my new 46" Sharp LCD TV and got wonderfull surround sound.
I find them a lot lighter than the DP-IF5000 Sony Infrared Headphones (which I've enjoyed for many years), the only negative feature I found was the recharging station. I found that with a little practice, I can fit them in the right spot within a 10sec. span. I advise anyone who buys this product to keep a couple of AAA batteries handy if they are in a hurry. Another thing, you might have some distortion if used to watch a Plasma TV, but I didn't perceive any with the LCD TV. Overall, an excellent product for my purpose (watching late night tv w/surround sound without waking up my spouse).
Only complaint I could note is that docking the headphones to charge can be a little tedious because you have to perfectly line up the headphones in the cupped holders for the connecters to meet to charge, I catch myself alot of times swaying the headphones back and forth till the charge light pops up to state the charge is in progress.
Overall highly recommended and keeps my continued trust in Sony products
over the years I owned over 10 pairs of cordless headphones, mainly IF240 type, which seem to do great on power consumption, but not as good with sound quality and comfort.
With the IF240 I had to put new battery every 2-3 months or so.
The DS4000 require new battery every 2 weeks or so.
The reason I can not use the charger is because I am using more than one pair, so when put on the charger the second pair does not receive any signal.
She loves them, I'm without headphones... The digital input makes for incredibly clear sound. The design makes them comfortable for her too. I was worried she would have trouble placing on the stand properly to recharge them, but she learned faster than I did. She is legally blind, so that goes to show how easy it is when you start doing it. The other nice feature was the auto on/off when you put them on or take them off. Preserves battery strength.
When I decide to spend the money for a great headset, these are the one's I will get.
