Sennheiser HD 4.50 BTNC HEADPHONES REVIEW

The Sennheiser HD 4.50 BTNC are pretty versatile over-ear headphones for most applications. They have a customizable and above-average sound. They are well built, comfortable and sturdy enough to walk, even if they are not the ideal headset for athletes. They provide ample commuting space but do not have as many features or options that you can control through the app, such as the PXC 550 Wireless.

Design

The Sennheiser HD 4.50 is similar to the PXC 550 Wireless with slightly less high quality build quality. They are still robust headphones that do not break easily and sit comfortably thanks to the well padded ear cups. Unfortunately, they tend to feel a little tighter on most heads, and the included carry case feels a bit cheap for its price range. On the other hand, because they are a bit tight and wireless, they are sturdy enough to work and fold so that they do not take up much space in your pocket.

Sound

The Sennheiser HD 4.50 BTNC is an above-average-sounding pair of closed over-ear headphones. These headphones have excellent, deep, pounding and consistent bass, a balanced but forward-sounding midrange and a difference in height that lacks detail and brightness. Overall, they would be a very good choice for most genres, especially bass-heavy ones, but might not be the best for classical or vocal centric music, as they are mid-range forward and have no treble.

Isolation

The Sennheiser HD 4.50 BTNC Wireless provides a decent seal on most ears. This prevents them from leaking even at higher volumes and prevents a good sound from seeping into the earcups. This and the above-average noise reduction make them a great option for commuting, even if you hear something from the outside world in really noisy environments.

Microphone

The Sennheiser HD 4.50 BTNC have an average integrated microphone. In quiet environments, the recorded or transmitted voice with this microphone sounds relatively thin and noticeably muted. In noisy situations, they are better than most Bluetooth microphones and can separate speech and background noise in moderately loud environments, such as a busy street.

Active Features

The Sennheiser HD 4.50 BTNC have good battery life and proper app support. They do not last as long or have as many customization options and features as the PXC 550 wireless, but they have a good EQ and 22 hours of uninterrupted playback that will easily withstand you all day, even under heavy use. Unfortunately, they do not have automatic shutdown time to extend battery life, and you do not have as much control over the noise reduction or sound profile as some of the newer versions, such as the Sony WH-1000XM2.

Connectivity

Like the PXC 550 Wireless, the Sennheiser HD 4.50 can be paired with multiple devices at the same time, supports NFC and has an above-average wireless range. They also come with a standard audio cable that works with most devices, but no in-line microphone compatible with consoles and PCs. Unfortunately, like most bluetooth headphones, they have a bit too much latency, which is not ideal for gaming or watching video content.

Conclusion

Mixed Usage

The Sennheiser HD 4.50 BTNC is a very versatile headphone in most cases. They have a very customizable sound like the PXC 550, but they lack some of the better features. They are exceptionally comfortable, stable and durable and isolate relatively well in noisy environments. This and their low leak rate make them a good decent option for most applications, especially when traveling and in the office.

Critical Listening

Above average for critical listening. The standard audio for these headphones is better than average and should sound good enough for most listeners. They may sound a bit harsh as the highs and highs of the mid and low highs kick off slightly and the instruments and vocals move to the top of each track. However, thanks to the CapTune app, you can customize the sound profile to suit your tastes and preferences, making it versatile enough to suit most listeners. Unfortunately they have a relatively small sound due to their closed design.

Commute/Travel

Above average for commuting. They block a good amount of noise, they are quite comfortable, but their control scheme is not as appealing as some of the other wireless headphones we’ve tested.

Sports/Fitness

Above average for sports. The Sennheiser HD 4.50 BTNCs are not specifically designed for high-intensity activities, but are strong enough to jog with. They have a comfortable fit and provide good control over your audio. Although they will work for some time under stressful conditions, they can warm up a bit.
