We've analyzed all of the teeniest Bluetooth speaker options out there — those that are small enough to be clipped or strapped onto clothing, or slide into a pocket. These are not yet tested by consumer organizations but we have examined what every major audiophile site, blogger, review site, and tech publication has to say about them.

For now, the best wearable Bluetooth speaker is the Polk Boom Bit. We'll discuss a few somewhat cheaper options below as well, but they have had quality complaints.

Polk Boom Bit

The only current recommendable option among the class of small, "wearable" Bluetooth speakers is the Polk Boom Bit. This "headphone replacement" comes from the celebrated American speaker company Polk Audio. It's designed to clip anywhere, but particularly to the shirt collars of joggers or bikers who don't want to put themselves in danger in traffic. Don't expect it to sound as nice as the in-ear headphones we recommend, but if for safety or other reasons you don't want something in your ears, this is the best portable, personal alternative out there for music, podcasts, and phone calls.

Our Top Pick for Tiny, Wearable Bluetooth Speaker: Polk Boom Bit

Polk Audio is best known for its powerful, refined home systems; we were thus curious to see how its designers have taken on a very small, portable product. The offering, Polk Boom Bit, is by far the lightest quality Bluetooth speaker out there, weighing only 1.2 ounces. It's been reviewed in a number of tech publications by writers and audiophiles who generally were just as surprised and pleased to see Polk try this route.

Most lauded the Boom Bit's design and durability but not been overly impressed by its sound, commenting that it doesn't have "any real bass" and "wisely focuses on high frequency clarity, which makes it bright and easy to hear outdoors". Still, it can go loud enough to be used even in traffic, wearing a motorcycle helmet.

While the consensus is that it's only pleasantly serviceable in terms of sound quality, the lightness and originality of the design got far more praise. It's meant to be clipped to a shirt collar or backpack strap and serve as a headphone replacement for those who don't like things in or over their ears or, or who want to remain aware of their surroundings. It has volume buttons (which also serve to skip tracks), making it easy to adjust as your environment becomes quieter or noisier. You can also use it to take calls when you're on the go.

The speaker was originally marketed as dust- and waterproof (IPX7), but these claims have been removed by Polk, likely, many speculate, due to water being able to penetrate the cap if the unit is dunked. There are no reported problems due to sweat from normal workouts.

Polk says that the speaker can run for three hours at 50 percent volume. Some Amazon reviewers are disappointed by this and also report much less usable time at louder volumes. You'll likely want to plug it into a USB-A charger (on your computer, a wall outlet, etc.) between every outing.

Polk Audio is a reputable, established manufacturer and offers a one-year warranty on this speaker.

Less Recomended Wearable Bluetooth Speakers

A Teensy Cube: Wonfast Smallest Bluetooth Speaker

At a bit more than a one inch cube and weighing just 0.3 oz, the Wonfast Smallest is indeed the smallest speaker out there. It has lackluster reviews and a number of quality complaints, particularly about it breaking down after a couple of months. It does go louder than one would expect for its size, though of course there's little bass end.

A Cheap Speaker with a Hook: Catwood's Smallest Portable Bluetooth Speaker

Catwood's Smallest is incredibly tiny, has a convenient carabiner hook, water resistance, and has largely positive Amazon reviews. Unfortunately, that's the only place where it's been reviewed, and an analysis shows that this speaker's reviews are likely fake.

A Cheap Wristwatch Speaker: The Quokka Premium Bluetooth Speaker

The Quokka Bluetooth Speaker stands out by offering a wristband as well as a hook. At last check it has almost entirely positive Amazon reviews which are quite likely fake, and no serious publications have deigned to try it out.

Lehris Magnetic Wearable Speaker

That didn't last long. This silly-looking, magnetic wearable speaker is not currently available.

Wrap-Up

While its battery life could be better, and it's not going to sound as lovely as full-sized Bluetooth speakers, the lightest and most wearable speaker option is the Polk Boom Bit. We expect more such speakers to be released in the future and we'll update this article when they are. For reference, if you want a similarly cheap but slightly heavier (not wearable) speaker, the one we recommend is the OontZ Curve.
