The first thing that struck me was the size of these puppies. A bit overwhelming…they were comfortable and the sound decent. But i had to return them because of their bulkiness.

It is the frst purchase of wireless headset I made. I recently bought a 42″ Bravia, with the blu-ray reader, and a home theater system. I am globally very happy of it. But, it is difficult to enjoy it once the kids are in bed… Ok, I had already put down 2500$, so why not put an extra 100$? I therefore went to Best buy and found this set. The only one truly available. Plus, it was from Sony, so I thought it was the best fist for my system.
Well, I hate it. Truly, this is the worst purchase I amde. I am right now looking for my ticket to turn it back. I hate is soo much, especially as I expected so much out of it.
I cannot complain too much about the quality of the sound. It is globally ok.
What is really bothering about the headset is the way it charges and the battery liftime (like mentionned in other reviews above).
It is sooo bad that I cannot tolerate Sony puts it on the market. It is an ok headset, sound-wise, but it is truly not useable:
- The battery will drain if not on the headset.
- To align correctly the headset requires special skills. If not properly aligned, it will drain.
- Even if aligned, a little something will make it misaligned, and therefore it will drain.
Now after just 3 weeks, the batteries are just permanently drained. The battery is dead, and will therefore not charge anymore. I spent 100$ on it, and only watched 6h, total of movie time. Also to be mentionned that at first charge, I only could watch 1:45min of movie before battery went bad. So do not choose to watch the ten commendments when you use it.
I hate it. Although, Sony provides on average quality items for the standard consumer, this item is just C-R-A-P!
I hope this review just avoids any more consummers from buying it.

I can’t believe the static and popping on these – what a horrific disappointment! I tried every conceivable configuration to escape the static and popping – but to no avail – only if I hold the transmitter about 6 inches from my head will it work. Surely I’m not the only one who bought these and noticed this issue. Trust – Broken. Goodbye Sony.

Broke as I was taking them out of the package, never even had a chance to try them. I spent alot of money for nothing.

Hello,The sound level from my new lap top is kinda weak.I picked up the 970 thinking that they would have ample volume.I plugged in the unit and found they wouldn’t charge (Battery was in backwards).After screwing around with the battery I found the 970 charged and the battery lasts and lasts.They would be good for music if they sounded good but alas the 970 must be for dialog.I also found the 970 needs to be “dialed in”.I can’t help but to think after all is dialed in with 970 that the wife could walk around the house work and still watch the soaps. UPDATE it’s been nearly a year…No denigration of quality what so ever.It’s why people buy Sony brand
