AKG K275
Ultrasone PRO 750
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
AKG K275
Ultrasone PRO 750
With a detachable cable you can use alternative cables, and if the cable is pulled it will pop out instead of breaking.
4.weight

295g

295g

The device comes with its own special case or pouch, which is useful for safe transportation.

Sound quality

1.lowest frequency

16Hz

8Hz

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

28000Hz

35000Hz

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
AKG K275
Ultrasone PRO 750
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

109dB/mW

94dB/mW

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

32 Ohms

40 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.driver unit size

50mm

40mm

The driver unit is the component that produces sound in the device. Bigger drivers are more powerful and can produce better bass.

Connectivity

1.Can be used wirelessly
AKG K275
Ultrasone PRO 750
Wireless devices allow users more freedom of movement.
2.has a 3.5mm male connector
AKG K275
