Open-ear wearable stereo earbuds with Mobius Design, titanium alloy memory skeleton, and medical-grade LSR. Funded $390K+ on Kickstarter, later acquired by ByteDance.
Oladance Wearable Stereo (OWS) Pro defines the premium spec for "full open wearable stereo" earbuds. The flagship features non-in-ear, zero-pressure ergonomic design with a Mobius loop shape. It raised $390K+ on Kickstarter and broke sales records on platforms like Taiwan's zeczec. The success even prompted ByteDance to acquire the brand.
Traditional TWS earbuds cause ear canal pain, increase otitis risk, and create dangerous occlusion during outdoor activities. Oladance OWS Pro uses air-conduction audio and patented Fix Point Noise Screen reverse-wave cancellation to solve sound leakage and bass deficiency in open-ear designs, while maintaining environmental awareness.
External shell uses high-strength PC/ABS composite with self-developed "ceramic skin" coating (8-layer process). Skeleton uses aerospace-grade titanium alloy memory wire. Ear hooks use medical-grade LSR (liquid silicone rubber) with IPX4 rating. PCBA features Bestechnic BES2600YP Bluetooth audio SoC (BT 5.3, dual-core DSP), independent amplifier IC driving 23x10mm dual-layer dynamic driver, Awinic AW86862 pressure-sensing IC, 6x MEMS microphone array. Battery: 150mAh steel-shell cylindrical (x2 earbuds) + 1150mAh Li-Po (charging case).
Estimated ex-work cost at 10,000 unit MOQ, including tooling amortization. Line items are engineering estimates based on reverse-engineering analysis and Greater Bay Area supply chain benchmarking — not manufacturer-confirmed figures.

Three major manufacturing risks: (1) LSR and PC/ABS dual-shot overmolding adhesion failure — solved with atmospheric plasma surface treatment + primer + cold-runner mold design. (2) Open acoustic chamber sealing and driver frequency response consistency — solved with automated 3-axis UV/PUR dispensing + anechoic chamber test stations with laser vibrometers. (3) Pogo Pin sweat corrosion in extreme sports — solved with Rhodium-Ruthenium or Palladium-Cobalt plating + firmware impedance detection.
