UMIDIGI AIRBUDS (6m)

Design

FIT

In-ear

The fit of the earbuds.

INGRESS PROTECTION (IP) RATING

IPX5

The first number of the IP rating refers to protection against dust, while the second number refers to protection against liquid. E.g. a first number of 6 denotes that it is completely dustproof, and a second number of 7 denotes that the device can withstand full immersion in water.

WEIGHT

8.6g

We consider a lower weight better because lighter devices are more comfortable to carry. A lower weight is also an advantage for home appliances, as it makes transportation easier, and for many other types of products.

DRIVER UNIT SIZE

13mm

The driver unit is the component that produces sound in the device. Bigger drivers are more powerful and can produce better bass.

LOWEST FREQUENCY

20Hz

The lowest frequency at which the device produces audio. The lower the low-frequency response, the stronger and juicier the bass.

HIGHEST FREQUENCY

20000Hz

The highest frequency at which device produces audio. The higher the high-frequency response, the clearer and crispier the treble.

✖Umidigi AirBuds U

Dolby Atmos is a surround sound technology that allows sounds to be interpreted as three-dimensional objects. By doing so, Dolby Atmos allows for immersive, 360-degree sound.

IMPEDANCE

Unknown. Help us by suggesting a value.

Impedance is the device’s electrical resistance to the current being pushed through it. The lower the impedance, the easier it is to get higher volume and requires less power.

SOUND PRESSURE LEVEL

Unknown. Help us by suggesting a value.

Devices with a higher sound pressure level are generally louder when supplied with any given audio source.

HAS A NEODYMIUM MAGNET

✖Umidigi AirBuds U

Devices with neodymium magnets are lighter and more powerful than those which use ferrite magnets. They also have more bass and clear high notes.

CHARGE TIME

2h

The time it takes to fully charge the battery.

BATTERY POWER

Unknown. Help us by suggesting a value.

Battery power, or battery capacity, represents the amount of electrical energy that a battery can store. More battery power can be an indication of longer battery life.
