Meanwhile, most popular audio codecs that work over BT cap bitrate, making lossless truly useless; most headsets and phones don’t support LDAC, and if you get a lucky combination that does music will likely stutter if you’re anywhere close to a busy area of the city or if your phone is in the wrong pocket.
(Where some wireless headsets do win is state of the art active noise cancellation, -30 dB when you’re in a really noisy place without an option to use IEMs or earplugs can be a bliss.)
Also audio amplification apps provide hearing aid features on even basic TWS earphones while a typical hearing aid can be very expensive.
