And while it’s not 1oz like the insanely small BIT, it’s still super portable at just 6.7oz. The Swimmer line of travel speakers is IPX7 waterproof rated (that’s really good).
If you want portability but need a more robust waterproof design, upgrade to the Swimmer, or Swimmer Jr (it’s a little smaller).
I reviewed the original Polk Swimmer bluetooth speaker a while back, and this mini speaker has aged beautifully. Polk Boom Swimmer Bluetooth Speaker ($24) Just plug it into your computer or USB charger, and you’re good to go. And the simple direct USB charging means you don’t have to bring another cord or charging port. The tactile volume buttons for changing the volume are great, so I don’t have to dig my phone out of my pocket when I’m biking. But for the price, the portability, and the features, you can’t get mad at this beaut of a travel bluetooth speaker. The only downsides are the short battery life (3 hours) and it’s sweatproof, but not technically The Bit has a built-in microphone so you can connect and use it as a speakerphone or voice command (awesome) while you drive or just to take a conference call or a skype call with your editor while you’re in a noisy place. This thing is so lightweight you can clip it to your bag, or even your shirt, and jam out on a run, a bike ride, skating around town, or anywhere else. At just over 1 OUNCE (yeah you read that right) this ultra lightweight bluetooth speaker isn’t just built for travel-it’s perfect for it. Polk Bit Mini Bluetooth Speaker is bonkers. These super light travel speakers also happen to be the best budget speakers on the list, so it doesn’t hurt that they’re portable and affordable. If the battery lasts longer than one meatloaf song, that’s a bonus, and is needs to have features like an onboard mic, waterproofing, and oh yeah-good sound. That means lightweight (preferably under 1 pound), compact, and easy to carry. The whole point of a travel speaker is that it’s easy to pack and worth taking on the trip in the first place.
