The RS110 II breathes new life into audio with its high sound quality and sleek design. Its detailed, balanced sound reproduction coupled with strong bass response makes it an ideal choice for all types of music and TV applications. Rediscover the world of wireless freedom with a touch of simplicity and elegance.
It is the WORST DESIGN ever from Sennheiser. The sound is good but it is designed to slide off your head if you look down. I hated it and bought the later series RS160-RS180.

Date first available at Amazon.com: October 2, 2001, OLD-SCHOOL!
A bit old but very good. I prefer the RS120's though. They're rechargeable. available from here pretty cheap…

The oldschool ones had their advantages over Sennheiser's current range, namely a rotary volume control, transmitter that switches on automatically when it gets a signal, no digital audio processing delay, longer range, and a more reliable link (no 'pairing' issues). For the RS120 and above, it was also easy to wall mount the dock with a 3M jumbo hook, whereas the new models need shelf space. It's a pity they don't still make the RS130/140 range - the RS110/120 were the comparatively sucky low end models.
These are awesome, I have 2 sets off the one transmitter and they are the best wireless headphones I've ever had
