Libratone Zipp Mini 2 review: specs and price

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.

Volume is the quantity of three-dimensional space enclosed by the product's chassis or, in simpler terms, the space the product occupies.

A speaker driver is an individual transducer that converts electrical energy to sound waves. More drivers may result in better sound quality.

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

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

There is a control panel on the device 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.

The device comes with its own special case or pouch, which is useful for safe transportation.

You can operate the device easily, by pressing the screen with your fingers.

The device is protected with extra seals to prevent failures caused by dust, raindrops, and water splashes.

Devices with stereo speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better experience.

Devices with a subwoofer have a higher quality, deeper bass.

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

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

Audio output power is based on the number of speakers and their power in watts. High audio output power results in loud, clear sounds.

A passive radiator is a type of driver (speaker) that doesn't have a voice coil and a magnet. The sound vibrations produced by a passive radiator depend on its mass and the size of its enclosure. It is usually used in combination with a woofer to produce deep bass tones.

More microphones result in better sound quality and enable the device to filter out background noise.

These microphones are designed to filter out background noise from the desired sound. Especially useful in noisy environments.

Signal-to-noise ratio is a measure that compares the level of a desired signal (meaningful information) to the level of background noise (unwanted signal), the bigger the less perceived noise.

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.

The device's battery life (when in use) as given by the manufacturer. With a longer battery life you have to charge the device less often.

The time it takes to fully charge the battery.

An indicator shows you when the device has low battery.

The battery can be recharged and used over again.

The battery is removable and can be replaced by the user if broken.

It supports a wireless charging standard such as Qi. To charge the device, you simply put it down on a compatible charging pad.

How much power the device consumes when it's switched on.

The more power per year a device consumes, the less energy efficient it is, making it more costly over time.

Multipoint allows you to link to more Bluetooth devices and switch between them. For example you can easily switch calls from one device to another without having to manually disconnect and reconnect.

Bluetooth is a wireless technology standard that allows data transfers between devices placed in close proximity, using short-wavelength, ultra-high frequency radio waves. Newer versions provide faster data transfers.

Device supports fast Bluetooth pairing using NFC so it can communicate with other devices over Bluetooth. You can fastly pair devices without entering a code by simply holding one device next to the device with which it is to be paired.

With a standard mini jack socket, you can use the device with most headphones.

An auxiliary input allows you to play other audio sources by connecting them through a simple audio connection like a 3.5mm jack, i.e for MP3 or portable DVD/CD player.

aptX Lossless is an audio codec for Bluetooth devices that is developed by Qualcomm. It supports high quality 16-bit/44.1kHz audio (at a maximum bit rate of 1200kbps). This codec provides CD-quality audio without any loss of data.

LDAC is a codec developed by Sony for Bluetooth audio. It is capable of a very high bitrate of 990kbps, which provides high resolution audio. It can also automatically adjust to a lower bitrate of 330kbps or 660kbps to increase stability.

aptx Adaptive is an audio codec for Bluetooth devices that is developed by Qualcomm. It has a variable bit rate (between 279kbps and 420kbps), which means it can adjust the bit rate for different scenarios, such as listening to HD audio or reducing interference from other devices.

aptX HD is an audio codec for Bluetooth devices that is developed by Qualcomm. It supports high quality 24-bit audio (at a bit rate of 576kbps).

Wireless devices allow users more freedom of movement.

This technology allows the users to use their smartphone as a remote control for the device.

You can use your voice to control key functions of the device and you can easily access your device without pushing any button.

A built-in FM radio tuner allows you to listen to most of the live-broadcasted FM radio stations without using the internet.

With voice prompts, you will automatically receive information via audio messages – for instance, you may find out that the battery is running low, and it's time to recharge the device.

The device has an option to mute/unmute a conversation directly from the device.

The power bank feature allows you to use the battery to charge other devices, such as your smartphone.

A sleep timer is a function that shuts off the power after a preset amount of time.

The internal storage refers to the built-in storage space available in a device for system data, apps, and user-generated data. With a large amount of internal storage, you can save more files and apps on your device.
