Our take on the BOOM Swimmer

by Ralph Graves

The waterproof speaker that really can go anywhere

The BOOM Swimmer is not afraid of the water. This durable little Bluetooth speaker can be immersed to a depth of 3 feet for up to 20 minutes, and it plays music wirelessly from your smartphone, tablet, or other Bluetooth-compatible device. Use it anywhere there's a chance of getting soaked — poolside, in the shower, on the slopes (but don't take it scuba diving). Not only is the Swimmer waterproof, but its rugged casing is also shock-resistant and dust-resistant, too. Perfect for a day at the beach.

Use the Swimmer's flexible tail to mount it just about anywhere.

Flexible tail for endless mounting options

The Swimmer's flexible tail means you can mount the speaker just about anywhere. Twist it around a pole, loop it around a shower head, or around handlebars — and lots more.

Lose the tail, add more bass

The tail is detachable, so you can just set the Swimmer upright on a flat surface. The Swimmer also comes with a suction cup. Just screw it into the back and pop in on the wall. And here's a bonus: the wall reinforces the low tones. You'll notice stronger bass when the Swimmer's wall-mounted.

Convenient charging

The built-in battery lasts for up to eight hours of continuous use. Its USB charging cable can either be connected to its AC power adapter, or plugged directly into your computer for easy charging.

Bluetooth A2DP/AVRCP: The Boom Swimmer is a portable Bluetooth speaker which lets you listen to stored music and music apps wirelessly streamed from your Bluetooth-enabled device, such as your iPod touch/iPhone/iPad, Android smartphone/tablet, or computer/laptop. The Boom Swimmer supports Bluetooth A2DP and AVRCP for wireless audio streaming and control. Basic playback controls include Volume up/down, Play/Pause, and Track Forward/Reverse. This speaker pairs with your Bluetooth-enabled device with a single press of a button. Once paired, the Boom Swimmer will automatically re-connect with your device when in wireless range (up to 33').

Note: Due to the differences in Bluetooth technology, some Bluetooth enabled devices may be incompatible, function improperly, or may not support all features when used with the Boom Swimmer.

Water, Dust, & Shock Proof: The Boom Swimmer is IPX7 rated, meaning it can be immersed in 1 meter of water for 30 minutes with its tail on. Feel free to take it with you in the pool, the ocean, or even the shower. It is also dust and shock proof for extra durability.

Full-Range Speaker: The Boom Swimmer waterproof Bluetooth speaker employs a single full-range speaker powered by a built-in amplifier for surprisingly big sound from such a small speaker.

Multiple Mounting Options: On the back of the Swimmer is a flexible tail, that can be looped, twisted or snaked for endless mounting possibilities. You can also unscrew the Swimmer's tail and screw in the included suction-cup, so you can attach the Bluetooth speaker to any flat surface.

Aux Input: The Boom Swimmer is fitted with a 3.5mm auxiliary input for connecting almost any portable audio device with a headphone output. The speaker's flexible tail must be removed to access the aux input.

Rechargeable Lithium-Ion Battery: The Boom Swimmer waterproof Bluetooth speaker is powered by a built-in rechargeable Lithium-ion battery that gives you 8 hours of playback at maximum volume, or 16 hours at half volume. The Swimmer features a micro-USB (type-B) port and comes with a 48" USB charging cable so you can charge the speaker's Lithium-ion battery via a free USB (type-A) port on your computer/laptop or a USB/AC power adapter (sold separately). Completely recharging the battery takes approximately 2 hours. The speaker's flexible tail must be removed to access the micro-USB charging port.

Boom Swimmer

Crutchfield Customer Review (What's this?)
I wouldn't call this "RED" it's more red-orange. The power on/off voice is LOUD! good sound out of a little speaker, long battery life, easy to use, discreet controls. Bright-flashing operation light somewhat annoying in totally dark bedroom situation, good to locate the device, when needed, in the dark. Suction doesn't work on varnished wood for too long.

Good sound

Written By Dave, Boston on Friday, March 14, 2014
Crutchfield Customer Review (What's this?)
This little speaker has a nice solid sound. The rubberized texture gives the impression that it's a high quality piece. This is and will continue to be used in the shower listening mainly to news and sports in the morning. I'm using the "tail" to attach the speaker to the shower curtain rod. I haven't tried the suction cup attachment. The instructions do say that the speaker is waterproof only with the tail, not the suction cup. Also the speaker is heavy for its size and I question the suction cup's ability to keep this thing on the wall. Only gripe I have is the voice that announces "power on" and "power off". Wish there was some way to turn that off.
Good sound, feels like it is fairly high quality, battery life seems good so far.

Written By Brandon, Duluth on Thursday, January 09, 2014
This is a good sounding small speaker. Its super simple design is easy to pair with an Android phone. I love the waterproof feature. My wife and I will use it on our kayaks in Lake Superior. For the money, it's a solid buy.
H2O proof, good sound, easy to attach to whatever...

BOOM swimmer (red)

Written By Bradley, Richmond, VA on Wednesday, January 08, 2014
Crutchfield Customer Review (What's this?)
This Bluetooth speaker sounds good for its small size. The fact that it has a bendable hook, suction cup, and can stand alone is also nice. Perfect for music in the bathroom or shower since its waterproof and is plenty loud to fill a small room with music. You could use it at a pool but don't expect it to be loud enough for something like a party.
waterproof easy to operate (only has a few buttons and was super easy to sinc to an iPad) good sound for the size
None so far, just know what you are getting. A small speaker that sounds good for its size, not something that will be large enough for parties.
