JLab's affordable, wireless sport buds also offer great value for the money. They have a very comfortable over-ear clip and Cloud Foam tips, and are IP66 rated. (I ran in the rain with these with no problem.) They have a crisp, clear Bluetooth 5.0 connection and decent 6-hour battery life. I can wear these for up to two weeks of working out without having to recharge the case, which also has its own convenient included charging cable. As is typical with JLab's workout buds, the signature EQ is bass-heavy and upper ranges can sometimes sound a little frizzy. But as I'm running or hiking, I sometimes forget I'm even wearing them.
The moving coil driver, more commonly referred to as a "dynamic" driver is the most common type used in headphones. It consists of a stationary magnet element affixed to the frame of the headphone, which sets up a static magnetic field. The magnet in headphones is typically composed of ferrite or neodymium. A voice coil, a light coil of wire, is suspended in the magnetic field of the magnet, attached to a diaphragm, typically fabricated from lightweight, high-stiffness-to-mass-ratio cellulose, polymer, carbon material, paper or the like. When the varying current of an audio signal is passed through the coil, it creates a varying magnetic field that reacts against the static magnetic field, exerting a varying force on the coil causing it and the attached diaphragm to vibrate. The vibrating diaphragm pushes on the air to produce sound waves.
I was pleasantly surprised by what headphone company Status is able to offer for the money. The BT Structure are its wired sport headphones—IPX5 rated to protect against sweat, with a comfortable over-ear clip. They also have a dual-driver system, which is unusual for sporty headphones in this price range. Most sports headphones tend to emphasize the bass, but the BT Structure sounded very balanced and expansive—the highs of "This Is What You Came For" sparkled against the heavy bass beats. The 10+ hours of battery life is pretty spectacular, too.
Although some headphones available are wired, many more are available that are wireless, and use Bluetooth to enable your music to be heard, even if the stereo or other device is several feet or even a few rooms away. Wired headphones deliver superior sound quality to wireless and Bluetooth because there's no chance of picking up interference from other devices, which sometimes happens with wireless headphones. In addition, wired headphones have no batteries to power them, so there's no chance of interruption should the batteries wear out.
