With incredible battery life (40 hours) and a monster maximum volume level (126 dB), The New Soundboks speaker (yes, that is the official name!) is powerful enough to fill a room or outdoor venue with music.

The IP65 waterproof rating means it will be fine when used in the rain, and it has inputs for both microphones and musical instruments (3.5mm and 6.35mm) in case you want to set up a karaoke session or use it for your band practice.

This isn't the speaker to buy if you want to throw it in your bag and travel; it clocks in at a hefty 33 pounds and is more than 30 inches tall and 20 inches wide.

For those who want a larger Bose speaker than models like the SoundLink Mini II and SoundLink Color II, the S1 Pro might be the solution. It offers 110dB of output; that's more than enough to fill an outdoor event with sound, and it can even double as a PA system in case you want to make announcements or speeches over a microphone.

But it's the Bose touches that make the S1 Pro really stand out. For example, there are built-in sensors to make sure the sound is always as good as it can be, regardless of placement or orientation. You will also get access to a three-channel mixer and independent ToneMatch, reverb, and equalizer controls on two channels.

The Marshall Woburn II speaker is has a classic speaker design, yet on the inside, it boasts some of the latest technology available. That includes two one-inch tweets and two 5.25-inch subwoofers, as well as an amp, Bluetooth 5.0 aptX technology, and a frequency response of 30-20,000 hertz. All that comes together to provide 110 watts of power

It's not all rosy, however. The lack of a battery means the Marshall Woburn II is no good for beaches, camping trips, and other off-grid events (unless you also have a generator). There's also no microphone for hands-free phone calls, and it does not have support for Google Assistant, Alexa, or Siri.

The Turtlebox Loud isn't a big speaker—it only measures 11.50 x 6.50 x 8.75 inches. However, it offers a volume level that surpasses almost all other portable Bluetooth speakers on the market.

At 120dB, the speaker will cut through the wind, rain, and other conditions. That, paired with an extremely rugged design and a sound frequency curve specifically designed for outdoor use, makes it a perfect speaker for adventures and outdoor events.

Because the Turtlebox Loud is rugged, it does have a bit of extra weight. At eight pounds, it's not onerous, but it's not something you're going to forget you're carrying either.

The Aiwa Exos-9 has five powered drivers, a 6.5-inch subwoofer, 200 watts of power output, and a five-band equalizer with four presets, all of which combine to produce an impressive 100dB of volume when the speaker is turned up to the max.

Indeed, it is the speaker's components that help it stand out. Aiwa openly admits it spends less on marketing and endorsements than its competitors, thus freeing up resources to improve its products.

And if you're planning to use an Aiwa Exos-9 at parties, you'll love the Bluetooth lock feature. It means you can either let anyone take over the music or enable a feature that will keep it paired with the current device indefinitely.

The audio quality of a Bose speaker is a given; the SoundLink Mini II is no different. However, this speaker also blows away similar-sized units with its volume. Despite only measuring 2.1 x 7.1 x 2.3 inches, the speaker produces 50W of power and 85dB of noise.

Having Siri and Google Assistant capabilities is also a big plus, but the lack of Alexa will undoubtedly leave some people feeling a bit disappointed. Of course, the big downside of the Bose SoundLink Mini II is the lack of water resistance.

Although it can withstand drops and heavy shocks, you won't want to be using it around the pool on vacation. Those who want water resistance should check out the Bose SoundLink Color II instead.

Some Bluetooth speakers are more portable than others. If you want something you can throw in a rucksack but that still offers a powerful sound punch, check out the Anker Soundcore Boost.

The core design principle of the speaker is to improve the bass on your music. To that end, Anker has included its own proprietary BassUp technology. Combined with the dual drivers and twin subwoofers, the speaker possesses an impressive depth of sound given its size.

The IPX5 waterproof rating means it can withstand a spray of water from a hose or tap but cannot be fully submerged.

If you want to party anywhere, you're going to need a powerful outdoor speaker that can cut through the sound of wind and rain with ease. The Treblab HD77 fits the bill; with 25W of sound output in a 360-degree array, you can fire up this speaker anywhere to get people jumping.

Importantly, stereo output is supported—that's an essential feature for better music quality at parties. Just pair two TWS-enabled speakers together to get started.

Similarly, the IPX6 water rating is vital if you want to use the speaker outside; you don't want the party to end because of a bit of rain. The most significant reoccurring criticism from users is the battery-low warning sound. It starts at around 5 percent and won't stop until you are back above that level.
