Design and Ease of Use

Boom Swimmer Jr. is a fancy-looking speaker that will not fail to catch your eyes and other people’s attentions. It comes in several color options, so there is no issue in finding the one that suits well to your style and taste. There are two main parts of the unit, which is the bell-shaped head and the bendable tail.

You can use the tail to hang it on anything that you can think of such as the shower head, bike handles, on the backpack, or you can use it as a footer to place it on a table top. It makes this Bluetooth speaker highly mobile, also thanks to the lightweight body of only 0.7 pounds.

On the head area, there are two control buttons for the Power and Volume. The Power button also acts as a Bluetooth button. You can press it to establish a wireless connection to your smartphones or Bluetooth-enabled MP3/MP4 players. It is very easy to use as it takes only seconds to start playing your music. The Volume button functions separately than the volume on your smart devices. Therefore, you can adjust both devices to get the maximum sound output as you wish.

The only complaint that we have about this Swimmer Jr. is the instability of the unit when placed vertically on a table. The tail does not have much surface to balance out the big head.

So, make sure you secure it to something to avoid it from falling on the floor. As a replacement, there is a suction-cup holder that you can purchase with this speaker for a more stable placement. Still, if it falls, it is not a big deal as it comes with the second protective element, shockproof feature! The speaker come with fair price that anyone can get.

Battery Power

For such a small speaker (a little bit bigger than your palms and fits nicely in your hand when you grab it), the battery power is quite impressive. It comes with a 430mAh rechargeable battery that takes about two hours to charge.

We noticed that it depended on the volume power. If you are to set it at a maximum setting, the battery power can drain quickly. On a regular usage, it can go as long as seven to eight hours. There is no battery indicator on the unit itself, but you should be able to see the current battery power on your Bluetooth devices.

Bluetooth Performance

For those who are already familiar with Bluetooth speakers, they will not find any issue with establishing the Bluetooth connection. It makes use of the latest V4.1 Bluetooth technology. By pressing the Power button twice, you can then locate the name of the Swimmer Jr. on your smart devices and perform pairing from there.

Once connected, your smartphone will automatically connect to the same device if it is on and active. It is compatible with many gadgets such as Samsung Galaxy S5, Edge, iPhone 6, iPhone 6S, Nexus, other Android smartphones, iPad, iPod, and other Samsung tablets. The purchase also includes a micro-USB cable and a 3.5mm Aux port, so it also supports a wired connection.

Sound Quality

On top of the unit, you will find a metal grille that protects the 2.5W driver and an internal passive radiator. Thanks to these two audio devices, the sound quality of Polk Boom Swimmer Jr. is rather satisfying. They help to produce a loud, balanced sound and boosted bass performance.

When we tested the unit, we cannot help but notice that the Jr. model has a better sound quality in the midrange level compared to the lower end and high volume. There is a little bit of distortion when set at a maximum level. However, it is not too significant to the extent that it can annoy you.

To find the overall sound performance, we should test it with several genres of music. Based on several user feedbacks and the reviews of professional critics like the DigitalTrends.com and PCmag.com, the manufacturer, BOOM, has done an excellent job in producing clear trebles and highly detailed instruments output.

When you play country or pop music, you can hear clearly the strums of the guitars and the vocals of the singers. However, the sounds of the drums are more in the background, and it prevents the chaos in the music output.

Overall, the sound performance of the Boom Swimmer Jr. is excellent for such a small and cheap speaker. At about $35 per unit, you get great values for your money. You can carry it around while walking in the park or biking around the neighborhood and enjoy decent music at the same time.

Waterproof Feature

With an IPX7 rating, you can bring this unit into your shower and take a bath with it! It can survive an underwater submerge up three feet deep for as long as 30 minutes. If you are an outdoor goer who loves to camp by the river or go on a whitewater rafting, you can enjoy those adventurous activities while listening to this waterproof speaker.
