Ultra 390 Open-Ear Wireless Earbuds – Ear-Hook Fit, 360 Audio Claim and Charging Case

Open-Ear Ear-Hook Design

The curved ear hooks wrap around the ears for added stability during walking, commuting and light exercise. The design does not rely on silicone tips inserted deeply into the ear canal, making it useful for people who find conventional in-ear earbuds uncomfortable, want greater environmental awareness or prefer a lightweight listening style.

360 Audio Claim

The packaging displays “360 Reality Audio.” This is a manufacturer or packaging claim because verified technical documentation for this exact Ultra 390 model was not supplied. Actual spatial-audio performance may depend on the connected phone, audio application, subscription service and media format.

Claimed Battery Performance

The box claims up to 6 hours of earbud playback and up to 20 additional hours from the charging case, suggesting approximately 26 combined hours under the manufacturer’s stated conditions. Actual battery life may vary with listening volume, call use, connection strength, environmental conditions and battery age.

Charging Case with Digital Display

The supplied case stores and recharges the earbuds when they are not in use. The product presentation shows a digital battery-percentage display. Exact case capacity, charging time and connector type are not confirmed by the visible packaging and should be checked from the final retail box or included instructions.
