The Sennheiser HD 660S2 have a weight of 260g, 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 transport.
The Sennheiser HD 560S, at 240g are lighter than the Sennheiser HD 660S2 with a difference -20g
Detachable cables are cables that have connectors on both ends. One end goes into your headphone earpieces, 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, Sennheiser HD 560S 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 microfractures in the copper wires, affecting sound quality, or
rendering your headphones defective.
Sennheiser HD 560S too have a cable designed to help prevent tangles.
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.
The Sennheiser HD 560S also have an open-back design such headphones are designed with vents or perforations at the back of the ear cups.
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.
Sennheiser HD 560S comes with a 3meters 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.
Sennheiser HD 560S with this design offer potential for maximum bass and loudness levels.
Sennheiser HD 660S2 have stereo speakers, what this means is that Sennheiser HD 660S2's speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better listening experience.
The Sennheiser HD 560S also have stereo speakers
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 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 Sennheiser HD 560S isolates you from ambient noise instead of actively using technology to cancel it out.
Low-frequency response measures if and how well an audio device 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.
Sennheiser HD 560S's lowest frequency is at 6Hz, this means that Sennheiser HD 660S2 got a juicier bass than the Sennheiser HD 560S
High frequency response measures if and how well a particular audio component reproduces high audible frequencies and if it makes any changes to the signal on the way through. Sennheiser HD 660S2's highest frequency is at 41500Hz, the higher the high-frequency response, the clearer and crispier the treble.
Sennheiser HD 560S's highest frequency is at 38000Hz, this means that Sennheiser HD 660S2 got a clearer and crispier treble than the Sennheiser HD 560S
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, 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.
Sennheiser HD 560S's sound pressure level measurement is 110dB/mW.
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.
Sennheiser HD 560S driver unit is 38mm in diameter, making both Sennheiser HD 560S, and Sennheiser HD 660S2 similar in how loud their sound gets , as many tend to believe that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty reproducing high frequencies so yes, 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 faces electrical resistance that counters the flow of current. The resistance of a wire 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.
Sennheiser HD 560S's impedance is 120Ohms. The impedance of earbuds is the electrical resistance of the driver unit present on the inside.
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.
Sennheiser HD 560S too have this kind of connector
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.
