Features

First, I would like to tell you about some technical features which are important for a good sound. The impedance on this device is considerably higher than normal headphones since it is 300 Ohm. These headphones have a pretty wide frequency response from 10 to 41 kHz. It needs to be noted in the Sennheiser HD 650 review that their sensitivity is 103 dB.

Sound

The detail is truly amazing, the bass is quite full, and the sound seems relaxed and laid-back. The treble has a fabulous extension with a little elevated top end. The treble response also depends on the positioning of the headphones and ear shape.

Connectivity

This device is equipped with a 300 cm/9.9 ft long audio cable which is not detachable. Sennheiser HD 650 has a 3.5 mm jack connection and comes with a ¼ adapter (6.35 mm).

Comfort and design

Carrying this device is pretty comfortable since you get a nice bag with it. The headband of Sennheiser HD 650 is adjustable. The device is quite bulky and it does not fold. In addition, the headphones do not have a microphone. Despite their large size, they weigh only 260 g/9.1 oz.
