Product Features: True Wireless Build – No More Tangled Cables Bluetooth V4.2 USB Rechargeable – 500 mAh Protective Wireless Charging Case One-Touch Bluetooth Calling Magnetic Build & In-Ear Design 1 Full Charge = Up to 3 Hours Playback Conveniently Magnetized: The SoundMates earbuds deliver big sound in a tiny package, so we’ve given the buds magnetic power to enforce that the pair remains stuck together, unlike other Bluetooth buds that can easily get separated and lost. The magnets are completely safe to be around any device, and the earbuds recharge as soon as they are placed back inside their protective charging case. This delivers up to 3 hours of playback from a single charge. Understated Practical Design: The compact-yet-powerful SoundMates design provides incredible sound and volume, but remains understated in design. They are subtle enough to go with any outfit and occasion from the office to the gym, and won’t overpower the simplicity and elegance of your smart device’s design. Single Touch Control: tzumi SoundMates are ergonomic with an in-ear design and built for easy handling during a workout: users can control their calls and play/pause with the touch of a single button.
