Design and comfort

Sennheiser HD 400 Pro

In terms of design, the Sennheiser HD 400 Pro comes with a lightweight design and the Vellore earpad gives you the comfort you need during long sessions. In addition, open ear cups and angular transducers allow for a wide and transparent sound stage. Which makes the HD 400 PRO a reliable companion for those who put quality and accuracy above all else. The exterior surface has a matte and glossy finish and you can also see on the headset that it is quite sleek. Although it is plastic based, it does not look as cheap as other entry level headsets. In addition, it comes with a 1.8 meter long wire that can be used to connect a mobile device, PC and any controller.

Moreover, the design of the HD 400 Pro is similar to that of its predecessor. The lightweight design of the HD 400 PRO helps you stay focused for longer without damaging your ears. Articulating earcups, velor earpads and adjustable headbands allow for adaptability and comfort that perfectly match the shape of your head.

Our self-developed 120-ohm transducers are tuned for precision to deliver every detail of your mix. The highly efficient driver magnet provides clarity while its damping system manages ventilation. This distortion results in deeper bass that otherwise affects sound quality – a difference that professional users will appreciate.

The controls of this headset seem very simple besides being designed to hide it regardless at first glance. Moreover, on the left side cup you actually rotate the wheel which is attached to control the volume up or down. Pushing in the middle is how you toggle the mute, so it’s no easier than that. The bottom of the headset on the left is equipped with a flexible boom mic.

Connectivity, Pairing and AI assistant

Just like the Turtle Beach Recon 200 Gen2, it’s an over-the-top headset which is why it doesn’t have much Bluetooth or any connectivity options. The only connectivity option this headset has is the wire. Additionally, it come with a 3 m coiled cable with 3.5 mm jack plug and 3.5 mm jack plug to 6.3 mm adapter. Which is use to connect Xbox series X / S & Xbox one, PS4, PS5, Nintendo Switch and other mobile devices. It is wirelessly connect to any other devices like PC, Android smartphone and Xbox gaming.

Sennheiser HD 400 Pro is not a bad gaming headset in any way. It is comfortable, reasonably priced, works everywhere and has the right microphone. Whether that boosted bass mode is desirable depends more on your personal preference. But audio reproduction is rarely accurate-basically. It can give you almost enough bass or more, and nothing in between.

If that kind of product excites you, this headset might be worth a look. Given that the Sennheiser HD 400 Pro is a little over half the price of many of the best options on the market. You may have a hard time finding a good new deal.
