Devices with stereo speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better experience.
2.has an over-the-ear form
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.
3.has a detachable cable
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.
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.
The device is protected with extra seals to prevent failures caused by dust, raindrops, and water splashes.
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.
3.has passive noise reduction
The device sits tightly in place, creating an acoustic seal which reduces background noise and prevents your music from leaking out.
4.has active noise cancellation (noise control)
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.
5.sound pressure level
Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
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.
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.
2.has a rechargeable battery
The battery can be recharged and used over again.
3.has a battery level indicator
An indicator shows you when the device has low battery.
The time it takes to fully charge the battery.
5.has a removable battery
The battery is removable and can be replaced by the user if broken.
1.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. Newer versions provide faster data transfers.
3.has a 3.5mm male connector
A standard 3.5mm male connector is suitable for use with all MP3 players and computer sound cards.
4.maximum Bluetooth range
The device can connect at a greater distance via Bluetooth or infrared to another device.
5.supports Bluetooth pairing using NFC
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.
The device can connect to Wi-Fi.
1.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. Skype, games with voice chat, mobile phones, etc.
2.has a noise-canceling microphone
These microphones are designed to filter out background noise from the desired sound. Especially useful in noisy environments.
3.number of microphones
More microphones result in better sound quality and enable the device to filter out background noise.
4.control panel placed on a device
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.
5.Has an in-line control panel
There is a control panel on the cable, so you can easily operate the device without having to interact with it.
6.Has voice prompts
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.
It's the 'loudness' of the sound that the microphone can pick up.
2.lowest mic frequency
The lowest frequency that the mic can pick up. Better for recording bass.
3.highest mic frequency
The highest frequency that the mic can pick up. Better for recording treble.
