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, Sennheiser HD 660S2 are one of those.
With a detachable cable, Master & Dynamic MW65 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, Sennheiser HD 660S2'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.
Headphones that are designed to allow air to pass through their ear cups from the rear of the speaker driver unit are known as open-back. This design provides a very natural and accurate sound, Sennheiser HD 660S2 have this kind of design which means that resonances and low-frequency that tend to build up caused by the rear enclosure are no longer a concern.
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. Sennheiser HD 660S2 comes with a 1.8meters cable.
Master & Dynamic MW65 comes with a 1.5meters 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 Sennheiser HD 660S2 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.
Master & Dynamic MW65 with this design offer potential for maximum bass and loudness levels.
Sennheiser HD 660S2 have stereo speakers, devices with stereo speakers deliver sound from independent channels on both left and right sides, this creates a richer sound and a better listening experience.
Both Master & Dynamic MW65 and Sennheiser HD 660S2 have stereo speakers
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 zero 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.
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 Sennheiser HD 660S2 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.
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. Sennheiser HD 660S2's lowest frequency is at 8Hz, the lower the low-frequency response, the stronger and juicier the bass.
Master & Dynamic MW65's lowest frequency is at 20Hz, this means that Master & Dynamic MW65 got a juicier bass than the Sennheiser HD 660S2
High frequency response measures if and how well an audio component reproduces high audible frequencies and if it makes any changes to the signal while at it. Sennheiser HD 660S2's highest frequency is at 41500Hz, the higher the high-frequency response, the clearer and crispier the treble.
Master & Dynamic MW65's highest frequency is at 20000Hz, this implies that Sennheiser HD 660S2 got a clearer and crispier treble than the Master & Dynamic MW65
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, Sennheiser HD 660S2's measurement is 104dB/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. Sennheiser HD 660S2 driver unit is 38mm in diameter, bigger drivers are more powerful and can produce better bass.
Master & Dynamic MW65 driver unit is 40mm in diameter, making them have a larger driver unit than that of Sennheiser HD 660S2 by 2mm , 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 yeah, larger drivers are capable of generating louder sound, but this does not mean that they produce better sound.
Defined as the device's resistance to the electromagnetic current, when electricity flows through a wire, it experiences electrical resistance that counters the flow of current. The resistance of a conductor is measured in ohms. Sennheiser HD 660S2's impedance is 300Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.
Master & Dynamic MW65's impedance is 32Ohms. The impedance of earbuds is the electrical resistance of the driver unit present on the inside.
Neodymium magnets if used in audio devices produce a higher sensitivity and substantial sound output using less power to do so. 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.
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. Master & Dynamic MW65's battery life is 24 hours
Master & Dynamic MW65 have a battery level indicator, an indicator shows you when the device has a low battery. The battery indicator lights show the charging status of your headphones.
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. Master & Dynamic MW65's battery can be recharged and used over again.
Master & Dynamic MW65 can be used wirelessly, wireless devices allow users more freedom of movement.
Bluetooth is a wireless technology standard that allows data transfers between devices placed in close proximity, using short-wavelength, ultra-high frequency radio waves. Master & Dynamic MW65 has a v4.2
Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances. The Master & Dynamic MW65 can connect at a 20meters 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.
Sennheiser HD 660S2 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.
Master & Dynamic MW65 too have this kind of connector
Master & Dynamic MW65 have only 2 microphones, more microphones result in better sound quality and enable the device to filter out background noise.
There is a control panel on the Master & Dynamic MW65 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.
Master & Dynamic MW65 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 Sennheiser HD 660S2 come with their own special case or pouch, which is useful for safe transportation.
Master & Dynamic MW65 too have a travel bag or case included.
