Feature:
The freedom of not wearing a belt pack is great. I would always have to adjust my belt when going from a movement such as cruches to a standing position.

Quality:
12 Hours of battery life is a bit exagrated maybe 7 at best

Value:
This was one of the best investments that I have made in the fitness industry thus far. `

Desirability:
It is so light that it does not ware on my ears and is very comfortable

Sound:
Excellent quality on this unit. I teach at four different health clubs and the unit easily plugs in to each sound system.

Ease of Use:
Easy to connected and use with any sound system I have to deal with

Feature:
Mute function on the headset is great for speaking to indivduals during class, and blowing your nose, going breathless, etc.

Quality:
Been good so far, 10-12 sweaty cycling classes per week, at an hour a crack, and no problems for over a year with the one that worked.

Desirability:
It's the best looking wireless aerobics headset you can get.

Sound:
As a group indoor cycling instructor at two different clubs, I've used two of these headset/receiver sets in two different settings. They both have great speaking clarity, never any feedback, and are a dream to wear compared to the belt transmitter mics. However, one of them suffered from terrible intermittant transitory "white noise" that we could not solve no matter what we tried. We ended up going back to a Shure belt transmitter mic at that club. So, one was great, the other had to be retired, so I reduced the rating in this catagory going with an 8. To be honest, I'm not sure it was the headset/receiver's fault, could have been the general room set-up or some weird incompatibility with the other components in the system.

Ease of Use:
Very easy to set-up and use.

Overall:
See the "sound" catagory.

Quality:
we have to play with the "on" button to get it to click on. The headset itself is hard on the head when we are on our backs doing bench presses, etc.

Value:
If it works, it's great. But it tends to be sensitive to breaking.

Desirability:
Looks great. Its so nice to not have to wear a belt and transmitter around the waist.

Sound:
We use it in a busy health club.. The sound is good once you get it to the right setting.

Ease of Use:
Very easy to use, just turn it on and go, once the setting is right.

Support:
They fixed the system quickly when it broke.

Overall:
We bought another (different) wireless set as a back-up because this one is so touchy.

Feature:
amazing how it has everything on the headset... very cool

Quality:
didn't work well at all.. lots of buzz...even after I played with the squelch...I've used lots of different headset mics, and I was bummed that this didn't work so well... maybe mine was defective....sent it back.... also: the volume was not loud at all, even with fully cranked up...

Sound:
lots of buzz

Ease of Use:
easy to use
