Design And Build Quality


The Sennheiser HD 6XX headphones have an open-back design. This allows air to flow through the ear cups and helps to prevent heat buildup and sweating around the ears. 

The ear cups are large and well-padded with velour material. This means a comfortable fit for extended listening sessions. The headband is also padded and adjustable, ensuring a secure and comfortable fit for different head sizes.

The headphones are lightweight, weighing only 260 grams, which makes them easy to wear for long periods. The ear cups also swivel and rotate, which allows for a better fit and reduces pressure on the ears. Finally, the cable is detachable and replaceable. This is a great feature as it allows for easy replacement if it gets damaged.

Build Quality

The build quality of the Sennheiser HD 6XX headphones is good. The ear cups and headband are made of plastic, which makes them lightweight but durable. The velour padding on the ear cups is soft and comfortable. However, we’ve found that this type of material can wear out over time. The cable is thick and sturdy, which reduces the risk of tangling and damage. 

The headphones come with a 2-year warranty, which is reassuring for those concerned about durability.

Overall, the Sennheiser HD 6XX headphones have a simple but elegant design that is both comfortable and functional. The build quality is good, and the headphones feel sturdy and durable. The open-back design and velour padding provides a comfortable fit for extended listening sessions, making them a great choice for audiophiles and music enthusiasts alike.

Sound Quality

The Sennheiser HD 6XX headphones are known for their excellent sound quality. They are designed to provide a neutral and balanced sound signature. This makes them suitable for a wide range of music genres.


The bass response of the HD 6XX is accurate and well-controlled. It is not overly emphasized but still provides enough depth and impact to make music sound full and engaging. The sub-bass is slightly rolled off, which may disappoint bass heads, but it prevents the bass from overwhelming the other frequencies.


The midrange of the HD 6XX is where these headphones truly shine. Vocals and lead instruments are clear, present, and detailed, without any harshness or sibilance. The midrange is well-balanced, with no frequency range sticking out more than others.


The treble of the HD 6XX is smooth and extended, without any harsh peaks or sibilance. It is well-integrated with the rest of the frequency range, providing a cohesive and natural sound. However, some listeners may find the treble to be slightly recessed, which can make cymbals and high-pitched instruments sound less prominent.
