Sony Ericsson HPM-90 Specifications, Tests and Review

The Sony Ericsson HPM-90 are wired headphones. In the case of studio and professional DJ headphones, a wired connection is a standard and a necessity. In this case, connecting via cable reduces audio transmission delays and prevents unwanted battery drain as it would be in case of wireless headphones. The same is de facto true for gaming headsets. In case of headphones for normal music listening, the cable is rather a relic, although it still has its fans. However, the wireless option is much more popular for everyday use in today’s world.

The headphones are designed as in-ear headphones, which are inserted inside the ear to provide more or less isolation from ambient noise. The level of isolation may vary depending on whether the ambient noise isolation feature is present or not. One of the main advantages of these headphones compared to over-the-head ones is their stackability and easy portability. The weight of the headphones is 52 g.

The sound quality can be affected by many factors. To control the optimum playback volume you can use the manual control directly on the cable.

The Sony Ericsson HPM-90 has a microphone built directly on the cable.
