The wireless headphones Sennheiser HD 450BT allow unrestricted movement, which increases the comfort of using the headphones. This feature is particularly popular with headphones for casual use. However, a certain limiting factor of wireless headphones compared to wired ones is a certain delay in sound transmission between the source and the headphones (but almost indistinguishable for the average user) and the need for regular charging. Unlike wired headphones, wireless headphones are charged separately. The headphones use the Bluetooth 5.0 technology for sound transmission.
This type of headphones has a design that surrounds the entire ear to improve isolation from external noise. As a result, they provide a great quality of listening without interference. However, unlike on-ear headphones, they are usually heavier and less suitable for frequent wearing. The weight of the headphones is 238 g. Although these are over-the-head headphones that are normally characterized by their bulky nature, this model can be folded into a more compact form. This makes them easier to fit into a backpack or bag

The sound quality can be affected by many factors. When it comes to frequency range, a wider range will allow more detail to be heard during your listening session. However, it is important to note that the ability to perceive frequencies varies from person to person. The average person is able to hear frequencies in the range of 16 to 20 000 Hz. That is why headphone manufacturers usually focus on the 20 to 20 000 Hz range. If the lower values are lower, headphones are better able to reproduce bass tones, as these represent frequencies up to approximately 256 Hz. Conversely, values from 2 048 Hz upwards are treble. Thus, headphones with a high upper limit will provide a much more accurate reproduction of high tones. Headphones Sennheiser HD 450BT have a frequency range of 18 - 22000 Hz. Overall, these headphones can reproduce sound up to 108 dB. However, be careful. Repeatedly playing music continuously at really high volumes can damage your hearing. Total Harmonic Distortion of these headphones is Audio Output | Total Harmonic Distortion. The value quoted by the manufacturer is usually the average distortion over all reproducible frequency bands. This is not a crucial parameter to decide on when making a decision, but on the other hand, keep in mind that higher harmonic distortion can negatively affect sound quality.
The design of the headphones and their ear cups can also affect the quality of the audio output. The closed design does not allow ambient noise or sound from the headphones to flow outwards. Not only will you enjoy music in noisy environments, but you won't disturb anyone while enjoying listening session. The closed-back design makes the headphones suitable for the office or for travel.
For an even more undisturbed listening experience, the headphones have a special Active Noise Canceling feature.

These headphones have a battery capacity of 600 mAh. In terms of headphone battery life as a significant factor in the purchase decision, it depends on what you want to use the headphones for and potentially how often you will be able to recharge them. Headphones with up to a few hours of battery life are more suitable for home use as they will require more frequent charging. Headphones with a battery life of around 10 hours or more are already more suitable for commuting and shorter journeys. However, nowadays you can also find headphones on the market that have a battery life in the higher tens to hundreds of hours. In this case, you do not have to worry about your headphones simply running out of power on longer journeys, and you will not have to deal with constant recharging. The battery life of the Sennheiser HD 450BT reaches up to 30 hours.
Charging time is 2 hours.
