The JBL Tune 205BT are wireless in-ear headphones featuring a neckband design that lets you wear them comfortably around your neck when not in use. These earbuds utilize 12.5 mm dynamic drivers to deliver sound across a frequency range of 20 Hz to 20,000 Hz, supported by a sensitivity of 100 dB SPL/mW and an impedance of 32 Ohm. Connecting via Bluetooth 4.1, they maintain a stable wireless link up to 10 meters away. The internal 120 mAh lithium-ion battery provides 6 hours of playback on a single charge, and you can fully replenish the power in 2 hours using the micro-USB port. Weighing only 16 g and constructed from ABS plastic, the black frame is light enough for all-day wear. An in-line microphone and integrated playback controls allow you to manage your music and calls without reaching for your phone. These headphones also support voice assistants and include noise reduction and vibration features, making them a practical choice for people who need hands-free connectivity during their daily commute or workouts.
