EPOS I SENNHEISER ADAPT 135 USB II Specifications, Tests and Review

The EPOS I SENNHEISER ADAPT 135 USB II 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 on-ear. On-ear headphones are generally lighter. However, their design has fewer isolation capabilities, and therefore, for example, more sound can be let in and out compared to around-ear headphones. The weight of the headphones is 145.3 g.

The sound quality can be affected by many factors. When it comes to frequency range, a wider range will allow more detail to be heard during your listening session. However, it is important to note that the ability to perceive frequencies varies from person to person. The average person is able to hear frequencies in the range of 16 to 20 000 Hz. That is why headphone manufacturers usually focus on the 20 to 20 000 Hz range. If the lower values are lower, headphones are better able to reproduce bass tones, as these represent frequencies up to approximately 256 Hz. Conversely, values from 2 048 Hz upwards are treble. Thus, headphones with a high upper limit will provide a much more accurate reproduction of high tones. Headphones EPOS I SENNHEISER ADAPT 135 USB II have a frequency range of 20 - 20000 Hz. Overall, these headphones can reproduce sound up to 115 dB. However, be careful. Repeatedly playing music continuously at really high volumes can damage your hearing. To control the optimum playback volume you can use the manual control directly on the cable.

EPOS I SENNHEISER ADAPT 135 USB II has a boom–type microphone. A nice benefit of the microphone of the Headphones EPOS I SENNHEISER ADAPT 135 USB II is the Noise Canceling technology that suppresses ambient noise and allows a clearer sound recording to be captured.
