Overall Score 4.3 Represents average audio ecosystem compatibility score.
The Edifier W820BT have a weight of 260g, these weigh below 320g, which we consider as the highest average a headphone should weigh for comfort during long use. We take in account a lower weight best for the reason that lighter devices are more comfortable to carry.
Detachable cables are cables that have connectors on both ends. One end goes into your headphone cups, while the other end is inserted into a source device. Some new headphones, and not just the expensive ones, are coming with detachable cables, Edifier W820BT are one of those.
Edifier W820BT are foldable, which makes them more portable. Foldable headphones are easier to transport and take up less storage space.
Over-ear headphones have larger earpads that fit around your entire ear Edifier W820BT have a comfortable full-size form with earcups that fully enclose your ears. This design is loved for its increased sound isolation and the fact that it won't leak sound to your neighbors.
Edifier W820BT have stereo speakers, devices with stereo speakers deliver sound from independent channels on both left and right sides, this creates a richer sound and a better listening experience.
Passive Noise Cancellation uses well-designed ear cups to seal out environment noise. This is used for both in-ear earphones and over-ear headphones where the headphone itself will keep surrounding noise out. The Edifier W820BT sits tightly in place, creating an acoustic seal that reduces background noise and prevents your music from leaking out.
Low-frequency response measures if and how well an audio device reproduces low audible frequencies and if it makes any changes to the signal on the way through. Edifier W820BT's lowest frequency is at 20Hz, the lower the low-frequency response, the stronger and juicier the bass.
High frequency response measures if and how well an audio component reproduces high audible frequencies and if it changes to the signal while at it. Edifier W820BT's highest frequency is at 20,000Hz, the higher the high-frequency response, the clearer and crispier the treble.
Sound pressure is the average variation in atmospheric pressure caused by the sound, the sound level .i.e how loud something is can be perceived differently by different people so we need to have a way of getting an objective measurement of sound level expressed in numerical terms.
The sound pressure level, SPL, is the pressure level of a sound, measured in decibels, dB, Edifier W820BT's measurement is 100dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
The driver unit is the component that produces sound in the device, its size dictates the loudness of the headphone. Edifier W820BT driver unit is 40mm in diameter, bigger drivers are more powerful and can produce better bass.
Defined as the device's resistance to the electromagnetic current, when electricity flows through a conductor, it faces electrical resistance that counters the flow of current. The resistance of a wire is measured in ohms. Edifier W820BT's impedance is 32Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.
Neodymium magnets if used in audio devices produce a higher sensitivity and substantial sound output while using less power. They can help produce music at quite a high sound pressure level, SPL, with the use of high magnetic flux. The Edifier W820BT have this type of magnet.
If your headphones play wirelessly, cancel ambient noise, or enhance your listening experience with active features, their battery life will reduce over time. The device's battery life is given by the manufacturer, with longer battery life, you get to use it for longer and have to charge the device less often. Edifier W820BT's battery life is 80 hours
Edifier W820BT have a battery level indicator, an indicator shows you when the device has a low battery. The battery indicator lights indicate the charging status of your headphones.
A rechargeable battery is a type of electrical battery that can be charged, discharged into a load, and recharged many times, as opposed to a disposable or primary battery, which is supplied fully charged and discarded after use. Edifier W820BT's battery can be recharged and used over again.
Edifier W820BT can be used wirelessly, wireless devices allow users more freedom of movement.
Bluetooth is a wireless technology standard that allows data transfers between devices placed in close proximity, using short-wavelength, ultra-high frequency radio waves. Edifier W820BT has a v4.1
Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances. The Edifier W820BT can connect at a 10meters distance via Bluetooth or infrared to another device.
Being an industry standard audio plug, a standard 3.5mm male connector is suitable for use with all MP3 players and computer sound cards. This means that it is commonly used in stereo headphones to your phone or connecting your phone to an external amplifier, sound bars, your car radio, etc. Edifier W820BT has this connector giving it a wider range of connectivity with most of the sound devices out there. All plugs have at least a tip and sleeve with the number of rings that stand as a differentiating factor.
Edifier W820BT have only 1 microphones, more microphones result in better sound quality and enable the device to filter out background noise.
There is a control panel on the Edifier W820BT body, so you can easily access the volume control or remote without having to interact with a cable or another device it's connected to.
Edifier W820BT can be used as a headset. A headset is one headphone or pair with a built-in microphone. Headsets can be used for apps that require communication i.e. Zoom, Google Meet, Skype, games with voice chat, mobile phones, etc.
The period of time that warrant free repair and adjustment services in case of a malfunction occurring under normal use that has followed instruction manuals. When covered under the manufacturer’s warranty it is possible to get a replacement in the case of a malfunction. Edifier W820BT have a warranty period of 1 years
