The Sony MDREX650 has everything a pair of in-ears should have from sound quality to its comfortable fit. This headphone is all about brass, which is an element that has been used to create musical instruments for hundreds of years. The brass brings a clean and sound-distortion free audio experience. 

Clean and Sound-Distortion Free

The internal sound path and the enclosure of the Sony MDREX650 are made of materials used to create trombone. The major advantage of the solid brass housings is its density, which suppresses unnecessary vibration, which brings clean and distortion-free sound, Richer Sounds reported.

Its oversized inner ducts are also made with brass, which significantly enhances the treble clarity. The Sony MDREX650 also has the powerful 12mm neodymium drivers with sculptured air vents that offers optimum bass performance and accuracy.

The Best Pair of In-Ears in Town

The driver enclosure has a rounded end, which makes it fit the ear in a position that isolates unwanted sound, What Hi-Fi reported. But it is not intrusive. In fact, it is easily one of the most comfortable headphones in town.

Its small diameter plug and angled profile makes the headphone fit securely and comfortably in the ear. It has hard hybrid silicone on its outside, while its inside has softer hybrid silicone for excellent comfort. It comes with four different sizes that the user can choose from to get the best comfortable fit.

It also has an open and expansive soundstage, which provides an impressively immersive performance. It has an inline mic and remote to make it compatible with the user's iOS and Android smartphones. It only weighs 9g, making it perfect for people who are on the go.

For great convenience, the Sony MDREX650 has knot-free cord, which makes it easy to put on without troubling with the tangles. The Sony MDREX650 is priced for only £39.95 or $49.21.
