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

The EPOS I SENNHEISER ADAPT SC 135 USB 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 64 g.

The sound quality can be affected by many factors. When it comes to frequency range, the wider it is, the more detail you will hear when listening. However, the range a person can perceive is highly individual. The average person is able to perceive frequencies in the range of 16 to 20 000 Hz. So the most common frequency range you will see on the market is 20 to 20,000 Hz. Lower frequencies up to approximately 256 Hz are considered bass frequencies. Therefore, the lower the bottom value is, the better the headphones will reproduce bass. Conversely, values from approximately 2 048 Hz upwards are treble. That is why headphones with a high upper value will provide a much more accurate reproduction of high notes. EPOS I SENNHEISER ADAPT SC 135 USB offers 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.

For an even more undisturbed listening experience, the headphones have a special Active Noise Canceling feature.

EPOS I SENNHEISER ADAPT SC 135 USB has a boom–type microphone.
