iPhone X – iOS 11.3 – bluetooth sounds hollow, play/pause not working from BT headphones
My X updated itself about two weeks ago to 11.3. I use Phaiser BHS-750 headphones and noticed that they sounded hollow while listening to Spotify on WiFi (no bass, almost monotone, very unusual)- I thought the headphones were defective and began messing with the equalizer to no avail. The headphones themselves have an equalizer option to adjust but didn’t work, nor did track ff/rw work, nor did play/pause and volume control was glitchy. I tested lightning->audio with some a pair of QC20i and it sounded measurably better (as expected).
Then in my car while driving, noticed the same effect (very familiar with how my car speakers sound so it wasn’t just my imagination or the headphones). Restarted the phone at a stop light, and right away the issues went away.
