Grado SR80e Headphones

Prestigious Sound

Grado SR80e headphones can be driven by your smartphone

If you're in the market for a new pair of audiophile headphones without breaking the bank, the Grado SR80e headphones are tough to beat. These headphones are a an upgrade over one of the finest headphones ever produced with an all new driver design and new resonant distortion dampening polymer. Grado specially designed these truly excellent headphones with new drivers and durable plastic housings to move air and react to sound vibrations in a way that all but eliminate transient distortions, ensuring vibrant, lifelike sound quality.

Grado SR80e headphones feature classic Grado design

Designed and built at the Grado headquarters in Brooklyn, New York, the SR80e headphones feature an open-back design that produces a perfectly balanced soundstage. The new 4 conductor cable gives you a connection quality to match that of the actual headphones. The signal flows easily over the cable to reproduce sound with greatly improved, tight control of the highs a lows of your music. These headphones give you every bit of the midrange that you love, the bass you crave and the details you never knew your music had.

We've long been fans of Grado headphones and are really impressed by the quality of sound you get from this new $100 model. If you don't need the isolation of a closed-back design or a built-in microphone for cell phone calls, it's a great headphone for the money.

Input Connection
This is the manner in which the headphone amplifiers receive an input audio signal.
Output Connection
This is the manner in which the headphone amplifier will output the audio signal.
3.5mm Mini-Jack
Number of Outputs
