Legendary Polk sound in a Bluetooth Headphone
If you take your music with you everywhere-on a plane, on the subway or at home--the Hinge Wireless can be your essential travel companion. With over 40 years of experience crafting quality audio products, Polk has designed an active headphone for music and design lovers alike.

Because they're actively driven, the dynamic drivers provide an even richer, more detailed listening experience, while SoundClear Technology eliminates ambient noise from phone conversations and speakerphone echo as it delivers enhanced voice and speech recognition. The leatherette ear cushions sit comfortably on your ears, so you focus on the music. With the Hinge Wireless, nothing is compromised. Crafted with sound, comfort and convenience in mind. All for the love of music, movies and games.

Wireless convenience at your fingertips
Bluetooth wireless technology aptx and AAC delivers high-quality sound from your smartphone, tablet, computer or other compatible device and Near Field Communication (NFC) allows for ease and convenience of simply touching your Bluetooth device to pair and connect. Plus with a jog dial built into the right ear cup, you have intuitive one-finger audio and phone call control. The Hinge Wireless is powered by a rechargeable Lithium-ion battery that provides 12 hours of playtime.

Comfortable ergonomically designed headband and pivoting ear cups
The Hinge Wireless conforms to the shape of your head for a comfortable, secure - fit. The headband uses a lightweight, yet rugged aluminum hinge that enables the headphones to fold down into a compact, easy-travel size. Plush over-ear pads minimize outside noise and create a passive noise isolation technology that lets you focus only on the sound you want to hear.

Included single detachable cable with inline control
The cable enables you to use your headphones when Bluetooth isn't available or the headphone's battery has no charge. A gold-plated 3.5 mm connector is precision-machined to seat deeper into the source connection. Place your iPhone in landscape mode and the connector will not get in the way of your hand.
