Avantree BTHS-NB03-BLK - Personal Speaker & Headphone 2-in-1

• PERSONAL SPEAKER & HEADPHONES 2-IN-1: Turn up the volume on the personal surround sound speakers or enjoy your music in private without disturbing others on the in-ear headphones (earbuds). You can easily switch between the two modes using a handy toggle switch.
• PORTABLE-WEARABLE SPEAKER: Free up your hands and ears. With this wearable speaker on your neck, you can enjoy music whether you’re doing housework indoors or walking your dog outside.
• SUPERIOR SOUND & EQ MUSIC MODE: Hear robust bass and crisp treble-balanced sound from the high-performance premium drivers which use CVC6.0 noise-cancellation technology. You can even choose from three different music modes: bass boost, normal or treble boost to suit your individual preference.
• USER FRIENDLY DESIGN: Easily make calls, skip music tracks, adjust volume and more, with easily accessible and intuitively placed function buttons/switches. A useful anti-loss function will warn you with an audible out-of-range warning if the distance between your audio device and the NB03 is over 10m (33 ft.).
• MULTIPOINT & LONG BATTERY LIFE: The NB03 is an innovative Bluetooth foldable neckband headset. Its unique external speakers and retractable earbuds allow you to listen to your music your way - either as an open-air personal speaker or as a private headphone.
