Excerpt: As some of the best Bluetooth headphones you can find, the Harman Harkar-BTs make use of advanced audio coding (AAC) and apt-X coding to punch out pristine audio. There are exchangeable leather cups that wrap completely around your ears and immerse you in your audio experience. Be aware that if anything brushes or bumps up against the outer earcups, the sound will resonate loudly through the headphones.
Pros: The leather ear pads are extremely comfortable, and they are detachable, just in case they don't fit your ears.
Cons: If anything bumps up against these headphones, the sound resonates through them and can be extremely loud.
