The Hifiman HE400se delivers a natural sound with precise spatial representation thanks to its planar magnetic drivers and open design. With an efficiency of 91 dB, the HE400se works well with smartphones, tablets, portable high-resolution players, as well as high-quality stationary amplifiers.
Due to its open construction, the HE400se is more suitable for quiet environments, allowing for a natural, transparent, and very spacious sound image. Additionally, users are not completely isolated from the outside world and can perceive sounds like calls, phone rings, or doorbells. The specially designed headband ensures a secure fit and even weight distribution for long listening sessions without discomfort. Furthermore, the angled ear cushions provide high wearing comfort and ensure optimal sound transmission. Even after hours of listening, the HE400se remains comfortable and cool on the head, even in warm environments.
The HE400se headphones feature two 3.5 mm jacks on the ear cups, and the 1.5-meter headphone cable is equipped with a 3.5 mm plug, compatible with many smartphones, tablets, and portable music players. For home use with a sound system or in the studio, a 3.5 mm to 6.3 mm adapter is included.
