Verdict

The boAt Stone 850 is a portable wireless stereo speaker featuring a 16W RMS audio output driven by 44mm dynamic drivers and dual passive radiators. Its key advantages include an IPX6 water-resistant rating, True Wireless Stereo (TWS) functionality for pairing two units, Bluetooth 5.0 connectivity within a 10-meter range, AUX input support, and an integrated microphone for voice calls. The device is equipped with a 4000mAh battery that delivers up to 13 hours of continuous playback at 60% volume, further enhanced by ASAP fast charging that yields 150 minutes of playtime from a 15-minute charge via a Type-C port. However, it lacks advanced Bluetooth codecs, has no official dust-proof rating, and its total battery life significantly drops to around 5 hours when used continuously at maximum volume.
