This is the second time that this happened and so I’m now afraid to use my Fiio: During a listening session at low volume (L gain at 27 lvl my ears suddenly received an enormous and very ear destroying static distortion noise that left me with temporary ringing and my body was shaken. It was so bad that it only took 1 or 2 seconds because I literally ripped my IEM cable as fast and hard as I could from my ears. It felt as if that noise went straight into my ears in high gain mode at 100 volume, and trust me, I’m not exaggerating. I yet have to find out if my iem was damaged as well, but this is the only 4.4mm output I have and I’m so hesitant to listen to them again, all I did was play them again at lower volume without sealing into my ear canal and at least like that they still do sound.
The interesting / worrysome thing is that I actually had a similar experience with my first btr7. Only that the first time the distortion artifact static noises where not too horribly loud and they started more intermittently. Also the screen started to flicker and the logos to partially disappear. So I had time to quit the device.
In the 2 instances the btr7 was plugged for power and being used in Bluetooth mode.The last time it happened I noticed that when I unplugged the power line the noise stopped (that’s right, after ripping down my IEM cable my IEMs fell into the bed and i was left starino at them in disbelief because theyy look small and where making such a loud awful noise that they reminded me of two of those very loud noisy insects in the wild). Other settings were: hybrid filter mode, PEQ in use, harmonic protection in use, bal boost on, battery protection charge up to 60% was on, and the second time when the Fiio partially killed my ears I was listening thru an M chip iPad in AAC mode.
the question is: Is the manufacturer aware of this? Has the manufacturer or any of us traced down the problem and found if there is anything to preventing this. Like I said, I have suspicion that the problem is related to the battery state of charge, but I cannot afford to test further knowing that my ears could be gone over a stupid device, or just potentially breaking my earphones.
This is the reason for the first unit return. I doubt is a batch production issue as i bought the 2 units from different sellers.
As much as I been loving my btr7 , if there is no solution to this there is absolutely no way I can keep this unit knowing that my ears could be blown away at any moment. If you are outdoors it can also be extremely dangerous not only from the ear point of view but also affecting your equilibrium and making you lose your balance (yes trust me it gets that loud!).
