TWC-M17 Trpt Practice Studio : Incredible noise reduction

Noise reduction is really good and it's indeed possible to play without the neighbours to hear you (vocal conversation noise intensity I would say).

Really good mute to practice alone but the pitch correction (a quarter of a whole step) is hard to make on the whole range. So it's hardly possible to play with other musician due to this pitch drift.

Also it's not easy to blow and it's less responsive. Which improve endurance and make it a relieve to play without the mute afterwards.

I would definitively buy it again as it allows me to practice everyday, everywhere.

Just note the existence of the TWC-M22C compact that can fit in the bell which is more convenient for transport.
