""While features like Bluetooth® and NFC connectivity make these over-ear headphones impressively practical, their star attraction is their sound. Their mesmerising clarity, strong dynamism and freedom from distortion remove all barriers between you and total immersion in your music. Thanks to wireless Bluetooth® technology, the BTD10s make messy, awkward cords a thing of the past. The NFC function allows one-touch smartphone connection, while aptX® compatibility means you can enjoy high-quality sounds for up to 30 hours on a single charge. If you do manage to run out of battery, though, just take the included cord out of your bag or pocket and plug the headphones in. Nextgeneration music starts here. The BTD10s’ 40-mm drivers produce a truly dynamic bass sound, while the aptX® codec ensures you can enjoy your music with minimal sound quality degradation even when you’re listening wirelessly. The ear pad housing has raised buttons that can easily be recognised by touch alone, so you don’t need to take the BTD10s off every time you want to select a function. There’s also a built-in mic in the inner bottom part of the left ear cup so that you can use the BTD10s as a comfortable smartphone headset simply by using the Answer/End call button. ""
