This review is from: Sennheiser RS120 926 MHz Wireless RF Headphones with Charging Cradle (Electronics)
I bought these today (early September, 2004), and I'm pretty happy with them. The headphones themselves are light and fit well.. and the sound (to these non-audiophile ears) is good. There's excellent high frequency definition and good, solid bass without distortion.

There was no trouble in setting them up... plug them in and away they went (I had all the required adaptors and plugs in the box). I needed to tweak the headset-based tuning knob a bit, but since then it's been rock steady. I've had none of the drop-off or position-sensitive behaviour which I've read in other reviews. Still...it's early days and who knows what will happen when I start exploring the nether regions of the house and yard!

The thing I really want is a second set of headphones so that someone else can share the music or movie. I'm assured that they ARE avalable, but don't have a price yet.

So far, so good!


November update:

After a couple of months, I'm still happy with the sound. However, I HAVE discovered those annoying interfence sounds appear sometimes when I move around. Things get worse in my single story, metal roof house if it's raining.. in fact, at the moment I'm sitting at my desk about 15m from the transmitter, it's wet outside and there's an irritating level of intermittent interference. But I suspect that's just physics - maybe not even Sennheiser can do much about it!

Anyway.. we use them all the time, and they still sound good, so I'm retaining my 4-star rating.

July 2006 update:
It's nearly 2 years since I bought these headphones. I have them on at the moment - very loud - listening to to Roger Waters' "In the Flesh" DVD. They're still working well - the sound remains terrific. Friends who've been visited me have tried them and remarked on the quality of the sound. One of my better buys. I use them at least 2 - 3 times / week.

November 2009 Update:
Still going strong! I'm listening to the Eagles Farewell I concert DVD (recorded right here in Melbourne, Australia!) as I write this using these great headphones. I use them at least once a week and they still sound great. So what's that.. 5 years? In the meantime I bought some Philips equivalents to use while exercising on my treadmill (a VERY short-term thing!) and they, in comparison, are junk. So, hats off to Sennheiser.
