"Punchy, Detailed, Fast, and Deep Bass"
HiFiMan's HE-4 is the single-ended version of the company's critically acclaimed HE-5LE headphones. Both products have a very similar sound signature. Because the HE-4's magnets are only half the size as the magnets used in the HE-5LE, the HE-4 is noticeably lighter at 12.3 oz. compared to 14.2 oz for the HE-5LE.
The HE-4 uses a tweaked version of the orthodynamic headphone drivers used in HiFiMan's hugely popular HE-5 'phones. The open backed circumaural design delivers a huge and open sound. The planar magnetic drivers are like a scaled down version of electrostatic panel speakers that fit your head!
"The first thing I noticed immediately is how good the bass was from the HE-4. Punchy, detailed, fast and deep, very, very deep," raves marcusd in his HeadFi review for February 2011. "The soundstage of the HE-4 is what amazed me the most. I felt that I was listening to speakers rather than a headphone."
Comfortable for Extended Listening
The HE-4's earcups are lightweight, which means that you can enjoy these headphones in great comfort during long listening sessions. The cups rotate in two axes to conform to head shape.
Included with the HE-4 are a 10-ft headphone cable with a 6.5 mm plug and 5-ft portable headphone cable with a 3.5 mm 4-pin plug. |
