Thanks guys. This very helps. In A&K Michelle 3 drivers: 2x Knowles 22955 (probably for mid and bass) and JH 5-H for highs. For me more easily to get ed-29689 than sonion 2389, technically they seems equivalent, but how much difference I get in practice?

Hello. One of drivers in my Astell&Kern Michelle is damaged (very quiet sound) and I decided to replace it. This driver have marked JH 5-H which I can't find to buy and can't find specifications for it, but I finded another driver which looks very similar, Knowles ED-29689. So the question is...

yep i charge it all night but no luck :( also trying to reset but still nothing. rip my ha-2 SE :((

Hello. In DAC mod (mod B) one green led is lighting and red light is blinking. PC does not recognise device. In AMP mode (mod C) everything works fine. What I need to do to restore device functionality?
