We’ve witnessed many firsts for wireless earbuds. From the AirPods series pioneering in-ear detection, one-tap pairing, and spatial audio, to Sony's wireless earbuds adding advanced technologies such as DSEE upscaling and LDAC support for higher quality audio handling. Even bargain earbud makers like Skullcandy led the brigade on Bluetooth tracking by integrating Tile technology into their buds, which is even on the $29 Dime 3.
But what about the charging case? Why is it that only a handful of brands have figured out greater uses for it other than recharging? Bowers & Wilkins engineered the Pi7 charging case to double as a wireless adapter that streams music in aptX when connected to an analog audio output. There are also bargain bin models with LED screens showing the battery levels for each bud and the case itself.
