I can’t praise this item enough, for £20 including delivery it is superb value. The sound quality from the microphone is equal, if not better than my Olympus LS10. The sound from the headset has open a new doorway as I suffer from tinitus in both ears & I can hear more content with the headset on than with just my ears.
There is a video demo here made using Camtasia Video Capture software.

A great piece of kit for music makers.

You can’t complain at £20 can you - that’s not bad at all.
