The Weofly Boulder Bluetooth Speaker is engineered for those who need powerful sound in a rugged, travel-ready package. At its core is a 52mm dynamic driver paired with a metal bass cone, delivering 10W of output (peaking at 12W) that provides a rich, deep bass experience suitable for everything from live music vibes to cinematic movies. Designed to withstand the elements, the Boulder features an IPX5 waterproof rating, making it resistant to water splashes, dust, and mud. Its build is a thoughtful blend of ABS, fabric, and silicone, ensuring it remains tough yet flexible. A portable strap is included, making it an ideal companion for camping trips, poolside parties, or daily commutes. Connectivity is modernized with Bluetooth 5.4, ensuring quick and stable pairing with phones, tablets, and laptops within a 10-meter range. For those who want to leave their phone behind, the speaker supports TF cards up to 32GB for direct music playback. It also features a built-in microphone for clear, hands-free calling. To elevate the atmosphere, the Weofly Boulder incorporates seven colorful RGB lighting effects that sync with your music, which can be toggled off for a more discreet look. For a truly immersive experience, TWS (True Wireless Stereo) pairing allows you to connect two Boulder speakers together for a wider, stereo soundstage. Powering the device is an 1800mAh battery that offers up to 5 hours of playtime at 50% volume, with a full recharge taking approximately 3 hours. With a low audio latency of 46ms and a 90dB signal-to-noise ratio, it provides a crisp, responsive audio experience that is particularly effective for gaming and streaming.
