Summary: Mediocre performance
Review: Comparing these to my previous no-name wireless set (Radio Shack / Optimus) I find that they perform only a bit better and sometimes worse. Drop-outs are frequent as you move about the house. I have no other active 900MHz sources in the house either. On the good side, they are lightweight and the charging system (simply place them on the transmitter for re-charging) is very good. Although you wonder why the design is such that the charging prongs are on the left side of the base when the headphone unit has its on the right; meaning you can't simply take them off and place them directly on charge. Sound quality when locked-in and operating is better than my old wireless unit with less hiss.

Review: Finding the exact right frequency for the headphones is a never ending task. I bought the cheapest and upgraded until I got to the most expensive wireless headphones from Sennheiser. The bass doesn't come through and they just aren't acceptable. I returned them all one by one and got the Sony ones. Great bass and good reception. Sony only has 2 chanels though so if a lot of people have them, it becomes tougher not to interfere.

Summary: Disappointing
Review: I bought these for home and work, thinking I'd be able to listen to the MP3s on my computer while roaming from room to room.Well, forget that. Despite the claims that you can hear your music through "walls and ceilings", the reality is that even one or two thick walls will block clear reception. And I don't know where they came up with that "300 foot" range for the reception, but it's just not true. In addition, the power cord and audio jack are way too short, limiting your ability to position the transmitter to where it might do some more good. If you're looking to listen to your TV or stereo from across the room, this might be the product for you, but if you want to listen to music in the backyard, you'd be better off with something else.

Summary: Good design, decent sound quality, static, no isolation
Review: I bought these to be able to watch tv while my girlfriend is studying by my side. Connection is easy as 1-2-3. Immediately picked up the sound channel and produced nice sound. If you are into serious sound, then you should forget about wireless in the first place. You can wander around between the rooms and still have the reception. The thing i didn't like was this "900 MHz" technology. Just like in cordless phones there is interference and occasional noise. Funny thing - regular TV broadcast gave less noise then watching "Run Lola Run" on DVD. Go figure...
Yes, one more thing: sitting next to me on the couch my girlfriend said that she could hear sound coming pretty clear out of external earphone covers and kept asking me to turn it down. Even she was surprised when she found out that the volume level was pretty low. I'm thinking of returning them. Good design, decent sound quality, static and no sound shield.

Summary: Wireless can't be perfect
Review: I bought this product to be able to watch tv without disturbing my wife who doesn't like background noise when she's reading. For that purpose the Sennheiser RS-45 is great. I can sit wherever and move freely without being constrained by a cord. But don't expect too much. If you move around, there will be few disturbances in reception, just as there would be if you are moving around with a portable radio. Next room the reception is not too great, so you can forget about going to the basement with the headphones if the transmitter is somewhere else. In short: if you're looking for perfect sound quality, get regular headphones with a cord. If it's more important for you that you can move around a bit, the Sennheiser RS-45 is a good option.

Review: I bought this so I could enjoy my new Sony 36" HDTV at night without waking the baby. First, the instructions simply say "make necessary connections" and nothing more! My TV was set up by the delivery technicians, but I still am pretty knowledgeable about such things. There was no available "Audio Out" on my set, so I tried everything that was open on the back of my receiver. Nothing worked. Never did get sound. I am returning this product ASAP! Who needs the aggravation!??!? Maybe I'll try a Sony model.

Summary: Good value--excellent for wireless
Review: I had a pair of Sony wireless headphones that died due to a lighting strike not too long ago. For a replacement, I immediately looked at the Sennheisers because we use their wired counterparts at work (I work as an audio technician). I am very happy with the acoustics of the RS-45--the sound is natural, the bass response appreciable (better than most large-format headphones), and, after replacing my 900MHz cordless phone (I was planning on a 2.4GHz model, anyway), static-free. The batteries only last about 4:30, but I like the base's ability to charge a second one at the same time. Overall, these are excellent wireless headphones, and reasonably good headphones overall.

Summary: Auto-tuning is great!
Review: I had owned a pair of Sennheiser wireless headphones for about 2.5 years when they started dying - at low volume only. I bought the RS-45 headphones to replace them (at half the price of what I originally paid) and these are a significant improvement. I charged the batteries for 24 hours and then plugged them into my stereo. When I turned on the headphones they were perfectly tuned. I would have to regularly adjust the tuning a wee bit on the old pair, but not so with the RS-45. I use these almost exclusively for watching TV through the AV receiver and so far they've been flawless.
