Sony WH CH720N have a weight of 192g, these weigh below 320g, which we consider as the highest average a headphone should weigh for comfort during long use. We consider a lower weight best because lighter devices are more comfortable to transport. Detachable cables are cables that have connectors on both ends.
One end goes into your headphone earpieces, while the other end is inserted into a source device. Some new headphones, and not just the expensive ones, are coming with detachable cables, Sony WH CH720N are one of those. Twisted headphone cables can be a great source of annoyance and inconvenience, Sony WH CH720N's cable is designed to minimize tangling.
Constant twisting of the cables can also lead to bends in the copper wires, affecting sound quality, or
completely damaging your headphones. A long cable ensures more freedom of movement, but remember that every cable based on the conducting material used has a certain amount of parasitic resistance, inductance, and capacitance. How much depends on the length and construction.
Sony WH CH720N comes with a 1.2meters cable. Over-ear headphones have larger earpads that fit around your entire ear Sony WH CH720N have a comfortable full-size form with earcups that fully enclose your ears. This design is loved for its increased sound isolation and the fact that it won't leak sound to your neighbors.
Sony WH CH720N have stereo speakers, what this means is that Sony WH CH720N's speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better listening experience. Active noise cancellation uses more advanced technology to reduce unwanted ambient sounds. How it works, it detects and analyzes the sound pattern of incoming noise and then inverts the soundwaves to cancel it out.
In simple terms, it's like taking +1 outside (noise from your surrounding) and adding -1 inside (counter sound within the device) to make 0 resulting in a reduced level of noise.
Sony WH CH720N allow 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. Passive Noise Cancellation uses well-designed ear cups to seal out unwanted noise.
This is used for both in-ear earphones and over-ear headphones where the headphone itself will keep surrounding noise out. The Sony WH CH720N sits tightly in place, creating an acoustic seal that reduces background noise and prevents your music from leaking out. Low-frequency response measures if and how well a particular audio device reproduces low audible frequencies and if it makes any changes to the signal on the way through.
Sony WH CH720N's lowest frequency is at 20Hz, the lower the low-frequency response, the stronger and juicier the bass. High frequency response measures if and how well a particular audio device reproduces high audible frequencies and if it makes any changes to the signal while at it. Sony WH CH720N's highest frequency is at 20,000Hz, the higher the high-frequency response, the clearer and crispier the treble.
Sound pressure is the average variation in atmospheric pressure caused by the sound, the sound level .i.e how loud something is can be perceived differently by different people so we need to have the means to get an objective measurement of sound level expressed in numerical terms.
The sound pressure level, SPL, is the pressure level of a sound, measured in decibels, dB, Sony WH CH720N's measurement is 99dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
The driver unit is basically a mini speaker that produces sound in the device, its size dictates the loudness of the headphone. Sony WH CH720N driver unit is 30mm in diameter, bigger drivers are more powerful and can produce better bass. Impedance is the device's resistance to the electromagnetic current, when electricity flows through a wire, it faces electrical resistance that counters the flow of current.
The resistance of a wire is measured in ohms. Sony WH CH720N's impedance is 31Ohms, the lower the impedance, the easier it is to get higher volume and requires less power. If your headphones play wirelessly, cancel ambient noise, or enhance your listening experience with active features, their battery life will reduce over time.
The device's battery life is given by the manufacturer, with longer battery life, you get to use it for longer and have to charge the device less often. Sony WH CH720N's battery life is 50 hours
It takes 3.5 hours to fully charge the Sony WH CH720N's battery. It is recommended to fully charge the battery before using the headphones for the first time or when they have been unused for extended periods.
A rechargeable battery is a type of electrical battery that can be charged, discharged into a load, and recharged many times, as opposed to a disposable or primary battery, which is supplied fully charged and discarded after use. Sony WH CH720N's battery can be recharged and used over again. Sony WH CH720N can be used wirelessly, wireless devices allow you more freedom of movement not limited by a cable.
Bluetooth is a wireless technology standard that allows data transfers between devices placed in close proximity, using short-wavelength, ultra-high frequency radio waves. Sony WH CH720N has a v5.2
Sony WH CH720N support USB TYPE-C, an industry-standard connector for transmitting both data and power on a single cable. The USB-C plug is now part and parcel of most current laptops, phones, and tablets, it features reversible plug orientation and cable direction.
Sony WH CH720N support LDAC, a codec developed by Sony
which allows streaming high-resolution audio over Bluetooth connections at up to 990 kbps at 32 bit/96 kHz. It is capable of a very high bitrate of 990kbps, which provides high-resolution audio. Sony WH CH720N support AAC, 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. Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances.
The Sony WH CH720N can connect at a 10meters distance via Bluetooth or infrared to another device. Being an industry standard audio plug, a standard 3.5mm male connector is suitable for use with all MP3 players and computer sound cards. This means that it is commonly used in stereo headphones to your phone or connecting your phone to an external amplifier, sound bars, your car radio, etc.
Sony WH CH720N has this connector giving it a wider range of connectivity with most of the sound devices out there. All plugs have at least a tip and sleeve with the number of rings that stand as a differentiating factor. Sony WH CH720N support 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. Sony WH CH720N have only 2 microphones, more microphones result in better sound quality and enable the device to filter out background noise. Sony WH CH720N use a noise-canceling type of microphone, these microphones are designed to filter out background noise from the desired sound.
Especially useful in noisy environments. The magnitude of the analog or digital output signal from the microphone with that input stimulus is a measure of its sensitivity. Microphone sensitivity is a measurement of a microphone's efficiency as a transducer (how well it converts acoustical energy to electrical energy). Sony WH CH720N microphone sensitivity is measured at -42dBV/Pa
The highest mic frequency of a microphone is defined as its upper limiting frequency.
With today's microphones, you can reach a frequency high reaching up to 140 kHz. Sony WH CH720N's highest mic frequency is 8,000Hz, the highest frequency that the mic can pick up. Better for recording treble.
The lowest mic frequency of a microphone is defined as its lower limiting frequency. With today's microphones, you can have a frequency starting from around 1Hz. Sony WH CH720N's lowest mic frequency is 50Hz, the lowest frequency that the mic can pick up.
Better for recording bass. Sony WH CH720N support ambient sound mode, which 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 having a jog but would still want to be able to hear traffic.
Sony WH CH720N have a mute function, they have an option to mute/unmute a conversation directly from the device. The mute function means that you unilaterally turn off the microphone, but you can still hear the other party's voice. Sony WH CH720N support multipoint, which 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 Sony WH CH720N 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. Sony WH CH720N 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. Zoom, Google Meet, Skype, games with voice chat, mobile phones, etc.
Carrying headphones without a case, or putting them in bags without a casing can easily put them at risk of getting damaged. The Sony WH CH720N come with their own special case or pouch, which is useful for safe transportation.
