Anyone encounter the K7 making a click sound then seemingly going into a standby mode with the two front LEDs blinking and no audio being outputted until you perform a power cycle?

Is this some sort of overheat protection perhaps?
Dear friend,

Which front LED is blinking?
USB +OPT Flashing at the same time: Overheating protection
COAX+LINE Flashing at the same time: DC protection
OPT+COAX Flashing at the same time: Overload protection

Best regards

No dedicated K9 thread yet but mine arrived today upgraded from the K7 :relaxed: This might interest some of you that wanted to turn off the lighting ring around the volume knob with K7 on K9 you can.

I'm also thinking of switching from K7 to K9. K7 suits everyone, I use it with a proprietary PL50 power supply, however, I often and for a long time go to my parents' house in another city for work, and I would like to have a second device for listening to music there too. I decided not to buy a second K7, but to try something new. Do you have experience listening to K7? Could you briefly describe the difference in sound between K7 and K9?

Only got the K9 today so only preliminary thoughts using FiiO FH9 IEM's. Slightly more open soundstage vs K7 the bass in particular seems to have more weight and impact to it vs K7. Not quite as smooth sounding as the K7 but slightly cleaner sounding if that makes sense? Noticeably more power than the K7, similar in tonality to my FiiO M11 Plus ESS which not surprising given they both employ ESS ES9068AS DAC's.

@FiiO, tell me, please, did you solve the problem with the volume drop in FiiO K7 BT? There will be no problems, as it was with the regular K7?
Dear friend,

That problem does not remains in K7 BT. Thanks for your attention.

Best regards
