Excellent review. I am really surprised this is only the second review of M17 besides ichos. But these two reviews have enough information to be convinced

Superb product. I've been disappointed by FiiO products in the past (I don't like how they tune their iems and their entry level DAPs). But M17, M15 and og BTR3 are impressive stuff

What a beautifully written review. Keep em coming.

Good review. Been a long-time FiiO user currently using the M15 with no complaints. I am surprised by the size of the M17 and did not realize how thick it was until I saw it in your hand. Pics of the device in someone's hand I like, a better perspective of size.

yes pretty massive but manageable

Thats a temptation raising read for an M15 user, bilai

I have M15 but M17 outclassed it in everything, transparency, dynamics, realism, speed, resolution, power and slam. Selling M15..
