AKG K840 Wireless Headphones

As New Condition since never used

Cost £400 back in the day from Sevenoaks HiFi in Kent. My Dad brought them but never used them.

These are not Bluetooth, they use a Hi Def RF Technology called 'Kleer Wireless Technology'

They produce CD quality sound without any lip-sync delay issues.

They pair automatically, you just plug the transmitter into the TV's headphone jack socket and turn it on, then turn on the headphones and they are instantly paired.

These headphones are very light-weight and produce a very high CD quality sound and you can wear them all day long. 

They also have no hissing sound when there are quiet scenes on the TV. I know a lot of wireless headphones suffer from this issue.

Charging is very easy, just use the supplied AKG USB cable and plug it into any mobile phone's USB charger.

These are No longer available and are almost impossible to find especially new ones likes these. The only other headphones I am aware off which use 'Kleer wireless Technology' are the Sennheiser RF175, but they are very bulky headphones by comparison, they also suffer from a persistent audible hissing sound in the  back-ground on quiet tv scenes - my friend had a pair of the Sennheiser RS175 and I was shocked at how bad the hissing was.

Please note, these were never used, but have some very light marks for storage, but still looks good as new.

Please check my other items for sale since I am also selling a pair of TDK WR700 Kleer headphones
