Enclosed-Ear: Usually are found on the larger headphones. They rest on top of the ear and have padding for comfort, as well as enclosing the ear to the speaker. This type of headphone helps to filter out surrounding noise.

On-Ear: This type of headphone involves the speaker sitting gently on the ear without going in the ear or sealing it off.

Headphone Connection
This is how the headphones connect to the audio source.

Corded means that the headphones use a cord to transfer the audio signal.

Wireless means that the audio signal is transmitted wirelessly to the headphones.

1/4" Stereo Jack Adapter

10 times better!

October 10, 2013

I tried almost every headphones before I ordered this one. I'm fully satisfied with it. This headphone has the best sound I've ever heard.
The only little problem with it is the wireless adapter stopped working properly, and i can not use it for my iphone, because it has contact failure, but if i dont move it, it works well, so i still can use it with my TV.

They deserve the price

May 6, 2013

I ordered SyncBy50 headphones around 6 months ago, I was afraid that it wasn't worth the 280$ (price of the headphones) + 50$ (for delivery & taxes), but I was extremely satisfied. The bass is amazing, the wireless technology is wonderful, the durability is something anyone will appreciate. The design, well that depends on the taste of the person & I liked it. Now people complain that it is not as what promised by the SMSAudio company that it is able of transmitting for about 50 feet range but all the companies LIE about the specifications (The range can go up to 30 feet) !! overall it is the BEST Wirelss headphones

These headphones are unbelievable. The best pair I have ever had. The sound is incredible. I was on a plane and went to the bathroom and there was no difference in the quality even though I was 30 feet from the IPAD SOURCE.

KLEER wireless FTW

January 17, 2012

I had a chance to listen to these at the CES show and i was impressed with the sound.

First off, these headphones use KLEER technology for their wireless. I'm a big fan of this and have been since Sennheiser used it in their RS 180. IMO it is the best for wireless because it doesn't really have any interference or noise or static. Plus, it has really good range. I put the headphones on and can walk around the house, go to the bathroom, make some food in the kitchen... all while listening to the TV and without taking the headphone off.

Back to the Syncs. I like the design of the cans and the simple to use controls on the sides. i found them very easy to use. Plus, the buttons stick out enough (and are big enough) that you know what button you are pushing without having to take the headphones off.
