Retail Box WHAT IS IN THE BOX Bose QuietComfort Wireless Bluetooth Noise-Cancelling Earbuds PRODUCT DESCRIPTION Silence means better sound. That\'s why the Bose QuietComfort Wireless Bluetooth Noise-Cancelling Earbuds block out distracting background sounds and lets you focus on what\'s playing. You can choose just how much you want to block out too. Let in ambient sounds while you\'re walking down a busy street or eliminate all distractions for pure focus while you\'re working. Switch to full transparency mode to have conversations without removing your earbuds. Bose lifelike sound These small buds produce big sound. The EQ is automatically balanced for you, so you\'ll appreciate the lows and highs of your favourite songs at any volume. Paired with the silence of noise-cancelling, you\'ll hear all kinds of details in your music that typically get lost, such every note strummed on an acoustic guitar. Practical design Rated IPX4 for water resistance, these earbuds will see you through casual workouts – and you don\'t have to worry if you get caught in the rain. Touch controls make it easy to control your music and answer calls. Phone calls are loud and clear thanks to mics that separate your voice from background noise. You can setup your shortcuts – along with naming your buds, customising the noise-cancelling, checking your battery, choosing your voice assistant, and more – with the free Bose Music app. Handy charging case The Bose QuietComfort Earbuds provide up to 6 hours of battery life between charges. Simply pop them in the charging case between listens for an additional 12 hours of battery life. When you\'re in a rush, just 15 minutes of charging will give you up to 2 hours of playback time.
