Add a small portable DAC/amplifier and you get every benefit of wired plus superior sound quality. With one I started randomly telling apart new notes and passages from individual instruments in songs I heard tons of times before. This is with Ikko Zerda, picked up because it’s what was in stock, most likely this device isn’t special and anything is an improvement over built-in jack. (Lossless music and inexpensive SE215.)

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.)
