Design
Devices with stereo speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better experience.
Comfortable full-size form with earcups that fully enclose your ears. This model is loved for its increased sound isolation and the fact that it won't leak sound to your neighbors. It offers potential for maximum bass and loudness levels.
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.
Resistance to sweat makes it ideal for use while doing sports.
The device is protected with extra seals to prevent failures caused by dust, raindrops, and water splashes.
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.
Sound quality
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.
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.
The device sits tightly in place, creating an acoustic seal which reduces background noise and prevents your music from leaking out.
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.
Devices with neodymium magnets are lighter and more powerful than those which use ferrite magnets. They also have more bass and clear high notes.

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.
Wireless devices allow users more freedom of movement.
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.
A standard 3.5mm male connector is suitable for use with all MP3 players and computer sound cards.

The device can connect at a greater distance via Bluetooth or infrared to another device.
Wi-Fi 6, released in 2019, is based on the IEEE 802.11ax wireless LAN standard. Designed to operate in all frequency bands between 1 and 6 GHz, it offers higher data rates and lower latency compared to previous Wi-Fi technologies.
802.11ac wireless works on the 5GHz frequency range. It offers higher transfer rates, improved reliability, and improved power consumption. It provides advantages for gaming and HD video streaming.
Wi-Fi 4 (802.11n) is a wireless standard released in 2009. It has faster transfer rates and improved security compared to its predecessors – a, b, and g.
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.
Features
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.
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.
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.
It supports a wireless charging standard such as Qi. To charge the device, you simply put it down on a compatible charging pad.
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.
An accelerometer is a sensor used to measure the linear acceleration of a device. A common application is detecting when a device changes between vertical and horizontal positions.
There is a control panel on the cable, so you can easily operate the device without having to interact with it.
