Sony WH 1000XM4 have a weight of 254g, these weigh below 320g, which we consider as the highest average a headphone should weigh for comfort during long use. We take in account a lower weight better because lighter devices are more comfortable to move with. 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 1000XM4 are one of those. Ingress protection ratings refer to the level of protection offered by an electrical enclosure, against solids and liquids.
In the format of IPXX, 'X' represent a number The first number of the IP rating refers to protection against solids say dust, while the second refers to protection against liquid.
Having a value of IPX4, the Sony WH 1000XM4's rating is read as, the first value of X denotes that no data available to specify a protection rating, and the second value of 4 means that they can withstand low pressure spray similar to that of a shower head when tilted at 180° for 10 minutes. Sony WH 1000XM4 are foldable, which makes them more portable.
Foldable headphones are easier to transport and take up less storage space. 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 1000XM4 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 1000XM4 comes with a 1.2meters cable. Over-ear headphones have larger earpads that fit around your entire ear Sony WH 1000XM4 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 have stereo speakers, devices with stereo speakers deliver sound from separate channels on both left and right sides, this creates a richer sound and a better listening experience. Active noise cancellation uses more advanced technology to actively counter noise.
How it works, it listens to 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 zero hence "diluting" the noise.
Sony WH 1000XM4 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 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 1000XM4 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 1000XM4's lowest frequency is at 4Hz, the lower the low-frequency response, the stronger and juicier the bass. High frequency response measures if and how well an audio device reproduces high audible frequencies and if it changes to the signal while at it.
Sony WH 1000XM4's highest frequency is at 40,000Hz, 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 1000XM4's measurement is 105dB/mW.
Devices with a higher sound pressure level are generally louder when supplied with any given audio source. The driver unit is the component that produces sound in the device, its size dictates the loudness of the headphone. Sony WH 1000XM4 driver unit is 40mm 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 1000XM4's impedance is 16Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.
Neodymium magnets when used in audio devices produce a higher sensitivity and substantial sound output while using less power. They can help produce music at quite a high sound pressure level, SPL, with the use of high magnetic flux. The Sony WH 1000XM4 have this type of magnet.
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 1000XM4's battery life is 30 hours
