Over-Ear Bluetooth 5.4 Headphones

The kurdene SP9i-Black are over-ear wireless headphones that connect via Bluetooth 5.4 for a stable link up to 33 feet. They weigh 3.2 ounces and use 16.1 mm drivers with 32 ohm impedance to deliver bass, mids and treble. Built-in microphones isolate your voice for clear calls during workouts, meetings or daily commutes.

Build Integration

No jack is present, so audio comes only through the wireless connection; a paired phone, tablet or computer is all that is required. The charging case stores the earbuds and supplies extra power, freeing you from wall outlets during long days. Soft silicone ear hooks keep the fit secure while you move, removing the need for constant readjustment.

Bundled Extras

The case extends total listening time to 60 hours by adding 48 hours to the 12 hours available on a single charge. Three pairs of earplugs in small, medium and large sizes let you match the seal to your ear shape for better isolation. Touch controls on each earbud handle volume, track skipping, calls and voice-assistant activation without reaching for your device.

Questions about this item

How many hours of continuous listening can the SP9i-Black deliver before the battery needs recharging?

The earbuds provide up to 12 hours of continuous playtime on a single charge, with the charging case adding another 48 hours for a total of 60 hours.

Do the SP9i-Black headphones get warm or noisy during all-day use?

They have no active cooling or fan, so they run silently; the lightweight 3.2-ounce build and over-ear silicone hooks keep heat buildup minimal during extended wear.

What device do I need to pair with the SP9i-Black for them to work?

Any smartphone, tablet or computer that supports Bluetooth 5.4 will connect wirelessly within the 33-foot range — no separate transmitter or cable is required.
