EPOS I SENNHEISER IMPACT SDW 5011 Specifications, Tests and Review

The wireless headphones EPOS I SENNHEISER IMPACT SDW 5011 allow unrestricted movement, which increases the comfort of using the headphones. This feature is particularly popular with headphones for casual use. However, a certain limiting factor of wireless headphones compared to wired ones is a certain delay in sound transmission between the source and the headphones (but almost indistinguishable for the average user) and the need for regular charging. Unlike wired headphones, wireless headphones are charged separately. The maximum range of the headphones is up to 135 m. This range represents the distance from the sound source at which the headphones with wireless sound transmission can be used. However, the maximum range may be affected by obstacles such as walls or people, etc.

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 IMPACT SDW 5011 have a frequency range of 100 - 7500 Hz.

EPOS I SENNHEISER IMPACT SDW 5011 has a boom–type microphone. A nice benefit of the microphone of the Headphones EPOS I SENNHEISER IMPACT SDW 5011 is the Noise Canceling technology that suppresses ambient noise and allows a clearer sound recording to be captured.

In terms of headphone battery life as a significant factor in the purchase decision, it depends on what you want to use the headphones for and potentially how often you will be able to recharge them. Headphones with up to a few hours of battery life are more suitable for home use as they will require more frequent charging. Headphones with a battery life of around 10 hours or more are already more suitable for commuting and shorter journeys. However, nowadays you can also find headphones on the market that have a battery life in the higher tens to hundreds of hours. In this case, you do not have to worry about your headphones simply running out of power on longer journeys, and you will not have to deal with constant recharging. The battery life of the EPOS I SENNHEISER IMPACT SDW 5011 reaches up to 10 hour(s).

The standby battery life quoted by the manufacturer is 48 hours.

Charging time is 4 hour(s).
