DESIGN AND DIMENSIONS BlueTake i-PHONO BT420 EX
Product Type Headset - Bluetooth - wireless
Recommended Use TV, home audio, portable electronics, computer
Bluetooth Range (Operating Distance) 10 m Worse than 59 % of headphones rated.

The BlueTake i-PHONO BT420 EX are wireless headphones that allow unrestricted movement and thus increase comfort while listening to music. Because of this feature wireless headphones are especially popular with casual users. On the other hand, the limiting factor of wireless headphones is a certain delay in sound transmission between the source and the headphones (almost indistinguishable for the average user), and they also need to be charged regularly. Unlike wired headphones, where the headphones are charged by the connected cable itself, wireless ones must be charged separately. The transmission range offered is up to 10 m. The maximum range represents the maximum distance from the audio transmission source that the headphones can be used for wireless audio transmission. However, the maximum communication range can be affected by obstacles such as people, walls, etc. 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. For many users the frequency range is a key feature of headphones. The wider the range, the more detail and nuance you will hear while listening. However, every individual perceives frequencies differently, so the frequency range of headphones varies according to individual needs. The average person perceives frequencies in the range of 16 to 20,000 Hz, so headphones with a frequency range of 20 to 20,000 Hz are most commonly available. If you are looking for headphones with a good bass performance, you should aim for lower range values (bass represents frequencies up to about 256 Hz), while high range values (frequencies roughly above 2,048 Hz) will be better for reproducing high tones. The frequency range of headphones BlueTake i-PHONO BT420 EX is 20 - 20000 Hz.

The device connected to the headphones also plays a role most times. The lower impedance value (approximately 100 to 150 Ohms) is suitable for playback from mobile phones, laptops or other portable players that do not have a powerful enough amplifier. The lower impedance will ensure that the required volume level is achieved with less power, thus extending the life of the player. However, at the same time, with lower impedance, there is more distortion of the sound. Headphones with a higher impedance of around 250 Ohms and above are then more suitable for playback from really powerful signal sources or using a headphone amplifier, otherwise the sound coming out of them might not be loud enough. At the same time, higher-impedance headphones will also ensure less distortion in the sound. In the case of these headphones, the impedance reaches the 32 Ohm value. 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.
