Frequency response: Frequency-response specifications in full-size loudspeakers are generally pretty useless in predicting sound quality, but headphone frequency-response numbers are even worse. Manufacturers have routinely exaggerated frequency-response figures to the point that they're irrelevant. Even the flimsiest, cheap headphones routinely boast extremely low bass-response performance --15Hz or 20Hz -- but almost always sound lightweight and bright. Generally, bass buffs will be happier sticking with larger 'phones.
If you won’t compromise on sound quality—and you’re willing to pay for it—the Bang & Olufsen Beoplay E6 may be for you. It doesn’t come cheap, but the Beoplay E6 is one of the best portable wireless models we’ve ever tested. In addition to sound quality, it has design perks including magnets that clip the earpieces together (and automatically turn the headphones off) for easy transport, a braided cable for added durability, and water resistance, according to the manufacturer.
Wired headphones are attached to an audio source by a cable. The most common connectors are 6.35 mm (¼″) and 3.5 mm phone connectors. The larger 6.35 mm connector is more common on fixed location home or professional equipment. The 3.5 mm connector remains the most widely used connector for portable application today. Adapters are available for converting between 6.35 mm and 3.5 mm devices.
Headphones (or head-phones in the early days of telephony and radio) traditionally refer to a pair of small loudspeaker drivers worn on or around the head over a user's ears. They are electroacoustic transducers, which convert an electrical signal to a corresponding sound. Headphones let a single user listen to an audio source privately, in contrast to a loudspeaker, which emits sound into the open air for anyone nearby to hear. Headphones are also known as earspeakers, earphones[1] or, colloquially, cans.[2] Circumaural ('around the ear') and supra-aural ('over the ear') headphones use a band over the top of the head to hold the speakers in place. Another type, known as earbuds or earpieces[1] consist of individual units that plug into the user's ear canal. A third type are bone conduction headphones, which typically wrap around the back of the head and rest in front of the ear canal, leaving the ear canal open. In the context of telecommunication, a headset is a combination of headphone and microphone.
Noise cancelation for kids? Doesn’t that mean they’ll ignore their parents even more often than they already do? Perhaps, but it’s a risk worth taking if it means your kids’ hearing will be protected over the long-term. That’s exactly the premise behind the Puro PuroQuiet headphones. Not only are they wireless and great-sounding, but they also come equipped with a software limiter that keeps the volume at or below 85dB, which is considered the maximum volume that children should be exposed to for prolonged periods. The noise-canceling feature means they’ll actually be able to listen to lower (therefore safer) volumes.
The thermoacoustic effect generates sound from the audio frequency Joule heating of the conductor, an effect that is not magnetic and does not vibrate the speaker. In 2013 a carbon nanotube thin-yarn earphone based on the thermoacoustic mechanism was demonstrated by a research group in Tsinghua University.[22] The as-produced CNT thin yarn earphone has a working element called CNT thin yarn thermoacoustic chip. Such a chip is composed of a layer of CNT thin yarn array supported by the silicon wafer, and periodic grooves with certain depth are made on the wafer by micro-fabrication methods to suppress the heat leakage from the CNT yarn to the substrate.[citation needed]
Music keeps me energized all day (and into the night) at work — 70% electronica/dance/DNB, 20% rock, 5% hip hip and 5% other/classical — but I’m tired of low-quality sound and I’m ready to put my money where my ears are.  I want to buy a USB DAC + Headphone amp, buy headphones (or, per your recommendation, to buy 2 pair) to complement the amp and my choice of music, and get great desktop sound for around $350.

Choosing the right headphones makes it possible for you to hear your music the way the artist who made it intended, with all the nuances from the right bass and treble levels so you can hear every drum beat and guitar strum. Not all headphones are ideal for everybody and are a matter of personal taste, comfort and style. Find the ideal pair of headphones to use with your mobile device, stereo or computer, available at our Every Day Low Prices, and get your groove on.
