PineBuds Pro ANC Wireless Earbuds are engineered with open firmware, allowing you to customize your audio experience. Enjoy superior sound quality, immersive noise cancellation, and effortless use all in one device.

FEATURES

• User can flash in PINE64 community open firmware when becomes available. The community firmware may beyond typical TWS earbuds functionality.
• Every earbud craftmanship tuned for optimum performance.
• Small and lightweight earbud design for long period comfortable fit.
• The most advance active noise-canceling wireless earphones, transforms listening with up to 45 dB of active noise cancelation.
• A custom design of smaller NC acoustic module that combines a proprietary transducer, and feedback microphone in a sealed enclosure. This allows module sits closer to eardrum for the most effective noise cancellation with the lowest computation error.
• A custom design 6mm small size transducer packs high output and strong bass performance despite its compact size and can outperform typical 10mm transducers.
• Dual mic voice beam foaming, echo cancellation, and environment noise cancellation (ENC).
• Capable connects to multiple host devices, but not simultaneously.
