I have buyers dt770, fosteks t50 mk3. and some DIY on old AKG drivers. All these three pairs of headphones sound better over the wire than this audio source HIFIMAN 603. But in this budget, false ears over the air. This is the cheapest option with satisfactory sound quality and bluetooth 5.0. I note that there is not much difference in sound over a wire from a hi-fi main and wirelessly from a phone. I compared them with AKG 371 like, they choked when performing IGORRR and in general the sound quality, as for me, is on the shelf below.
