**********************  Disclaimer ***********************

• For more PineBuds Pro info, please visit wiki page at https://wiki.pine64.org/wiki/PineBuds_Pro
• Dismantling the earbuds can negatively affect performance, especially ANC functionality.
• User needs to use the programming tools provided at wiki page. Any device brick caused by hacking or improper programming may void warranty.
• Excessive flashing Pinebuds can potentially brick the 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.
