Detachable cables are cables that have connectors on both ends.
One end goes into your headphone cups, 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. With a detachable cable, Sony WH 1000XM4 too can use alternative cables and if the cable is pulled, it will pop out instead of breaking.
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 microfractures 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. Sony WH 1000XM4 comes with a 1.2meters cable.
Almost any cable should be fine in sound quality If you're looking at lengths up to 2 - 3 meters. 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 1000XM4 with this design offer potential for maximum bass and loudness levels. Sony WH CH720N have stereo speakers, devices with stereo speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better listening experience. The Sony WH 1000XM4 also have stereo speakers
Active noise cancellation uses more advanced technology to actively counter noise.
How it works, it listens to the sound pattern outside and inside the earbud and then generates a mirror signal 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 hence "diluting" the 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.
Sony WH 1000XM4 too have active noise cancellation making both devices ideal for plane rides and morning commutes. Each may work with different noise cancellation modes, pick the setting, mode, or noise cancellation type that you prefer for commute or that enhances your relaxation time. Passive Noise Cancellation uses well-designed ear cups to seal out environment 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. Both of these devices have passive noise reduction which means that also the Sony WH 1000XM4 isolates you from ambient noise instead of actively using technology to cancel it 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. Sony WH 1000XM4's lowest frequency is at 4Hz, this means that
Sony WH CH720N got a juicier bass than the Sony WH 1000XM4

Sony WH 1000XM4 got a clearer and crispier treble than the Sony WH CH720N
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 a way of getting 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. Sony WH 1000XM4's sound pressure level measurement is 105dB/mW. 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. Sony WH 1000XM4 driver unit is 40mm in diameter,
making them have a larger driver unit than that of Sony WH CH720N by 10mm
, many people have a misconception that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty reproducing high frequencies so it's true that, larger drivers can generate louder sound, but this does not mean that they deliver better sound.
Defined as the device's resistance to the electromagnetic current, as electricity flows through a wire, it experiences 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.
Sony WH 1000XM4's impedance is 16Ohms. The impedance of earbuds is the electrical resistance of the driver unit present on the inside. 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
Sony WH 1000XM4's battery life is 30 hours. Each time you recharge your headphones, they get a little less listening time.
The effect is barely noticeable at first. But over a few years, you may find that your device, no longer plays for long like it used to. 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. Sony WH 1000XM4 takes 3 hours to fully charge the battery
