Having used the headset nightly for past 3 weeks still impressed with the quality as my previous reviews. The only downside to-date is battery life! If you forget to switch off at the headset, the battery's die overnight. I went and bought a set of rechargeables and charger to save buying new ones as the normal batteries were replaced twice. In hinsight I would have bought the 120's with rechargeable base set.
 

Ordered wed's on net, delivered thurs am !st class post. Had no problems with tuning, sound quality very good. Range excellent even at the bottom of the garden no reduction in reception!.Great price, brilliant service, fast delivery. Buy them!
 

I ordered the RS110 Headphones on Wed's Morning over the web , for late night t.v use. I paid for normal 1st class post and expected delivery by saturday at the earliest. I was stunned when they arrived before 8.30 am next day! They were easy to set up, comfortable to wear and had none of the background "hiss" I expected after reading some reviews. The sound quality is excellant and the range and clarity unbelievable! I had the same reception at the bottom of the garden, as I did up in our second floor lounge at the front of the house. Look forward to trying them with the sound system, should summer ever return! Thanks Headphone World excellant service and product at a great price. Check out the prices on Sennheiser's Site!!
 

At first I had the same problem as L Paterson, but after a little experimentation with the channels and tuning options I got perfect reception throughout the house.
 

Initially I thought what a great product this would be but, sadly, the background "humming" noise in the ears is more annoying than poor sound quality. I've tried every way to stop the "interference" but it just doesn't work. Thinking of sending them back to supplier and looking to purchase either Bose or Sony (worth spending more money for the quality).
