Shokz OpenFit Air 2 Open-Ear Wireless Earbuds in White - T520-ST-WT-US

Shokz T520-ST-WT-US OpenFit Air 2 Open-Ear Wireless Earbuds in White

Go light. Stay locked in. Shokz OpenFit Air 2 T520-ST-WT-US brings lightweight, open-ear listening to workouts, commutes, desk time, and everyday movement. Its adaptive ear-hook form rests securely around the ear while skin-friendly contact materials and an open ear canal help reduce the pressure associated with in-ear wear. Because surrounding sounds remain accessible, the earbuds suit walking, jogging, hiking, camping, gym sessions, and daily routines where awareness matters. The Standard White configuration adds a gradient finish, and the slim charging case slips neatly into a pocket between listening sessions.

Music gets an energetic foundation from Shokz Bassphere, a compact dual-driver architecture designed to produce bigger sound from the open-ear format. OpenBass 2.0 processing adds depth and texture at low frequencies, while DirectPitch Technology aims audio toward the listener and helps limit sound leakage to people nearby. For conversations, two microphones work with AI noise reduction to concentrate on the user's voice in busy settings. Pressure-sensitive controls also make playback, calls, and volume easier to manage by feel, with less chance of unintended input from sweat, water droplets, or hair than the previous touch-control design.

A full charge provides up to 8 hours of listening, and the charging case expands total playtime to as much as 36 hours.¹ Quick charging supplies extra listening when plans change. MultiPoint Pairing maintains connections with two devices for convenient switching, while Google Fast Pair and Microsoft Swift Pair streamline setup on compatible systems.² Bluetooth 6.1 supports a wireless range of up to 33 ft under suitable conditions.³ In the Shokz App, listeners can choose preset or custom EQ modes, remap controls, manage multipoint connections, ring misplaced earbuds, and receive software updates. Sweat, splash, and rain resistance round out an open-ear design made to move through active days without closing listeners off from the world around them.

Key Features

Adaptive Ear-Hook Comfort

A narrow 0.75 mm nickel-titanium alloy frame flexes around the ear to balance gentle contact with movement-ready stability. The speaker sits at a 30 degrees angle, guiding audio toward the ear while preserving the open fit.

Compact Bassphere Sound

Two high-sensitivity 11.8 mm round speakers form the Bassphere system. Shokz describes their combined acoustic performance as comparable to a 16 mm round speaker, bringing substantial output to a space-conscious earbud design.⁴

Confident Pressure-Sensitive Control

A tactile locating point helps the finger find each control area without relying on a touchscreen-style tap. The interface senses pressure but does not physically depress like a traditional mechanical button.⁵

Focused Voice Pickup

Dual microphones and AI processing target the wearer's speech while reducing environmental noise, supporting clearer calls at busy intersections, in active spaces, or during a workout.⁶

Listening Tuned to You

The Shokz App offers four preset EQ choices - Standard, Vocal, Bass, and Private Mode - plus two custom modes. It also provides access to control assignments, MultiPoint Pairing, earbud-location ringing, and feature updates.
