Poly - Plantronics Backbeat FIT 3200 Specifications, Tests and Review

​​The Poly - Plantronics Backbeat FIT 3200 are wireless headphones. The wireless connection allows absolute freedom of movement and with that increases the comfort of using the headphones. This feature is very popular, especially when using headphones every day. The limiting factor of wireless headphones is a certain delay in the sound transmission between the source and the headphones (almost indistinguishable for a normal user), as well as the need to charge them (in the case of wired headphones, the headphones are recharged by connecting the cable itself). The headphones use the Bluetooth 5.0 technology for sound transmission. The transmission range offered is up to 30 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. The weight of the headphones is 26 g.

The sound quality can be affected by many factors. When it comes to frequency range, the wider it is, the more detail you will hear when listening. However, the range a person can perceive is highly individual. The average person is able to perceive frequencies in the range of 16 to 20 000 Hz. So the most common frequency range you will see on the market is 20 to 20,000 Hz. Lower frequencies up to approximately 256 Hz are considered bass frequencies. Therefore, the lower the bottom value is, the better the headphones will reproduce bass. Conversely, values from approximately 2 048 Hz upwards are treble. That is why headphones with a high upper value will provide a much more accurate reproduction of high notes. Poly - Plantronics Backbeat FIT 3200 offers a frequency range of 20 - 20000 Hz. The sensitivity parameter determines how sensitively the headphones can receive the signal from the source. The higher the sensitivity value, the louder the headphones will be able to play with less power consumption. In general, a higher listening volume also means a higher power load for the connected device. So if you're buying headphones to listen to music from your mobile phone, for example, this is relevant to think about as you don't want to drain your phone's battery too much. Lower values around 85 dB are more suitable for listening in more quiet environments (for example, at home or in the office). Medium values of around 90 dB can provide good listening quality in noisier environments (for example, on public transport or in cafés). Headphones with high sensitivity values of around 100 dB or more are designed for really noisy environments, such as concerts. The Poly - Plantronics Backbeat FIT 3200 has 94 dB.

An important part of these headphones is the diaphragm, which, simply put, converts the electrical signal into a sound. The thin diaphragm that is around 6 mm thick can react quickly to changes in the audio signal and improves high-frequency listening. However, it is less sensitive to bass. The medium-thick diaphragm of around 10 mm provides a fairly balanced sound profile, allowing you to enjoy both bass and treble. A thicker diaphragm of around 20 mm cannot react so quickly to changes in the sound signal, thus impairing bass listening. However, it is more sensitive to higher frequencies. This model features the 13.5 mm. 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.

You will also definitely appreciate the special design of the construction that creates a seal that further blocks out ambient noise and which contributes to undisturbed music listening.

These headphones have a battery capacity of 90 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 Poly - Plantronics Backbeat FIT 3200 reaches up to 8 hour(s).

Charging time is 2 hour(s).
