By sweat resistance we mean that the wireless earbuds are protected in the presence of low-pressure water jets at any angle, this is determined by the IP Rating of the earbuds. Based on the ingress protection rating of the Sony WH CH520 they do have sweat resistance
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.
On-ear headphones have smaller earpads that sit on top of your ears, this Sony WH CH520 comfortably rests on top of your outer ears. As it doesn't block out everything from the outside world, it's preferred in places like office environments and recommended for outdoor activities.
Sony WH CH720N have stereo speakers, devices with stereo speakers deliver sound from separate channels on both left and right sides, creating a richer sound and a better listening experience.
The Sony WH CH520 also have stereo speakers
Active noise cancellation uses more advanced technology to actively counter noise. How it works, it detects and analyzes the sound pattern outside and inside the earbud 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 zero 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.
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.
Both of these devices have passive noise reduction which means that also the Sony WH CH520 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 component 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 CH520's lowest frequency is at 20Hz, this implies that both devices produce equal bass
High frequency response measures if and how well a particular audio device reproduces high audible frequencies and if it changes to the signal while at it. Sony WH CH720N's highest frequency is at 20000Hz, the higher the high-frequency response, the clearer and crispier the treble.
Sony WH CH520's highest frequency is at 20000Hz, this implies that both devices produce equal 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 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.
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.
Defined as the device's resistance to the electromagnetic current, as electricity flows through a conductor, 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.
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 CH520's battery life is 40 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 CH520 takes 3 hours to fully charge the battery
