extremely clear and my peeps on the other end of the line say it's a huge improvement over the headset I was using before.

Nice clear quality sound

THIS IS a great phone, for working at home, pretty good clear sound, i like that i can walk around with it, and still the sound is good.....

I'm busy at home and love the ease of doing this n' that while conversing
