Sony MDR-PQ1 Specification Guide

MDR-PQ1

Marqii™ Headphones

Powerful sound

Big drivers push big sound. The 40MM drivers in Marqii™ phones deliver powerful 

bass and supreme sound right to your ears.

Locking headband

Find the perfect fit and lock it in. Inspired by ratchet bands on snowboard boots, the 

locking headband is easy to adjust and will stay in position for sure.

Cush feel

Whether it’s one track, one album or your entire library, the soft ear pads will leave 

your ears begging for more. Thick pads in the headband rest on your head for 

comfortable listening or around your neck for a little down time.

Detachable cord

Yeah, it’s pink. But it’s also smooth, flat and detachable.  Just one of the many details 

you’ll discover with Marqii headphones.
