Each person must find best headphones for listening to their favorite music. And now many emerging products that are able to provide good quality. However, of the many products offered by the best headphones which are in accordance with our criteria?
Here we try a little to discuss anything that meets the criteria as the best headphones.

Headphones are a pair of small loudspeakers which are designed to be held in place close to a user's ears. Headphones have wires which allow them to be connected to a signal source such as an audio amplifier, radio, CD player, or portable media player. They are also known as stereophones or, colloquially, cans. The in-ear versions are known as earphones or earbuds. In the context of telecommunication, the term headset is used to describe a combination of headphone and microphone.

Impedance
Headphones are available with low or high impedance measured at 1 kHz. Low-impedance headphones are in the range 75 to 150 ohms and high-impedance headphones are about 600 ohms.[4] High impedance headphones have been popular among tube amplifier aficionados,[citation needed] and in ...
... classroom or studio situations requiring many headphones connected in parallel to the same source. Low impedance headphones yield a louder sound from a standard headphone jack, and require less voltage to achieve a target sound pressure level—an important consideration for portable electronics. So, you can get your best headphones by considering the Impedance.

Sensitivity also affects the best headphones criteria.
Sensitivity is a measure of a transducer's output when driven with a specific reference input. Headphone manufacturers often loosely use the term "efficiency" where sensitivity should be used. Headphone efficiency (power in/power out) is a type of sensitivity, but efficiency is usually not an important characteristic to measure for headphones .

Types
The particular needs of the listener determine the choice of best headphones. The need for portability indicates smaller, lighter headphones but can mean a compromise in fidelity. Headphones used as part of a home hi-fi do not have the same design constraints and can be larger and heavier. Generally, headphone form factors can be divided into four separate categories: circumaural, supra-aural, earbud, and in-ear.

Ambient noise reduction
Interference from external sound can be reduced either by active noise cancellation, or by attentuating noise getting into the ear. The two headphone types that do this attenuation best are in-ear canal headphones and closed-back headphones (both circumaural and supraural). Open-back and earbud headphones provide some noise isolation as well, but to a much lesser extent than the closed-back and in-ear. Typically closed-back headphones block 8 to 12 dB and in-ears anywhere from 10 to 15 dB. So if you wanna know all about this, please go to Best Headphones Info
