I'm wondering if anyone knows of a good pair of wireless (preferably bluetooth) open-back headphones. I'm looking for the following characteristics but am having trouble finding models that have all these features: Open back headphones Wireless preferably Bluetooth Over ear/comfortable Mic would be nice but not required Desired sound qualities: Good directional sound/expansive soundstage Sparkly treble without recessed mids Precise bass (don't like too much bass) I tried Sennheiser HD 558's with an external mic but did not like the very thick wire dangling down. Additionally, the treble sounded a bit muffled in my opinion. Ended up returning the HD 558's. Suggestions would be appreciated.
