Tune 510BT — Foldable Bluetooth Headphones with Pure Bass, Microphone, Up to 40 Hours Battery (Black)

If the headset feels too tight, place it over a ball or similar rounded object and leave it untouched for at least 24 hours; repeat if needed. Also try adjusting the length of each earpiece until both sides sit comfortably. Pure Bass sound delivers the deep, powerful low end these headphones are known for. Wireless Bluetooth streaming lets you listen without cables and can switch between two paired devices so you won’t miss incoming calls. Battery life lasts up to 40 hours; recharge fully in about 2 hours using the included Type-C USB cable. A quick 5-minute charge adds roughly 2 hours of playback. Built-in microphone and ear-cup controls make hands-free calls and on-headphone sound management simple. Press the multi-function button to access Siri or Hey Google. The Tune 510BT features an adjustable headband and a foldable design for compact storage and a comfortable fit for most head sizes.
