Design

1.has stereo speakers
Koss PRO3AA
Koss PRO4AAT
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
Koss PRO3AA
Koss PRO4AAT
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.can be folded
Koss PRO3AA
Koss PRO4AAT
Foldable devices are easier to transport and take up less storage space.
4.travel bag is included
Koss PRO3AA
Koss PRO4AAT
The device comes with its own special case or pouch, which is useful for safe transportation.
5.cable length

2.4m

2.44m

A long cable ensures more freedom of movement.
6.Has a coil cable
Koss PRO3AA
Koss PRO4AAT
A coil cable offers more flexibility, as it can be further extended when in use, as well as retracted to take up less space when not in use.

Sound quality

1.highest frequency

20000Hz

25000Hz

The highest frequency at which device produces audio. The higher the high-frequency response, the clearer and crispier the treble.
2.lowest frequency

15Hz

10Hz

The lowest frequency at which the device produces audio. The lower the low-frequency response, the stronger and juicier the bass.
3.has passive noise reduction
Koss PRO3AA
Koss PRO4AAT
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

100dB/mW

95dB/mW

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

60 Ohms

250 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.

Connectivity

1.has a 3.5mm male connector
Koss PRO3AA
Koss PRO4AAT
A standard 3.5mm male connector is suitable for use with all MP3 players and computer sound cards.
