Sonic Electronix, one of the leaders in car audio, recently visited Harman, the premium global audio and infotainment group, at their research and development locations in Northridge, California and Detroit, Michigan. On-Ear: This type of headphone involves the speaker sitting gently on the ear without going in the ear or sealing it off.
Earbuds means that the right and left sides of the headphones are separated and will fit securely into the ear. Over the Head headphones mean that the right and left speakers are connected with a support that goes over the head and rests on top. Specifically ForSome headphones can use an IR Transmitter in your vehicle, while some can be plugged into your media device and be used on the go or at home.
Home Hi-Fi: These audiophile headphones are engineered to produce high fidelity and accurate audio.
Kids: Feature noise limiting technology so that your little ones don't damage their ears listening to music too loud. On-the-Go: On-the-go headphones are lightweight and often fold up for easy storage and portability. Open: Have ports that allow air through the back of the diaphragms, enabling the headphones to sound like the music is coming from an outside source. Device Controls & CompatibilityRefers to the devices the in-line controls are compatible with. Bluetooth means that the audio signal is transmitted from your device to the headphones via a Bluetooth connection. Corded or Bluetooth means that the headphones can be used as corded headphones or as Bluetooth headphones.
Volume AdjustmentVolume Adjustment means that the headphone (independent of the source) can adjust the playback volume.


A balanced armature driver uses a coil wrapped around an armature which is held in between two magnets until it is stimulated by an electrical current.
Electrostatic drivers are made up of an extremely thin membrane, usually a coated PET film, stretched between two metal plates. A planar magnetic driver is made up of a large membrane suspended between two sets of oppositely aligned magnets. ImpedanceThe opposition to electric current, a higher impedance means a higher electrical resistance.
SensitivityAn efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. Frequency ResponseThe range of frequencies the speaker will reproduce (lowest frequency to the highest). Compact and easy to travel with, these noise-canceling headphones will make a crowded airplane, subway or plaza seem downright peaceful, while delivering powerful sound directly to your ears.
The purpose of these visits was to utilize and combine the powerful brand of Harman and the industry leading knowledge behind Sonic Electronix to begin working together on developing future car audio projects.
They have an input in one or both earcups for use as a corded headphone while they also have a built-in battery for use as Bluetooth wireless headphones. Many headphones and ear buds have in-line volume control, which allows adjusting the audible volume from a switch on the headphones cord. Most headphones are built from some combination of plastic and metal to give you a durable pair of headphones.
Ear cushions and earbuds are available in a variety of materials, ranging from basic rubber eartips to plush leather ear cushions intended for maximum comfort. Some fitness trackers are water resistant and can be used while swimming, while others are only splash proof or should not be used near the water.


When stimulated, this armature is magnetized which causes it to rotate one way or the other around a pivot point which moves the diaphragm to create sound. They feature a permanent magnet, usually neodymium, a voice coil and a conical diaphragm to drive your music.
An electrical signal is applied to the metal plates to create an electrical field which, depending on its polarity, draws the speaker diaphragm toward one of the plates which forces air through the perforations in the diaphragm which generates the sound wave. The higher the number, the more efficient the speaker and the louder it will play with the same input power. Audiophile headphones produce genuinely outstanding sound quality as well as extraordinary build quality, components and comfort. A premium hard case is included to protect your iPhone or iPod when youa€™re on the go, and an in-line microphone lets you answer a call as easily as listening to a song. These mics can be used for music devices like iPods, for Smartphones to make and receive calls, or for gaming purposes. Balanced armature driver headphones are generally earbuds and can have multiple drivers in each earbud. A dynamic headphone driver looks pretty much identical to any typical home theater speaker. Lightweight and comfortable, these in-ear headphones deliver the detailed, studio-quality sound that AKG engineering has provided top musicians for over 65 years.
Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker.
