【Immersive Sound Effects】 Utilizing MIATONE's unique audio processing and dual-precision full-frequency acoustic stereo drivers, the sound quality of the BOOMBOX Bluetooth speaker is significantly enhanced. It handles crisp highs and mids brilliantly, with no noticeable crackling at maximum volume. Using DSP technology, dual premium subwoofers and passive aluminum elements on both ends enhance the deep and accurate bass that complements your music. No exaggeration or distortion. 【TWS Function】 You can pair 2 Bluetooth speakers for a total of 32 watts of surround sound. Combined outputs deliver full stereo, true-to-life sound. 【Stable Cylinder-Shaped Shell】 The mesh provides enough grip to let this portable speaker go in your hand without worrying about losing your grip. Rubber tips on both ends prevent slipping when standing and absorb potential damage, cushioning the speaker gently after a big drop. So this speaker is perfect for outdoor sports such as skiing, golfing, cycling, hiking, and camping, etc. 【Bluetooth V4.2 Range Test】 If the wireless speaker is in a corner and blocking walls, it will start to cut in and out about 33 feet away. So you can use this speaker with your phone to play Pandora and place the speaker outside and the phone within 33 feet of it. The range is decent in a straight line of about 100 feet without any obstacles or walls. So you can place the speaker up to 100 feet away from an Echo Dot or Echo or other Bluetooth device.
