Inside the box you will get a strap, a long USB-C cable, owners manual and the speaker. This speaker I have to say is heavy so the built in handle and strap works well with carrying what this speaker has inside to give its boisterous appearance and sound. The speaker weighs about 9 pounds or 4.15 kilograms. The build quality is great on this speaker and is made out of premium materials. The speaker on top has a built in handle with two aluminum hooks to attach the supplied strap to. Underneath the handle you will find 7 buttons (power, Bluetooth pairing, volume down, multifunction button, volume up, light control button and, party mode button. On top of the multifunction button you will find four leds which displays the battery level, ontop of the Bluetooth button is an indicator led and the power button has an indicator led which lights up when the speaker is powered on. On the front of the speaker you will a metal grill with the EarFun logo in the middle which underneath the grill you will find two 4 inch 30 watt woofers and two 20 mm 10 watt silk tweeters as well as two leds which light up when the speaker is powered on and which you can change and adjust in the EarFun app. On the sides you will see a passive radiator on both side and on the back you will find a rubber flap which underneath has two USB C ports (In and out) and an aux port. This speaker is also ip67 rated which means this speaker is dust proof and water proof. I only have one uBoom X speaker so I was not able to test the stereo mode or party mode on this speaker but supposedly you can pair up to 50 of these speakers for party mode and you can’t pair to other EarFun speakers.App:The EarFun app is a must with this speaker. Once you download the app you will be prompted to download the latest firmware for the speaker which at the time of this review is 0.39. In the app you will also be able to adjust the EQ settings yourself or select through a variety of different EarFun preset EQ settings or seven different tunings made my Oluv which he made for this speaker. You also will be able to toggle through different light settings as well as select video mode which lowers the latency on the Bluetooth connection.Sound:This speaker packs a great punch. It has deep lows, great mids and, crisp highs. I also toggled through different EQ settings and found zero distortion regardless of which EQ setting I selected. I also toggled through Oluvs EQ settings and found his EQ settings lowered the volume levels tremendously on this speaker. Oluvs EQ settings are: Studio, Indoor, Indoor+, Outdoor, Outdoor+, Boom XXX and, Ground 0. My favorite EQ settings so far is Outdoor + and, Ground 0. (See videos and listen with headphones to get the best audio experience.)Overall I am impressed with this speaker just wish it would be able to pair with other EarFun speakers.(Sound samples provided in my videos contain music that I don’t own any rights to.

For the record, I own 17 Bluetooth speakers and follow the entire market of new ones coming out.First thing to mention. Oluv knocked the tuning out of the park, even more than the Uboom L. This is by far the most neutrally tuned Boombox speaker I've ever come across in the "Studio" mode which was tuned to sound like a Neumann KH80. There's also Indoor, Indoor+, Outdoor, Outdoor+, BOOM xxX, and Ground 0 (for use outdoors when placed on the ground) modes selectable in the App which boost the bass and treble at the ends to different degrees. Myself and I think most people will prefer the Indoor (a little bass boost) and Indoor+ (more bass boost) modes the most, unless you're looking for a lot more bass where the Outdoor, Outdoor+ and BOOM xxX modes shine. The tuning does a really good job at not having the bass overwhelm the midrange detail which a lot of other speakers don't do very well. There's also a 10 band EQ if none of the presets are exactly to your taste.It also does low level listening extremely well like the Uboom L, just with deeper bass due to the larger drivers. There's a lot of low volume steps in the Indoor and Indoor+ modes to find your perfect low volume level. All the other modes are more for louder outdoor use and have volume steps spaced more evenly across the mid to high volume ranges. It's really well thought out.For those with a Uboom L, that speaker could be a little harsh in the treble as it was designed to be more neutral off axis so there's some treble boost when listening directly on axis. The Uboom X has much better off axis dispersion due to the real dome tweeters and doesn't have any boost in the Studio mode and just a slight boost in the Indoor modes and more in the Outdoor modes. The other issue with the Uboom L was at high volumes it would lose a ton of bass and wasn't that great outdoors. The Uboom X obviously due to its size and power goes a lot deeper and can hold on to more bass at higher volumes.This speaker measures 10db down at around 38hz, so it goes deeper than the Blast and Boombox 3 and the same as the JBL Encore but not quite as deep as a Go+ Play 3.This speaker will party mode with a total of 50 units, or can TWS in stereo with a 2nd unit. There's instructions in the manual for how to do each which requires a different pairing button press.Also something that a lot of people will like, it charges over USB-C so you can use your smaller battery banks to keep it powered or charge it. It's also IP67 rated like most other speakers in the class and has a 30 hour battery life.It's also noticeably lighter than the Stormbox Blast and much more comfortable to carry at 9.2lbs / 4.18kg (versus the 11.6lbs Blast). Another thing to note, the Stormbox Blast has a curve under the carrying handle which makes it want to fall out of your hand while this Uboom X has a flat bottom handle which stays in your hand better and is just overall more comfortable. The Uboom X also comes with a carrying strap and 2 metal loops to attach it to.You're also able to either change the volume of the power on/power off beeps or shut them off completely in the app.As for downsides, there's not many. It won't get quite as loud as a Boombox 3 or other higher powered speakers, and doesn't have quite as deep of bass as a Go+ Play 3, but with the amazing neutral tuning, I personally find this speaker to be my favorite. The lights can be a little cheezy, but it's really easy to turn them off. Also on that note, you can select any color you like for the lights in the app.

I decided to keep this speaker for one main reason: the special EQ settings by Oluv. Oluv did some software magic and developed special EQ settings that take full advantage of the hardware of this speaker that far exceed the default speaker settings. The Oluv EQ comes with the device and is available in the EarFun app.I was looking for a boombox type thing that would allow me to vibe out and be fully engulfed and swallowed by bass. Unfortunately if you want that experience from a portable speaker, the JBL boombox is the only one I’ve found to be able to put out that much power. But this one is definitely a strong contender and is good enough for me. It’s also nearly 1/4 the price which is also what helped me decide to keep it.But seriously, those Oluv EQ settings are magical. They actually transform and elevate the speaker and make it well worth the price and more. It’s hard to believe the difference they make. I definitely would’ve returned this thing had it not been for them being available.
