    Overview

    Sony has been an industry leader in audio for decades and this offering is the culmination of decades of research, design and technology. Passive noise-cancelling works with a comfortable design and soft, silicone earbuds to give you an excellent audio experience. Wireless Bluetooth technology allows for easy wireless streaming from your smartphone so that you never have to hassle with cables or cords.

    Comfortable in-ear design gives you great bass response and a comfortable fit for long-term use. The smaller design of these headphones makes them easy to transport. The 9mm high-sensitivity driver unit will give you excellent quality sound and with Hi-Res Audio support you’ll hear all the finer details in your music.
    Hi-Res Audio

    With Hi-Res Audio technology built-in, you can play ultra-high quality uncompressed audio. Take full advantage of this unit’s capabilities thanks to the Hi-Res audio support.

    Passive Noise-Cancelling

    Passive noise cancelling is achieved purely through the design of these headphones. A cushioned ear piece blocks outside noise so you can spend more time listening to music and less time listening to noise.

    In-Ear Design

    In-ear headphones offer greater portability and a comfortable fit for extended use. Easy to carry, high quality and very portable; in-ear headphones are a great choice if you commute frequently and don’t want to carry larger headphones with you.

    NFC and Bluetooth

    You’ll never worry about connectivity again. NFC and Bluetooth technology make it easy to wirelessly share your music. Using NFC, you can connect your device to this unit with one-touch, for easy audio streaming.

    In ear Sony Noise Reduction Headphones
    I bought these a couple of weeks back and used them on my train journey home from holiday this weekend and loved them! The train noise including the air con was all blocked out and I could hear my music perfectly. Very comfortable they come with a range of ear piece covers which is great. Charging worked fine. I've only used them for a couple of hours so far, but I love them. Pink is so fun too!!

    Stellar headset
    Bought to replace a 3 year old set that are wearing out, these earphones don't disappoint. A robust build, good battery life and a nice pouch in which to store them. The sound is excellent using apt-x; the bass is punchy and controlled; the mods and treble both very good. An added bonus is the included cord with which one can connect directly to a phone or mp3 player, bypassing the units internal battery. I haven't listened to any hi-tech tracks (although my phone supports them); but I can say that these are the best Bluetooth phones I have heard. Sony are great for audio quality, and at this price far better than rival offerings from the likes of Jabra, Bose, Plantronics et alia.
