[COMBO] Acoustic Research AR-H1 & Opus #1S Digital Audio Player

Acoustic Research AR-H1  
Featuring an industrial design that is both appealing and comfortable, the AR-H1 gives music lovers an unbeatable listening experience, thanks to the 86mm planar driver with a neodymium magnet array that is considered among the best in its class. Frequency response is measured at 10-70kHz, with sensitivity rated at 100dB/V, and impedance at 33 ohms.

A true hi-resolution headphone should be as comfortable as it is sonically pleasing, which is why the AR-H1 features as a genuine leather headband and low resilience ear cushion that add up to hours of listening with no fatigue.
