The main causes of poor performance with these earpieces are low diaphragm excursion, nonlinearity, in-band resonance and the very short horn shape of the earpiece casing. The resulting sound is very tinny and lacking in bass. Modern headphones use electromagnetic drivers that work similarly to speakers, with moving coils or moving iron cores ...
After 60 long minutes, he takes the devices out of the water and makes sure that everything works properly, making us think that maybe they are secretly waterproof.

Headsets with headbands going over the back of the user's neck are known as backwear-headsets or behind-the-neck headsets. Headsets worn over the ear with a soft ear-hook are known as over-the-ear headsets or earloop headsets. Convertible headsets are ...
The iPhone Stereo Headset was introduced in 2007 and was bundled with the original iPhone and iPhone 3G, and featured a control capsule in-line with the left earbud's wire with a microphone and a single button, actuated by squeezing the unit, which can be programmed to control calls, presentations, music and video playback, launch Siri, or take pictures with the Camera application.
Connecting a low-impedance load such as a loudspeaker (usually 4 to 8 Ω) to a line out will essentially short circuit the output circuit. Such loads are around 1/1000 the impedance a line out is designed to drive, so the line out is usually not designed to source the current that would be drawn by a 4 to 8 ohm load at normal line out signal ...
A power bank can be a lifesaver for a busy person. Use it to charge phones, tablets, e-readers, headphones and much more. This one by Anker has over 20,000mAh power reserve and provides over four ...
While a loudspeaker must use a relatively large (often 15" or 18") speaker driver to reproduce low frequencies, headphones can accurately reproduce bass and sub-bass frequencies with speaker drivers only 40-50 millimeters wide (or much smaller, as is the case with in-ear monitor headphones). Headphones' impressive low-frequency performance is ...
