vivo近期发布了支持Wi-Fi无损音频传输的旗舰真无线耳机TWS 5 Pro，该产品最高支持4.6Mbps的传输速率[1]，超越小米Buds 5 Pro Wi-Fi版的4.2Mbps[1]。然而，业界对微功耗Wi-Fi在可穿戴设备上的实现路径出现了分化。vivo采取私有方案，通过手机与耳机点对点直连的方式实现Wi-Fi传输[1]；而高通XPAN技术则让耳机直接连接Wi-Fi接入点，支持用户在超出蓝牙覆盖范围的地方继续使用[1]。
高通XPAN支持24bit/192kHz的无损音频标准[1]，在传输24bit/96kHz无损音频时的功耗水平与96kHz有损蓝牙相当[1]。小米Buds 5 Pro Wi-Fi版单耳机续航可达10小时[1]，证明了微功耗Wi-Fi连接的可行性。高通CEO安蒙在1月CES上阐述了这一技术愿景：在蓝牙功耗级别下运行Wi-Fi，使用户即使远离手机也能获取独立IP地址，直接与智能体连接[1]。高通在6月COMPUTEX 2026宣布其技术将覆盖低于2mW级别的耳机平台[1]，预示这一微功耗方案有望在个人AI终端中广泛应用。
Vivo has introduced the TWS 5 Pro, flagship true wireless earbuds featuring Wi-Fi lossless audio transmission with a maximum transfer rate of 4.6 Mbps [1]. This marks a competitive step in the emerging category of Wi-Fi-connected wearables, surpassing Xiaomi's Buds 5 Pro Wi-Fi edition, which supports 4.2 Mbps [1].
The two manufacturers employ notably different technical approaches. Vivo uses a proprietary solution enabling point-to-point direct connection between the phone and earbuds [1]. In contrast, Qualcomm's XPAN ultralow-power Wi-Fi technology allows earbuds to connect to Wi-Fi access points, permitting continued use beyond Bluetooth range [1]. Qualcomm's XPAN supports 24-bit/192kHz lossless audio, with 24-bit/96kHz lossless transmission consuming power equivalent to standard Bluetooth at 96kHz [1]. Xiaomi's Buds 5 Pro Wi-Fi edition achieves up to 10 hours of single-earbud battery life, demonstrating the practical viability of ultralow-power Wi-Fi connectivity [1].
Qualcomm CEO Amon noted at CES in January that Wi-Fi operating at Bluetooth power levels allows users to obtain IP addresses and communicate with intelligent agents without relying on their phones [1]. Qualcomm announced at Computex 2026 in June that its technology extends to earbud platforms consuming below 2mW [1]. This technological advancement could enable wearable devices to connect directly to cloud-based AI services without smartphone intermediation.
