The speaker features premium fabric and a beautiful circular design that will make you want to replace your living room centerpiece with it. Plus, its two 75mm woofers and two 20 mm tweeters produce room-filling sound to get the party started. What’s more, you can simultaneously connect two devices, so you don’t have to fight with your mate over the playlist. It also has built-in noise and echo cancellation, so you can take calls without any disturbance. In addition, it works with Siri and Alexa, so you control your music with voice commands. The Onyx Studio 4 speaker can provide up to 8 hours of music playback with a single charge. But keep in mind that this speaker is hefty (2 kg), so it might be better suited to your bookshelf than your backpack. Don’t you want to make your life a party?
