Today’s EIO post is on our newest headset: the SYBA CL-AUD63032 3.5mm Connector Circumaural Headset.

Why over-the-ear-headphones

Over-the-ear headphones that are large enough tend to provide sound that can be reminiscent of a good pair of speakers. Many over-the-ear headphone enthusiasts are so satisfied with the quality of audio from their high-end cans that they don’t even own a pair of hi-fi speakers.

What are Circumaural (around-ear headphones)?

These types are the largest out there and are generally designed to fit around your earlobes. Of course, some versions of circumaural cans merely cup the back of your ear instead of completely surrounding your ear, but they still work the same way. The idea of around-ear-type headphones is to be able to accommodate larger drivers which can make a musical performance sound more realistic. The larger earcups also allow manufacturers to position the drivers at some distance from your ear, implement multiple drivers and angle the drivers in various ways to affect sound quality. Having earcups instead of earpads also ensures that they’re more comfortable when worn for longer listening sessions.

Today’s Eio post is on headphones.

With the explosion of handheld electronic devices, such as ipods, mp3 players, and cellphones, headphones are everywhere and come in many different types.

With the intention of being held in place close to one’s ears to hear the audio, headphones are a pair of miniaturized and wearable loudspeakers.

Different Types of Headphones

Dynamic Headphones

Dynamic headphones are the standard headphones, which work similar to miniature speakers. The audio signal reaches the headphones through a connection to a standard jack. The electrical signal creates a rapid vibration which creates vibratory sound waves which are picked up by our eardrums and translated into sound.

Dynamic headphones come in many variations, such as behind the neck, over the head, sport, made for Stereo/DJ, even noise cancelling.

“Purple / white colors match your taste. The lightweight design ensures excellent comfort for hours of use. Compatible with any device that features a 3.5mm outputs.”

Infrared Headphones

These are cordless headphones which utilize infrared lights to transmit sound from the audio’s sender to the headphone’s receiver. These have advantages because cords don’t get tangled nor caught on sharp edges. The drawback is if something blocks the sender/receiver signal, the sound quality will weaken.

With Koss’ wireless headphones, “you can roam up to 250 feet in any direction from your music source without missing a beat. With an AC adapter, infrared transmitter, receiver and stereophones, these headphones are ideal for home theater and video. The behind-the-ear design of the headphones maximize your comfort for extended wearing periods. What better way to enjoy both the comfort of your home and your favorite music! The Koss HB60 Headphones feature a dynamic element for extended frequency response and can connect to most audio and video systems. The headphone require two AAA batteries.”


Instead of resting on the head as dynamic headphones do, earbuds sit inside the opening of the ear. They are lightweight, portable, and sometimes unnoticeable.
