OneOdio A30 review: specs and price

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.

With a detachable cable you can use alternative cables, and if the cable is pulled it will pop out instead of breaking.

Foldable devices are easier to transport and take up less storage space.

The cable is designed to minimize tangling.

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

The device is designed in a way that allows sound to go out through the back of the ear cups, which usually have vents or perforations. This design provides very natural and accurate sound.

The device is dustproof and water-resistant. Water-resistant devices can resist the penetration of water, such as powerful water jets, but not being submerged into water.

Resistance to sweat makes it ideal for use while doing sports.

A long cable ensures more freedom of movement.

This type of device allows you to listen at lower volume levels, causing less ear fatigue as you don't have to crank up the volume to overcome background noise. Ideal for plane rides and morning commutes.

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

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

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

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.

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

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

The device sits tightly in place, creating an acoustic seal which reduces background noise and prevents your music from leaking out.

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.

The USB Type-C features reversible plug orientation and cable direction.

An indicator shows you when the device has low battery.

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

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 battery can be recharged and used over again.

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

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. Newer versions provide faster data transfers.

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 is a codec used for transmitting audio wirelessly with Bluetooth. It is developed by Qualcomm, and supports 16-bit audio at a bit rate of 384kbps.

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 Low Latency is a codec developed by Qualcomm. It uses Bluetooth 5.0 technology to provide low latency audio (around 40ms), which is useful when you want to avoid audio lag (e.g. when playing games).

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).

AAC is a codec that is used for Bluetooth audio. It supports 24-bit audio at 250kbps. Because it uses psychoacoustic modeling, it can provide better results than other codecs at a similar bit rate.

A standard 3.5mm male connector is suitable for use with all MP3 players and computer sound cards.

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

Ambient sound mode uses microphones to pass through ambient noises so that they can still be heard. It’s useful when you want to listen to music but also be aware of what’s happening around you, for example when you’re jogging but still want to be able to hear traffic.

Sensors can detect when they are removed from your ears so that the music is paused, saving battery life.

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

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

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.

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.

A headset is one headphone or pair with a built-in microphone. Headsets can be used for apps that require communication i.e. Skype, games with voice chat, mobile phones, etc.

There is a control panel on the cable, so you can easily operate the device without having to interact with it.

The global median price is determined by calculating the median value of all the prices available for a product, taking into account all markets.
