  • Semi-in-ear ANC Earphone
    Semi-in-ear ANC Earphone

    DaVinci, a semi-in-ear adaptive ANC noise-canceling headphone solution of Sound+, is a complete machine solution that combines algorithm, software, hardware and structural design.

Product Specification and Advantages
  • Comfortable wearing, quality noise reduction

    This semi-in-ear ANC solution maintains a good ANC effect while ensuring its wearing comfort, and its overall noise reduction depth is better than that of competing products.

  • The acoustic structure and algorithm cooperate with each other

    Relying on its acoustic structure and unique adaptive algorithm, most consumers can obtain good noise reduction effect when wearing it.

  • Cost-effective

    This whole set of solutions can be run on BES low-resource platform, which is extremely cost-effecti
