True Wireless Earphones with Bluetooth 5.0

These earphones use Bluetooth 5.0 for a stable wireless link up to 10 meters. Each earpiece holds a 50mAh battery while the charging compartment stores 300mAh. A full charge takes about 60 minutes and delivers roughly 4 hours of playback. The drivers cover a 20-20000Hz frequency range at 16 ohms impedance.

Compact Case and Simple Power Needs

The small charging compartment slips into a pocket and recharges the earphones without cables. Power comes from any standard DC 5V source so no special adapter is required. The ergonomic shape stays comfortable during extended sessions and the light build makes them easy to carry everywhere.

For Listeners Wanting Basic Wireless Freedom

Buyers who need all-day battery life without recharging the case will find the 4-hour span limiting. The single Bluetooth 5.0 connection suits phones and tablets but offers no multipoint pairing for simultaneous devices. Audiophiles seeking advanced codecs or active noise cancellation should look at models that specify those features.

Questions about this item

How many hours of playback can I expect from the 50 mAh earbud batteries before they need recharging?

The earbuds provide about 4 hours of use on a full charge, and the 300 mAh charging case can replenish them multiple times before the case itself needs power.

Do the earbuds or the case become noticeably warm during a full day of listening?

With only 50 mAh per earbud and a 5 V charging input, power draw stays low, so heat buildup is minimal even during extended sessions.

What source device and Bluetooth version do I need to pair these earbuds?

Any phone, tablet or computer with Bluetooth 5.0 or earlier will connect within the 10 metre range.
