    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.

    nice headset
    there is a slight gap in the product,but overall it's good.The sound quality is great for a bluetooth headset.The materials that touch the skin are almost imperceptible!Moderate battery life can last up to two days.

    Very effective
    The only snag is that the earpiece sticks out making sleep difficult on long haul flights, but this is a minor issue.
