I got akg y50 headphones, they got a detachable wire, so it is very practical to detach the cable and instead stick a 3.5mm bt 4.0 receiver (i ordered from china for few dollars) into these headphones with 3.5mm to 2.5mm adapter.
I am thinking about getting akg y50bt, the same model, but with internal bt. would that make a difference? Or does sticking a bt receiver into the aux in hole of wired headphones produce equal sound quality?
bt receiver info:
Bluetooth Version: 4.1
Frequency Range :2.4GHz
