Using headphones at a sufficiently high volume level may cause temporary or permanent hearing impairment or deafness. The headphone volume often has to compete with the background noise, especially in loud places such as subway stations, aircraft, and large crowds. Extended periods of exposure to high sound pressure levels created by headphones at high volume settings may be damaging to hearing;[25][26] Nearly 50% of teenagers and young adults (12 to 35 years old) in middle and high income countries listen to unsafe levels of sound on their personal audio devices and smartphones.[27] however, one hearing expert found in 2012 (before the worldwide adoption of smartphones as the main personal listening devices) that "fewer than 5% of users select volume levels and listen frequently enough to risk hearing loss."[28] The International Telecommunication Union recently published "Guidelines for safe listening devices/systems" recommended that sound exposure not exceed 80 decibels, A-weighted dB(A) for a maximum of 40 hours per week.[29] The European Union have also set a similar limit for users of personal listening devices (80 dB(A) for no more than 40 hours per week) and for each additional increase of 3-dB in sound exposure, the duration should be cut in half (83 dB(A) for no more than 20 hours, 86 dB(A) for 10 hours per week, 89 dB(A) for 5 hours per week and so on. Most major manufactures of smartphones now include some safety or volume limiting features and warning messaging in their devices.[30][31] though such practices have received mixed response from some segments of the buying who favor the personal choice of setting their own volume levels.

Audiophiles generally agree that if you’re passionate about music, and you have a listening space that is relatively free of outside sounds, nothing beats a really good set of open-back headphones. As far as we’re concerned, you won’t find a set of open-back headphones that manage to combine superb sound quality and a reasonable price than the Sennheiser HD6XX/HD650. To be clear, these are not exactly the same models. The HD6XX is a run of the HD650 with a lower price from Massdrop, and a few physical changes, but when it comes to their audio chops, they’re identical.


I’m a former Mixer and DJ and I’d highly recommend the Beyer T1 for mixing. It is not absolutely flat, but it is an all around proper Audio Technicians Headphone. For flat response, I might eyeball the HD800 but the low end might not be the best if you are often mixing tracks with solid low ends. Flat might not always be the best option ( my opinion ). If you need to mix heavy bass tracks, it is better to have a headphone that responds better to low end EQ and is generally accepted as a more well rounded headphone.
Headphones connect to a signal source such as an audio amplifier, radio, CD player, portable media player, mobile phone, video game console, or electronic musical instrument, either directly using a cord, or using wireless technology such as Bluetooth, DECT or FM radio. The first headphones were developed in the late 19th century for use by telephone operators, to keep their hands free. Initially the audio quality was mediocre and a step forward was the invention of high fidelity headphones.[3]

AAC has some advantages when it comes to latency, but we recommend avoiding this if you care about audio quality. We found high levels of noise and lower than average frequency cutoffs—both unacceptable to audiophiles and younger listeners. Though the sound isn’t as bad as some may make it out to be, the shortcomings are noticeable to the human ear at normal listening volumes.
A. It can be difficult, so buy earbuds that include silicone tips in multiple sizes. Everyone’s ears are unique, so most earbud manufactures include small, medium, and large silicone tips that you can easily swap out. If you want a particularly snug fit, consider getting third-party earphone tips made of memory foam, which will always adjust to the contours of your ears.
While the data signal containing Bluetooth audio is compressed, headphone and earphone manufacturers have found ways to enhance the signal to compensate for its deficiencies in a way that even audiophiles can appreciate. We've included some wireless options here, but if you're really keen on cutting the cord, check out The Best Wireless Headphones. And if you want to go completely wireless (with no cord at all connecting the two earpieces), check out The Best True Wireless Headphones—just keep in mind these are about as far from over-ear headphones as you can get.
The Elite Active 65t come with three sets of silicone tips and feature an ergonomic design that guarantees a good seal, which is a big reason we prefer them to other true wireless models. With outstanding comfort and excellent passive noise isolation, you get the most out of every note, and you can also lower the volume for less ear strain. Overall sound quality is solid, and sound comes through clear and balanced, with a punchy bass response and a surprisingly dynamic treble range.
The Sony noise-cancelling headphones are a tiny miracle. They’re great at blocking the outside world, so you’ll hear your music and nothing else – at a price point that’s less than $50. Wired headphones can be a tough sell for those who’ve grown accustomed to wire-free listening, but if you’re all right with a wired connection, this pair is an easy choice.
Headphones may be used with stationary CD and DVD players, home theater, personal computers, or portable devices (e.g., digital audio player/MP3 player, mobile phone). Cordless headphones are not connected to their source by a cable. Instead, they receive a radio or infrared signal encoded using a radio or infrared transmission link, such as FM, Bluetooth or Wi-Fi. These are powered receiver systems, of which the headphone is only a component. Cordless headphones are used with events such as a Silent disco or Silent Gig.

Ok, it’s been a month and a lot of new experience. I’ve auditoned ATH M-50 (clamp’s too tight; they sweat my ears just from few minutes of exposure) and Senn HD 600 (the velour pad is amazingly comfortable & size is ok). So, long story short, now I can refine my search to: circumaural&non-pleather/foam pads, which brought me to Senn HD 439 (cloth) & 518 (velour).
In-ear headphones are like earbuds but are an upgrade to them. These headphones fit into the wearer's ear canal and stay in place with the use of foam or rubber tips. These tips are available in custom sizes so they can fit each individual wearer. When a proper fit's achieved, in-ear headphones reduce outside noise and deliver sound quality at about the same level as over-ear and on-ear headphones.
