A breakdown of the review per specifications



Master & Dynamic MW65 245g
Sony WH CH520 147g

Sony WH CH520 have a weight of 147g, 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 better because lighter devices are more comfortable to carry.

Has A Detachable Cable

Master & Dynamic MW65
Sony WH CH520

Detachable cables are cables that have connectors on both ends. One end goes into your headphone cups, while the other end is inserted into an audio source. Some new headphones, and not just the expensive ones, are coming with detachable cables, Master & Dynamic MW65 are one of those.

Has A Tangle Free Cable

Master & Dynamic MW65
Sony WH CH520

Twisted headphone cables can be a great source of annoyance and inconvenience, Sony WH CH520'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.

Sweat Resistance

Master & Dynamic MW65
Sony WH CH520

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

Cable Length

Master & Dynamic MW65 1.5meters
Sony WH CH520

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. Master & Dynamic MW65 comes with a 1.5meters cable.

Has An Over-The-Ear Foam

Master & Dynamic MW65
Sony WH CH520

Over-ear headphones have larger earpads that fit around your entire ear Master & Dynamic MW65 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.

Has An On-Ear Foam

Master & Dynamic MW65
Sony WH CH520

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.

Has Stereo Speakers

Master & Dynamic MW65
Sony WH CH520

Sony WH CH520 have stereo speakers, what this means is that Sony WH CH520's speakers deliver sound from separate channels on both left and right sides, this creates a richer sound and a better listening experience.

Both Master & Dynamic MW65 and Sony WH CH520 have stereo speakers

Sound Quality

Has Active Noise Cancellation (Anc)

Master & Dynamic MW65
Sony WH CH520

Active noise cancellation uses more advanced technology to reduce unwanted ambient sounds. 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 0 resulting in a reduced level of noise.

Master & Dynamic MW65 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.

Has Passive Noise Reduction

Master & Dynamic MW65
Sony WH CH520

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 CH520 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 Master & Dynamic MW65 isolates you from ambient noise instead of actively using technology to cancel it out.

Lowest Frequency

Master & Dynamic MW65 20Hz
Sony WH CH520 20Hz

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 CH520's lowest frequency is at 20Hz, the lower the low-frequency response, the stronger and juicier the bass.

Master & Dynamic MW65's lowest frequency is at 20Hz, this implies that both devices produce equal bass

Highest Frequency

Master & Dynamic MW65 20000Hz
Sony WH CH520 20000Hz

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 CH520's highest frequency is at 20000Hz, the higher the high-frequency response, the clearer and crispier the treble.

Master & Dynamic MW65's highest frequency is at 20000Hz, this means that both devices produce equal treble

Driver Unit Size

Master & Dynamic MW65 40mm
Sony WH CH520

The driver unit is basically a mini speaker that produces sound in the device, its size dictates the loudness of the headphone. Master & Dynamic MW65 driver unit is 40mm in diameter, bigger drivers are more powerful and can produce better bass.


Master & Dynamic MW65 32Ohms
Sony WH CH520

Defined as the device's resistance to the electromagnetic current, when electricity flows through a conductor, it experiences electrical resistance that counters the flow of current. The resistance of a conductor is measured in ohms. Master & Dynamic MW65's impedance is 32Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.

Has A Neodymium Magnet

Master & Dynamic MW65
Sony WH CH520

Neodymium magnets if 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 Master & Dynamic MW65 have this type of magnet.


Battery Life

Master & Dynamic MW65 24hours
Sony WH CH520 40hours

If your headphones play wirelessly, cancel ambient noise, or enhance your listening experience with active features, their battery life will reduce over time.
