The audio output through earphones is terrible. Always it feels as if the audio is clipping. This is major disappointment. NOKIA 7 plus audio output is bad compared to my old phone (moto m). I listen to only 24bit 96KHz FLAC audio. However I tried with MP3 format also.
Snapdragon 660 has Qualcomm Aqstic audio in it. According to the website https://www.qualcomm.com/solutions/mobile-computing/features/aqstic it should sound better than the cheaper phones.
But this is not the case with NOKIA. Has the team not enabled this ? I strongly feel so. I tried with all my headphones and earphones. The phone doesn't have enough power to drive them in full volume. Even with tiny earphones, the output is terrible. Audio is always clipping and getting compressed sometimes also. Dynamic range is also bad.
All this feedback given is without using the FX. Even with FX on, the ability to handle audio at high volume decreases only.
Something is wrong with the audio system.
Please do enable this in future update and fix the audio.
