Open-Ear Design for Situational Awareness

These earbuds leave the ear canal unblocked so you hear music and surroundings at the same time. The flexible joint hooks around the ear for a secure fit that weighs only .01 lb each. They suit commuters, office workers and outdoor exercisers who must stay alert to traffic, announcements or colleagues.

Upgrade from In-Ear or Over-Ear Models

Switching is worth it if sealed tips cause fatigue, pressure or the occlusion effect when walking. The open design avoids ear-wax buildup and lets you hold conversations without removing a bud. Buyers who need active noise cancellation or maximum bass isolation will not get those benefits here.

Simple Bluetooth Pairing and Button Controls

The case charges via the included 12 inch USB-C cable and holds 19.5 hours of extra play time. A single press toggles between stereo and immersive modes, while the built-in microphone handles calls. The IPX4 rating resists splashes, but the open acoustic mesh can admit fine dust or heavy rain.
