We got some Logitech Noise Cancelling Headphones in work the other day. We’re just trying them out now. Very nice.
They use some kind of black magic power to block out all the washy background sound you normally get – ambient noise like motorway traffic, etc. As a result it does feel a bit like you’ve just landed on a plane and need to unblock your ears but the sound is amazing. Great bass too.A bit steep at ??60 though.
