Design

1.has stereo speakers
Sennheiser PMX 685i
Sennheiser RS 170
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
Sennheiser PMX 685i
Sennheiser RS 170
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.sweat resistance
Sennheiser PMX 685i
Sennheiser RS 170
Resistance to sweat makes it ideal for use while doing sports.
4.weather-sealed (splashproof)
Sennheiser PMX 685i
Sennheiser RS 170
The device is protected with extra seals to prevent failures caused by dust, raindrops, and water splashes.
5.travel bag is included
Sennheiser PMX 685i
Sennheiser RS 170
The device comes with its own special case or pouch, which is useful for safe transportation.
6.has an in-ear form
Sennheiser PMX 685i
Sennheiser RS 170
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.

Sound quality

1.lowest frequency

18Hz

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

20000Hz

21000Hz

The highest frequency at which device produces audio. The higher the high-frequency response, the clearer and crispier the treble.
3.sound pressure level

120dB/mW

110dB/mW

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

16 Ohms

32 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.
5.has a neodymium magnet
Sennheiser PMX 685i
Sennheiser RS 170
Devices with neodymium magnets are lighter and more powerful than those which use ferrite magnets. They also have more bass and clear high notes.

Power

1.has a removable battery
