Sound Characteristics and Strengths of Sennheiser HD650

The Sennheiser HD650 is an over the ear open-back headphones, and like all open-back types, the sound will leak out and might disturb the people around you. Still, there is an advantage of having open-back headphones, as usually, they have a bigger soundstage than other types. There is also a disadvantage too, which is a slight lack of bass when comparing it with closed-back headphones. We will need to take that into account when searching for a matching amp to pair with Sennheiser HD650. The frequency response of the HD650 is impressive, it is 10Hz – 41kHz. The nominal impedance of 300 Ohms already informed us that they are not easy to drive.

The padding at the headband and the fabric the Sennheiser HD650 uses makes it comfortable to wear but the headband may be too tight for others so is best to try them out first. The tightness could help with the stability while wearing and moving at the same time. For such a big headphone, the weight is considered quite light and probably will not be a hassle to wear them for a long duration. Especially with the breathability at the ear cups, it would make a great traveling music partner if it weren’t for the sound leakage disturbing other commuters.

For premium headphones, they are surprisingly musical sounding, and not that we are complaining, it is very enjoyable to listen to them. The warm and smooth sound quality really makes you relax, pulling you away from the surroundings and just focus on the music been played into your ears. Since Sennheiser HD650 is an open-back headphone, we expected the soundstage to be spacious and it doesn’t fail to meet the expectation. The instruments fill up the stage with accuracy and texture. The HD650 sounded a tad warmer than neutral sounding, making the overall sound reproduction full-bodied. Partly due to the solid bass output that is punchy and agile. It can go deep into the bass extension as well.

There is richness in the bass quality, not the boosted or exaggerated low-quality bass found on other headphones. The solid performance of Sennheiser HD650 does lack a bit of clarity and subtle details. Even played at high volumes, the subtle musical details are still not as audible that we would like. Sennheiser HD650 has that clean sound quality and ultra-low distortion which makes listening to our favorite tunes very alluring. It is never clinical sounding and doesn’t really trigger your analytical mind, you just want to enjoy your music. To nitpick a little, if there is a tad more brightness to the treble, it will be slightly livelier when it comes to vocal and string instruments.

It is truly a musical open-back headphone, for anyone who wants to listen to high fidelity sound quality, Sennheiser HD650 would not disappoint. The clean and high-resolution music delivery provides you with that premium HiFi feel, which triggered us to keep playing our favorite tunes non-stop.
