So I just got a pair of TC's (I know, I know), but I'm finding bass sounds like farts. Like, really bad. Treble and mids sound fine. I'm also hearing a metallic vibration in the frame that triggers when the right tone is hit in the right ear. Don't know how to describe it but it's like something is on the driver and vibrating. I've tried a variety of positions and ear cup configurations. I can hear potential but something is clearly not right.
Is my v281 completely unable to drive these or something? Or is there an issue with this set? Trying them out with this track
and it's a hot mess
Everything you say indicates they're broke. Those are some beaten up looking headphones. There is no fixing them on your end.
