In the professional audio sector, headphones are used in live situations by disc jockeys with a DJ mixer, and sound engineers for monitoring signal sources. In radio studios, DJs use a pair of headphones when talking to the microphone while the speakers are turned off to eliminate acoustic feedback while monitoring their own voice. In studio recordings, musicians and singers use headphones to play or sing along to a backing track or band. In military applications, audio signals of many varieties are monitored using headphones.
Garbage in = Garbage out (GIGO) is a popular phrase used to emphasize the importance of a good source. This can be the soundcard in your laptop, the quality of your portable audio player, or the CD player you’re using for music listening. Those fall into the “Source” category. The better your source is, the better the sound will be at the headphone end. This is why we are seeing more and more audiophile digital audio players (audiophile DAPs). They are expensive but they sound good.

Hearing risk from headphones' use also applies to workers who must wear electronic or communication headsets as part of their daily job (i.e., pilots, call center and dispatch operators, sound engineers, firefighters, etc.) and hearing damage depends on the exposure time. The National Institute for Occupational Safety and Health (NIOSH) recommends sound exposure not exceed 85 dB(A) over 8 hour work day as a time-weighted average. NIOSH uses the 3-dB exchange rate often referred to as "time-intensity tradeoff" which means if sound exposure level is increased by 3 decibels, the duration of exposure should be cut in half. NIOSH published several documents targeted at protecting the hearing of workers who must wear communication headsets such as call center operators, firefighters, and musicians and sound engineers.
While Apple’s AirPods get a lot of attention for how well they work with other Apple products, there’s actually a more affordable option that’s just as tightly integrated: the Beats BeatsX Earphones. Apple owns the Beats brand, and it’s built the BeatsX earphones with the same W1 chip that’s in the AirPods. That means that the user experience is virtually identical – iOS makes it super easy to pair them with any iPhone or iPad. Our favorite part is they have a Fast Fuel feature, so when your battery is low, plugging them in for five minutes provides two hours of talk time. We’re also big fans of the COWIN E7 Headphones. They’re wireless, they’ve got on-board noise cancellation, and they can last up to 30 hours on a single charge. The E7’s have an impressive spec sheet for any price point, but the fact that they’re so affordable makes them an even better value. If you’re looking for affordable over-the-ear headphones that don’t make any compromises, this is the pair to get.
Earbuds have small speakers that rest on the ear canal of the wearer. These are usually much less expensive than on-ear and over-ear headphones and reproduce the sound well. However, outside sounds, such as traffic or power tools, can get past the earbuds and interfere with your enjoyment. Earbuds also don't stay in place very well if the wearer is moving much, such as exercising. These also are lower fidelity than on-ear and over-ear headphones.
