The market for Bluetooth speakers has exploded in the past few years, and with good reason: quality has increased and prices have dropped. Every model can stream music from nearly any smartphone or tablet, many of them double as speakerphones, too.
We at CNET have been reviewing them at a steady clip, and we've rounded up more than two dozen of our favorite models, focusing on small and lightweight units that are best suited to travel. Some of the "older" models have been discontinued but are perfectly fine and continue to be offered for sale at great prices, so we're keeping them in the round up until they completely disappear from the market.
The UE Boom 2 originally listed for $200 (£179, AU$180), but has now come down in price. It delivers big sound and is a great choice for outdoor use. This updated version looks very similar to the original, but has improved sound and is fully waterproof. It costs around $130 online.
The Charge 3 is newer but this 2015model is arguably the better deal -- and we think it sounds a little better. You can now find it discounted online for less than $100 (the Charge 3 costs slightly more but is fully waterproof).
With excellent build quality and impressive sound quality for its size, the Bose SoundLink Mini II is near the top of the mini Bluetooth speaker pack, and well worth its price ($200 USD, £170, AU$250). This second-generation version features a built-in speakerphone, longer battery life and USB charging.
A lot of these small Bluetooth speakers sound fairly similar, but the JBL Pulse 2 manages to distinguish itself with a built-in light show that's fairly mesmerizing. It lists for $200, £170 or AU$300, but can be had for less online.
Credit B&O Play for creating a Bluetooth speaker that doesn't look like anything out there already. The new dome-shaped Beoplay A1 is not only the smallest wireless speaker from the Danish company, but also the most affordable at $249, £199 in the UK and AU$379 in Australia. It sounds impressive for its small size and has a high-quality speakerphone.
We were fans of UE's original Roll Bluetooth speaker, a compact, waterproof wireless speaker with a unique design that sounded very good for its size and has decent battery life. The UE Roll 2, which retails for $100 USD (£80, AU$95), but sometimes goes on sale, offers improved range and plays louder. It's one of our favorite mini Bluetooth speakers.
Polk's Boom Bit -- also referred to as the Bity -- is a tiny speaker you can clip to your shirt. As you might expect, it doesn't sound great, but it works well as a wearable speakerphone in the car and can be used for running and on bike rides.
Klipsch's Groove mini Bluetooth speaker is well designed and packs a punch. It's expensive at its list price of $150, but you can find it for a bit less online. It's also being sold in a bundle with a pair of JBL wireless R6 in-ear headphones, which isn't a bad deal.
The Beats Pill+, which charges via Apple's Lightning cable, has a lot to like about it if you can overlook its inflated list price: $229, £189, and AU$267. But it is being discounted online to around $170 (£170), which helps.
Logitech's X300, which can be stood up vertically or sat down horizontally (as pictured), is a solid deal at $70 (£60, AU$80), sounding as good or better than many competing speakers in the $100 price range. Since it's being phased out, you can now find it for closer to $50 online.
Divoom's Voombox Travel 3 is a rugged doughnut-size speaker that plays very loud for its size and retails for as low as $20. (the original Travel sells for as low as £20 in the UK, not available in Australia). While it distorts at times, it's still one of the stronger speakers in its size class.
JBL Clip 2, the successor to the popular Clip and Clip+, is a waterproof micro Bluetooth speaker with a handy tuck-away cord you can plug into your audio source if need be. It costs a little more than $50 online. The Clip 2 is available in the UK for £35 and AU$60 in Australia.
Although it's technically been discontinued, you can still find Logitech's X100 for sale at a bargain price. It's one of the better micro wireless speakers out there, and while its sound is decent for its class, ultimately you'd probably want to pick it over its competitors because you like its design (I do), particularly now that it only costs around $20 online (or £20).
We reviewed Divoom's original Voombox Outdoor and thought it was pretty good for $100. Now the Voombox Outdoor 2 sells for $60 (£40) online and plays very loud for its small size, though it can distort at higher volumes.
Polk Audio's Boom Swimmer is a small waterproof wireless speaker that has a bendable tail that allows you to hook the speaker onto anything you want. When it was first released it listed for $60 (£50, AU$79), but can now be had for less than half that online. The newer Swimmer Duo costs more.
It also comes with a suction cup, so you can attach it to the wall -- or glass -- in your shower. It offers better sound than its small size would indicate, but it gets on the list for its flexible, bathroom friendly design. Available in multiple color options.
