Sennheiser prioritized sound isolation over long-term comfort. While the headband cushions and ear pads feel soft and comfortable. But don’t be discouraged if you’re considering using the HD 300 Pros as recording headphones; the comfort is adequate for monitoring.

The padding of the Ear-Pads is also durable. The seam at the top of the headband, on the other hand, does not inspire confidence. There have been claims of this splitting. Amidst this minor flaw, it is a high-quality product. Sennheiser has a reputation for producing high-quality products. Good build quality and high-quality components. Sennheiser is also extremely consistent.

As always Comfort can be dependent on a variety of aspects. How well you treat them and external conditions are always considerations. However, for the majority of cases, these will be more than adequate and should be durable

Similarly, the highs are perfectly clear and polished. Ear exhaustion is minimal during longer sessions, which is another plus point for this headset.

The high sound pressure level of up to 123 dB SPL @ 1 kHz also grants you sufficient extra room. These headphones can be quite loud. This a good option if you work in a loud environment or like to turn up the volume on a situation.

Because of the closed-back design, the sound stage is a little cramped. Bass frequencies build up quickly when combined with the tight seal. However, this is a feature shared by all closed-back headphones.

If you prefer a weightier bass response, these are for you. However, if you require extreme precision, there are better options available. Despite these minor quibbles, these headphones are light years ahead of the competition.

Monitoring Headphones

A good pair of monitoring headphones will have a neutral frequency response. This enables you to make precise evaluations. The highs should be sharp and clean. Mid-tones are correct. And bass tonality should not be overstated.

Long periods in the production company necessitate a high level of comfort. But for shorter sessions, you can get ahead with less-than-comfortable headphones. However, if you spend a lot of time in the studio, you’ll like a good fit and relaxed covering.
