Eh, that’s what I was afraid of. Thanks for the Radsone recommendation, I’ll look into that. Also considering the Sony’sHonestly? You’ll have a hell of a time getting close to the quality of higher end IEMs in a true wireless. A Radsone ES100 (Bluetooth receiver) and a short cable may be a good compromise.
The same pretty much applies to over-ears. I think the Audeze Mobius, Beyerdynamic Amiron wireless and HiFiMan Ananda BT are probably up there for the best audio quality in BT headphones. But dollar for dollar, you can get a lot more bang for your buck wired. I personally have a few BT headphone sets (Advanced Sound Model 3 with MMCX Bluetooth cable, which is a bit fussy but works well, and Sony’s Noise cancelling WH-1000MX3 which are excellent for air travel in particular).
