Ultimate Ears - WONDERBOOM
Compact Bluetooth Speaker

By Kevin Nakano

Ultimate Ears WONDERBOOMUltimate Ears has just introduced the new WONDERBOOM™, an affordable ($99.99), compact and super-portable Bluetooth speaker that not only sounds great, but also provides up to 10 hours of music for your next party. More amazing is that the WONDERBOOM™ is stated to be completely water-proof, making it ideal for summer events that include water, on which it will float. Controlling music is as easy as pressing the button on the top of the unit (where the UE logo sits). A single press controls play/pause and a double press skips to the next song.

The WONDERBOOM™ sits on a 2-inch wide base with a 3.7-inch overall diameter and stands about 4-inches high. The design is very stable and doesn't tip over easily. The unit weighs less than 1 pound, making it convenient to carry around with the attached leash.

Connecting to a Bluetooth device is easy. Simply hold down the top connection button and it will make a sound and start flashing rapidly while it enters the synch mode. For those looking for more sound capability, two can be used to create a larger sound field. However, they cannot be configured as left and right channels.

Ultimate Ears WONDERBOOMColors
The WONDERBOOM™ is available in six different color schemes (Stone, Phantom, Fireball, Subzero, Cashmere, and Lilac). It's nice to see that there's a great selection of colors available. The WONDERBOOM™ comes with a 2-foot micro USB cable for charging the unit. No other accessories are included, so you have to get your own power adapter (or computer) for charging.

Ultimate Ears WONDERBOOMCharging Port
The rear port on the back of the unit accepts the included micro USB cable for charging the speaker. There are no other electrical interfaces on the WONDERBOOM™. It's important to make sure that the rear cover is securely snapped into place to prevent water from entering the back connector when used in damp or wet environments. This is likely the biggest threat to water getting into the unit.

Audio Performance
One might expect a rather thin sound from such a small speaker enclosure, but if you know anything about Ultimate Ears, they never disappoint when it comes to sound quality. I have several of their products and they have been great, both in audio performance as well as reliability. My guess is that they would not produce a unit if it cannot pass their strict sound quality tests. While there are physical limitations with a smaller audio player, the WONDERBOOM™ has been tuned to sound very good with amazingly good bass response. It cannot play as loudly as larger units, but for most applications, it works very well.

Ultimate Ears WONDERBOOM™ is a reasonably priced Bluetooth speaker that sounds fantastic. The only real useful feature missing from this speaker is the ability to answer phone calls. Even without this feature, the WONDERBOOM™ will meet the needs of music lovers who spend time in harsh environments. The build quality looks good on this unit even though I didn't get a chance to abuse it to verify its rugged appearance.
