Thanks to IT Home readers Autumn_Dream and 不一样的体验 for the tip!
IT Home reported on November 10 that the NearLink Alliance’s official website lists a speaker with the model number “SL10” as having passed testing. It belongs to Shenzhen Eacome Communications Co., Ltd. (the EACOME brand).
The test suite shows that the EACOME SL10 speaker passed the SLE radio-frequency conformance test, the basic service layer protocol conformance test, and the high-definition audio protocol conformance test. This means the speaker will support NearLink E2.0, also known as NearLink Audio.
According to the official description, NearLink Audio’s physical-layer transmission rate can reach 16 Mbps, with bandwidth exceeding that of traditional technologies. Its ample channel capacity can carry lossless 48 kHz/24-bit Hi-Fi audio. IT Home notes that earphones currently supporting NearLink Audio include the FreeClip 2 Collector’s Edition, FreeClip 2, and FreeBuds Pro 5.

NearLink is a next-generation short-range wireless communication technology led by the International NearLink Alliance. Its wireless communication system protocol stack is divided into the basic application layer, basic service layer, and NearLink access layer. The access layer includes technologies such as Synchronous Low Latency Broadband (SLB) for low-latency services and Synchronous Low Energy (SLE) for low-power, high-reliability services.
The NearLink 1.0 series of standards was released in 2022, and the NearLink 2.0 series was completed and released in 2025. The NearLink Audio standard, designed specifically for audio applications and also known as NearLink E2.0, arrived alongside NearLink 2.0. The industry regards 2025 as the first year of development for NearLink Audio devices.
In addition to the 16 Mbps transmission rate mentioned above, NearLink Audio offers latency as low as 0.25 milliseconds, a 5.5 dB improvement in interference resistance, transmission distances of more than 100 meters, up to 20 direct connections, and Mesh networks comprising hundreds of nodes. It uses a design with a maximum bandwidth of 4 MHz and higher-order 16QAM modulation, and adapts the core Polar code algorithm for wireless audio transmission. This enables it to automatically select the optimal channel when first connecting and quickly switch to a clear channel when interference occurs.
Product testing for the NearLink Alliance is carried out by authorized laboratories. It has currently authorized 3 testing laboratories: the China Academy of Information and Communications Technology’s Telecommunication Terminal Testing and Certification Laboratory, the China Electronics Standardization Institute’s CESI Laboratory, and the Testing Center of the State Radio Monitoring Center. A product’s passing testing and being listed means it meets the alliance’s relevant standards.
Shenzhen Eacome Communications Co., Ltd. was founded in 2010 with registered capital of 4.5 million yuan. It is a national high-tech enterprise and a specialized, innovative enterprise. Its main business covers smart meetings, smart education, AI multimodal interaction, and other fields, and its products and solutions have been used in more than 120 countries and regions worldwide. For this reason, the NearLink speaker is thought to be aimed at office settings and may be an audio device specifically for meetings.
NearLink Alliance members now cover the entire industry chain, from underlying chips to smart devices. The International NearLink Alliance has more than 1,250 member organizations, has released a total of 88 group standards, and has seen cumulative chip shipments exceed 260 million units. Beyond audio, NearLink is also used in digital car keys, smart cockpit interaction, wireless battery management, and other applications.
Phones currently supporting NearLink Audio (NearLink E2.0) include the Mate 80 series, Mate 90 series, Mate X7 series, Pura 80 series, Pura 90 series, and nova 16 series. In addition to the FreeBuds Pro 5 and FreeClip 2, compatible earphones include the FreeBuds 7 and FreeBuds Neo. As the first earphones to support the NearLink Audio standard, the Huawei FreeBuds Pro 5 emphasize master-quality lossless sound and an ultra-stable NearLink connection. Huawei’s online store estimates a final purchase price of 1,099 yuan.
