This Bluetooth speaker has the most bass I've ever heard from a wireless speaker

Some wireless speakers like Sonos' speakers use WiFi to play music, which let you play music in any room with WiFi. But Podo Labs decided to go with Bluetooth, and I think it's the right move. 

Most WiFi speakers require their own apps to play music, which is fine, but I'd personally prefer to play music from the source app, like Spotify or Apple Music. And if Podo Labs used WiFi, it wouldn't be able to connect to other wireless speakers from other brands. Plus, unless they come with Bluetooth, WiFi speakers only work where there's WiFi available, which could be limiting if you want to use the speakers outside. By using Bluetooth, the Belle works like any other Bluetooth speaker and you can take it out of WiFi range. 

You can wirelessly connect up to six Bluetooth speakers of any brand to extend and deliver your music evenly or more loudly across a space. I've seen other Bluetooth speakers with this daisy-chaining feature, but not ones that can connect to any brand of speaker. I think that's a great feature, as you don't need to ditch Bluetooth speakers you already own.

Then, there's the subwoofer feature. You can switch the Belle to subwoofer mode while it's connected to your other Bluetooth speakers, and it'll do just what the feature's name implies: act like a subwoofer while your other connected Bluetooth speakers deal with the highs and mids. 

Inside the Belle are two bass drivers, a five-inch woofer, and two two-inch full range drivers. I tested out the Belle outdoors, a tougher environment to sample speakers than indoors, and I was floored. 

I sampled the 100-watt model Belle, which has great-but-not-stellar overall sound quality that would please most people, and it's loud, too. But its main goal is to deliver bass to the bass-heads out there — and boy, does it deliver. I've never heard so much bass and volume come out of a Bluetooth speaker before. At one point, I felt self-conscious that we were bothering the surrounding buildings across the street in the already-noisy New York City. There were a few people working where we were testing the Belle on the outdoor terrace in BI's office building, and we certainly got looks of intrigue. 

I only saw a prototype when I met with Podo Labs' founder Eddie Lee, and it immediately made me think of the $3,000 Devialet Phantom speaker. But unlike the Devialet, the Belle's full retail price will start at $350 for the "Lite" 80-watt model without a handle, and $400 for the 100-watt model with a handle.
