A Piece plastic with two bits of rubber on the for a grand sum of nearly £40 that's fine if it did the job some where near what it is supposed to do but for me it did not thank fully Amazon sept in and refunded the money back

I had a hard time getting the little black plugs on. One of the small plugs tore and I needed the small size. They need to have extra plugs available to bu separately.

Eine fantastische Erfindung. Nach einer kurzen Eingewöhnungszeit ist es wie ein Mikroskop für die Ohren. Man hört die Töne nicht mehr vor sich sondern steht gefühlt "im Ton drin".

Amazing, I didn’t expect these to be so good. I play non amplified flamenco Guitar. obviously the sound goes out forward and away from me. With these in it is a much fuller sound and louder. Similar effect to playing close to a wall, where the sound is reflected back to my ears. I don’t need to sit in front of a wall anymore. These have worked better than I could have every dreamed of. I have also added a thin lanyard so if one drops out of my ear I won’t lose it. I keep looking for where the battery fits lol. Cannot believe these are completely passive.

good deal
