Ultimate Ears is a well-known American sound equipment company. They make world-class in-ear monitors, headphones, earphones and speakers. In this segment, we are going to talk about one of their most popular waterproof Bluetooth speakers, the BOOM 2.

The BOOM 2 is a rugged waterproof outdoor speaker. It is shaped like a water bottle, and is easy to clutch and carry. It has a water-resistant and acoustically-invisible skin around its curved body. It has Bluetooth, NFC, AUX and a 15-hour battery. In other words, it is the perfect compact portable speaker to take on picnics and adventure trips.

Let us go over the technology, design and sound of the BOOM 2 in a little more detail.

UE Boom 2 – A Premium Waterproof Speaker For Outdoor Use :

Technology And Design :

The BOOM 2 is designed to stand up to the elements. It is an IPX7-rated waterproof device. It can be immersed in one-meter-deep water for up to 30 minutes without any issues. It is suitable for rafting, kayaking, hiking and camping adventures. You can drop it in the pool and swim with it, tie it to your backpack and hike a mountainous trail, hang it from a branch while you barbeque in your yard. Wherever you are and whatever you are doing, the BOOM 2 never leaves your side.

The speaker has a cylindrical bottle-like enclosure. It has an acoustically-inert fabric covering its curved outer surface. The fabric is water-resistant and does not allow water or snow to seep in. On one end of the speaker there is a power button and a Bluetooth button. You need to tap here to play music. One tap will play the track, two consecutive taps will skip the song and move on to the next track. There is a watertight door on the other end of the speaker. It guards the charging and the audio input ports from water and debris. Along the length of the speaker runs a durable rubber spine with two large easy-press volume buttons.

The device is 180 mm long and has a diameter of 67 mm. It is easy to carry as it weighs just 544 g. On the side where the charging port is, there is a standard camera mount with a detachable D-ring. You can use the ring to attach a lanyard and sling the speaker from backpacks, handlebars, hooks, rods and harnesses. It frees up your hands as you don’t have to hold the speaker. It also keeps you from accidentally dropping the speaker or knocking it against hard surfaces.

The BOOM 2 has Bluetooth technology. It supports sound input from all iOS and Android gadgets like smart phones, iPods, tablets and computers. It has a stunning wireless range of 100 feet which opens up the listening field. The speaker can be paired with up to 8 Bluetooth devices and connected to up to 2 devices at a time. So it allows two people to share the playlist and take turns playing music from their devices.

Another fun feature of the BOOM 2 is that it can be paired with up to 150 BOOM 2 or WONDERBOOM speakers through the Ultimate Ears Boom app which is an amazing feat. It puts the BOOM 2 right up there with other premium Bluetooth party speakers. You get to stretch the soundstage to cover more people. 150 speakers going full blast at once is quite an achievement and no easy job too. But Ultimate Ears is known for making the impossible, possible. And so you have the BOOM 2, a wireless speaker that offers a near-endless listening field minus the hassle of wires.

Apart from Bluetooth, the speaker also has NFC one-touch connectivity. So if you have a sound device that is also NFC-enabled (Android Jelly Bean and higher versions), you can pair them up and play songs with minimal fuss.

The gadget has a 3.5mm AUX input jack for plugging into non-Bluetooth and Bluetooth devices. This makes the speaker very versatile and allows you to play songs from a variety of media source gadgets.

The BOOM 2 has hands-free calling facility. It has an integrated microphone that lets you take calls from the speaker without using your phone. The function is supported on phones that have Bluetooth Hands-Free Profile (HFP 1.5).

The speaker is powered by USB. It has a built-in rechargeable battery that runs non-stop for up to 15 hours on a full charge. It gives you the freedom to stay out from sun-up to sun-down and even beyond without worrying about low battery.

Sound Quality :

The BOOM 2 has voluminous sound. It is fitted with a pair of 45mm active drivers and another pair of 45mm x 80mm passive radiators. The drivers take care of high and midrange frequencies while the passive radiators reproduce the lower end of the sound spectrum. Together they pump out immersive 360ᵒ sound for a thrilling party time. It is loud with crystal clear vocals and instrument sound. It has a top sound level of 90 dBA and a frequency response of 90 Hz to 20 kHz. It doesn’t skip a single note and reproduces the original soundtrack as it is.
