The Harman / Kardon BTs are a pair of high-ish end over-ear Bluetooth headphones, and the current street price for them is around $200. They don't offer active noise-cancellation, but they are extremely striking and very obviously a premium product. So, are they worth two-hundred of your big ones?
Wireless, hardware, and battery life
I paired up the HK BTs with a Galaxy S4 and Note II with zero problems. Audio transmission sounded fantastic, and latency was well within the range I've come to expect with Bluetooth headsets.
