HiFiMAN HE-400
Oppo PM-3
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
HiFiMAN HE-400
Oppo PM-3
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
HiFiMAN HE-400
Oppo PM-3
With a detachable cable you can use alternative cables, and if the cable is pulled it will pop out instead of breaking.
4.weight

440g

320g

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.
5.can be folded
HiFiMAN HE-400
Oppo PM-3
Foldable devices are easier to transport and take up less storage space.
6.travel bag is included
HiFiMAN HE-400

Sound quality

1.lowest frequency

20Hz

10Hz

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

35000Hz

50000Hz

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
HiFiMAN HE-400
Oppo PM-3
The device sits tightly in place, creating an acoustic seal which reduces background noise and prevents your music from leaking out.
4.sound pressure level

92.5dB/mW

102dB/mW

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

35 Ohms

26 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.
6.has a neodymium magnet
HiFiMAN HE-400
Oppo PM-3
Devices with neodymium magnets are lighter and more powerful than those which use ferrite magnets. They also have more bass and clear high notes.

Connectivity

1.has a 3.5mm male connector
HiFiMAN HE-400

A standard 3.5mm male connector is suitable for use with all MP3 players and computer sound cards.
