Remember Ultimate Ear's\u00a0BOOM Bluetooth speaker? \u00a0Well the company is back with a new and a\u00a0best Bluetooth speaker, except this time it's bigger and better than before. \u00a0\u00a0It's called the UE MEGABOOM and I was given an early production unit to nab the UE MEGABOOM Review. Compare the specs in the UE to our Bose Soundlink 3 review to decide which speaker is best for you. If you want to take this audio up a notch, check out our review of the Phillips StarMaker wireless Bluetooth portable speaker and karaoke system.\r\n\r\nFirst things first: the UE MEGABOOM is dimensionally about twice the size of the first BOOM. \u00a0However, it only weighs 1.7 lbs (lightest in its class), 0.5lbs more than the original BOOM. \u00a0So fair to say it's not as dense feeling as their first Bluetooth speaker. \u00a0Nevertheless, it would seem that it has about twice the amplitude of the original BOOM, which means more firepower without all the weight. \u00a0I dig it. See how the MEGABOOM stacks up against our Yubz Magnum Bluetooth speaker review.\r\n\r\nThe MEGABOOM is also IPX7 rated (vs IPX4 in the BOOM), which means it can survive in up to 3 feet of water for up to 30 minutes. \u00a0And yes, those ports, the charging and headphone jack, are\u00a0sealed right out of the box (with the BOOM you had to attach a rubber covering). And what's more remarkable, is that Ultimate Ears has managed to incorporate a fabric covering over the speakers, which helps improve sound quality (it reduces negative resonance) and all the while repel liquid thanks to a plasma coating.\r\n\r\nPowering the UE MEGABOOM is a massive 3,600 mAh battery (good for up to 1000 cycles and replaceable for just $50, shipping included). \u00a0Included is a 24 watt microUSB quick charger for, well, fast charging. \u00a0To be honest I have yet to get through a single cycle on the battery because it provides up to 20 hours on a single charge (at 50% volume). \u00a0Nevertheless, charging should be painless enough since it will be fairly infrequent, and quick when it does occur.\r\n\r\n\r\n\r\nRead: Best Portable Bluetooth Speaker\r\n\r\nBLE, or Bluetooth Low Energy (by default this will kill the battery in 45 days if left on) is standard issue, which may seem\u00a0moot in terms of a Bluetooth speaker, but actually isn't. \u00a0You see, you can power on the UE MEGABOOM directly from your handset or tablet, provided you've got a compatible device. \u00a0It's convenient if the MEGABOOM is out of reach at the time. \u00a0Of course you'll need to have the UE app downloaded and installed. But if you do you can influence the MEGABOOM's EQ.\r\n\r\nThat all said, Ultimate Ears told me they spent countless hours tweaking and improving\u00a0the Bluetooth radio inside of this speaker. \u00a0And it has paid off, as I can attest to its quality, as I often left my phone in my bedroom, requiring it to transmit through a wall (and me) into my bathroom's shower where the speaker was placed. \u00a0Yes, I used the MEGABOOM in my shower, almost daily, and thanks to the "small spaces" EQ setting it sounded awesome.\r\n\r\nAnd much like the UE BOOM of a time past, the MEGABOOM can be paired with\u00a0another MEGABOOM speaker to form a stereo pair. \u00a0Unfortunately, I don't have a second one in my possession, but in all my experiences with other wireless speakers, this has a massive and positive impact on the quality of sound since the sound stage is vastly increased.\r\n\r\nNow, when it comes to the BOOM vs the MEGABOOM I\u00a0have to be honest and say I'm still a proponent of the original. \u00a0And only because it's more portable and practical to carry, especially if you're traveling long distances or backpacking. \u00a0But as I pointed out earlier, the MEGABOOM only weights 0.5 lbs more than the original. \u00a0However, that all said, the MEGABOOM's amplitude and added features make it almost impossible to pick one of the other. \u00a0IPX7, while moot to some, will make it a much more practical speaker since it can be used on the beach, by the pool, or next to the bathtub, all without the fear of it breaking if it does take a dip. \u00a0 \u00a0So ultimately, who's to say you can't, or shouldn't have one of each?\r\n\r\nThe Ultimate Ears MEGABOOM\u00a0(available in black, blue, red, or purple) is available starting today in the UE store for $299. \u00a0Expect it in Best Buy stores sometime this January.
