Sennheiser RS120 926 MHz Wireless RF Headphones with Charging Cradle

Comment: I got these headphones on sale and I am very pleased with them. They have weird problems though. The fit is lousy. They fall off if you lean forward even a little. I use a stretchy headband to keep mine on. The volume dial and the tune dial are on the same side and it is really easy to use the wrong dial when adjusting the volume. The headphones lose the signal but it isn't very difficult to get it back. It's just annoying. I tried using regular alkaline batteries and they work great. I wear my headphones for seven or eight hours at a time. The alkalines lasted three days before I decided to switch back to rechargeables. I prefer to use rechargeable batteries, but I take them out of the headphones and charge them separately. The headphones don't fit on the charging stand all that well and the charging indicator light always stays on. Better to be safe than sorry! The range on these things is fabulous. The sound quality is excellent. The headphones come with lousy written instructions. You need an internet connection so you can go online and see how to set everything up. I love these headphones though and plan to buy another set in the near future.

Comment: IMO, headphones costing close to a hundred dollars ought to last for more than a year. The price made me think it was higher quality than it was. That attitude made me a sucker, because my headphones died after several months. The wiring inside it has such a small diameter, it wears out in no time. My headphones short-circuited one day, ceased to charge up, quit picking up any sound, and finally went dead. An examination of the wiring showed me it was little better than filament wire. Can't they afford to beef up the wiring so the device will last awhile?

Comment: I purchased this product after going through 3 iterations of the similar Sony wireless head phones. The Sony's always had terrible interference and therefore sound quality. The Sennheiser sounds great 99.9% of the time, with a just rare scratchy noise, which is to be expected with wireless. Fit is great, convenience of charging is great, and they look great in the living room. The only issue I've had is laying my head on a pillow may sometimes cause the tuning dial on the back of the ear piece to get moved, but it rarely happens and is not a big deal.

Comment: the only negative thing about these headphones is the fit.when looking down they slide off.

Comment: I tried it for a few days, but returned today.

First, the positive:
1) great sound quality when watching TV
2) range was pretty acceptable. Could go to the kitchen or bedroom and still get a very decent signal from the living room.
3) very comfortable in general. Your ears will get a bit too hot after extended periods, but hey, it's headphone! (of course leather would be better than cloth, but it'd be >$200 like the Bose). If you wear glasses it'll require a bit of adjustment so it doesn't put too much pressure on your glasses over the ears.
4) Battery seems to last enough. I used for several hours and still going strong. My Xbox batteries gave up much before the headset.


The reason I gave it 3-stars and the reasons for my return are:

1) It DOES HAVE a constant hiss in the background. Differently than most other reviews I found it quite noticeable, especially on interviews and dialogs, or when your music has frequent level changes like classic music, jazz, etc. I'm using to play RPG games on my Xbox, so your mileage may vary. As RPG games have lots of dialogs and parts with subtle music mixed with high intensity action, any small interference gets *very* annoying after a few hours.

2) Also noticed there's an audible high pitch noise when the xbox is loading something from the DVD. Again, it's only noticeable during silent parts, but when you're playing Mass Effect 2 that's pretty much the entire time. I tried moving away the xbox and using shielded cables but no improvement. Also tried adjusting the frequency on the headphone and changing the station without luck.


In summary, when watching regular TV or other source with constant high sound the automatic gain control will work fine and you can barely notice the hiss. If you're planning to play videogames (specially RPGs) or other sources with long pauses and subtle music, maybe you should look for something else.
