1.0 out of 5 stars Very, very disappointing Nov. 14 2011
By Luc
Let me say, first off, these headphones 'could' be great. The sound that the listener receives is top-notch with deep bass, the range is sufficient for our home (I haven't actually tested beyond 20-30 feet, but I have no need to wander any further afield), they are very comfortable, and the ability to recharge is awesome. No mucking around with batteries or cables.
However, I can NOT recommend this product. Sony has designed an ON/OFF switch that engages when the listener places the phones on their head, and disengages when the unit is removed (to save battery life when not cradled). This feature randomly engages and disengages while wearing the set, resulting in frequent and annoying clicks and pops in the listener's ear (and interruption to the audio stream). I've studied the unit and the mechanism that engages the audio feed is surprisingly flimsy and poorly engineered. Without moving or any noticeable cause from myself, the set will (POP! CRACK!!) repeatedly trip the power toggle frequently, resulting in much annoyance and frustration.
These phones, when they work, are awesome. However, they don't work in a fashion that myself or my family find acceptable (my daughter has given up on using them altogether). Very poorly designed and I'm extremely disappointed that I spent over $70 for a product that's basically unusable.
Also disappointed that, unknown to myself, Amazon does NOT accept refund or exchange. My only recourse is to contact Sony and pursue warranty repair. I'll chalk this up to a mistake made and I won't purchase electronics from Amazon in the future.

4.0 out of 5 stars Nice April 3 2012
Verified Purchase
For the price, I really like these headphones.

When i first set them up i really noticed the "Airy" sound but after ensuring that the volume on my input device and the headphones were adjusted to an optimal level the sound is almost non-existant.

The battery life really depends on the how loud you are listening to your input. I tend to listen at "room-level" or the level at which i would normally watch tv, and the battery has not died on me as yet. the most i have worn this thing is 4 hours.

Charging is easy, just sit on the base, but its important to match the arrows (sit the thing on the bse correctly) or it won't charge. Chargind time is about a 4 -1 ratio. For every hour of use you are going to require four hours to get it back to a full charge.

Its really comfortable on the head and ears, easy to wear and listen to for a long time. Awesome for do chores as it stay put on the right shaped head.

Again for the price...awesome

Works as expected. This is a replacement headset for a 5 year old identical headset. Glad for the affordable pricing.

5.0 out of 5 stars I love these headphones! Jan. 27 2013
By Wendy
Verified Purchase
I have had these for quite a while now and they work great! I can now watch TV in bed at night next to my snoring husband and hear everything clearly! I love the auto off feature, so they turn off when I remove them from my head. The sound is nice and crisp and clear and I can use them anywhere in my house and still hear the TV in my bedroom. For the price, these are great for my needs.

2.0 out of 5 stars Not satisfied Feb. 28 2012
By JaY
Sound is very good, but it drop frequently, probably due to the switch that cut the sound when you take off the headphone to save energy. Veeeeery anoying to ear that continuous POP sound! I'm not satisfied at all with the product, i don't recommand it, but in the other hand, i'm very satisfied with the return policy from Amanzone. It's very easy to return, don't have to pay any returning charge, very good service! I will buy more in Amazone as long as they provide a good service like that!
