Design

1.has stereo speakers
Pioneer SE-NC21M
Sennheiser HD 4.40 BT
Devices with stereo speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better experience.
2.has an over-the-ear form
Pioneer SE-NC21M
Sennheiser HD 4.40 BT
Comfortable full-size form with earcups that fully enclose your ears. This model is loved for its increased sound isolation and the fact that it won't leak sound to your neighbors. It offers potential for maximum bass and loudness levels.
3.has a detachable cable
Pioneer SE-NC21M
Sennheiser HD 4.40 BT
With a detachable cable you can use alternative cables, and if the cable is pulled it will pop out instead of breaking.
4.sweat resistance
Pioneer SE-NC21M
Sennheiser HD 4.40 BT
Resistance to sweat makes it ideal for use while doing sports.
5.weight

120g

221.1g

We consider a lower weight better because lighter devices are more comfortable to carry. A lower weight is also an advantage for home appliances, as it makes transportation easier, and for many other types of products.
6.weather-sealed (splashproof)
Pioneer SE-NC21M
Sennheiser HD 4.40 BT
The device is protected with extra seals to prevent failures caused by dust, raindrops, and water splashes.

Sound quality

1.lowest frequency

10Hz

18Hz

The lowest frequency at which the device produces audio. The lower the low-frequency response, the stronger and juicier the bass.
2.highest frequency

22000Hz

22000Hz

The highest frequency at which device produces audio. The higher the high-frequency response, the clearer and crispier the treble.
3.has passive noise reduction
Pioneer SE-NC21M
Sennheiser HD 4.40 BT
The device sits tightly in place, creating an acoustic seal which reduces background noise and prevents your music from leaking out.
4.has active noise cancellation (noise control)
Pioneer SE-NC21M
Sennheiser HD 4.40 BT
This type of device allows you to listen at lower volume levels, causing less ear fatigue as you don't have to crank up the volume to overcome background noise. Ideal for plane rides and morning commutes.
5.sound pressure level

95dB/mW

113dB/mW

Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
6.impedance

44 Ohms

18 Ohms

Impedance is the device’s electrical resistance to the current being pushed through it. The lower the impedance, the easier it is to get higher volume and requires less power.
