Design

1.has stereo speakers
Koss KDE250
Sennheiser CX 150BT
Devices with stereo speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better experience.
2.sweat resistance
Koss KDE250
Sennheiser CX 150BT
Resistance to sweat makes it ideal for use while doing sports.
3.weather-sealed (splashproof)
Koss KDE250
Sennheiser CX 150BT
The device is protected with extra seals to prevent failures caused by dust, raindrops, and water splashes.
4.travel bag is included
Koss KDE250
Sennheiser CX 150BT
The device comes with its own special case or pouch, which is useful for safe transportation.
5.has an in-ear form
Koss KDE250
Sennheiser CX 150BT
The in-ear device is ultracompact and lightweight, with little or no interference with earrings, spectacles, hats, or hairstyles. It is inserted in the ear canal itself and blocks out a lot of environmental noise. It has stronger bass tones and is unlikely to fall out of the ear.
6.has an earbud form
Koss KDE250
Sennheiser CX 150BT
The earbud form is ultracompact and lightweight, with little or no interference with earrings, spectacles, hats, or hairstyles. For some people it is more comfortable than in-ear form.

Sound quality

1.lowest frequency

40Hz

17Hz

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

20000Hz

20000Hz

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
Koss KDE250
Sennheiser CX 150BT
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)
Koss KDE250
Sennheiser CX 150BT
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

112dB/mW

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

16 Ohms

28 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.
