When you open the box, there will be a piece of styrofoam covering the top. You take that out and you see the speaker sitting in another styrofoam piece. It is inside a plastic wrapping. Along with the speaker, there is a micro-USB cable and a 3.5mm audio cord. There is also an instruction manual and a “Join Our Power User Program” card.

First Impressions: The speaker has some weight to it. It has a nice, rubber material that feels both durable and sturdy. It can easily survive the general bumps and accidental drops. The speaker has a pause/play button, speakerphone button, a volume up button, and a volume down button. The power button is on the bottom. It doesn't get pushed down when the speaker is placed down because it has a raised bottom preventing the button from being pushed when placed on a surface. The speaker also has a nice clip that is permanently attached to it. When I powered on the speaker, it says, "Powering on Bluetooth." I went on my phone and easily paired and connected to it. It showed up as MM526. Once I paired to it, the speaker says, "Paired." I started playing a song as maximum volume (the speaker will say "maximum volume" when you turn the volume up via the buttons). At the bottom of these buttons, you find a battery light indicator (for when the speaker is charging), the microphone, and a light for when the speaker is on and is on Bluetooth mode. The speaker sounds really nice and loud with nice bass. When loud enough, you can look inside the speaker through the grill and see the speaker bounce up and down with incredible sound. Also, you can feel air coming out of the speaker if you put your hand over it. So far, the speaker seems pretty great!

After using it for a while, I can say that the speaker’s battery seems like it lasts forever. It took me a while to finally kill the battery. I noticed that when you disconnect the speaker, it will say ready to pair. Also, if you plug in the auxiliary cable, it will say, “line in.” The Bluetooth light turns red when it is on auxiliary cable mode. When back on Bluetooth, the light will blink when it is trying to pair/connect and will be solid blue when connected. When turning off the speaker, it will say, “Powering off.” I wish you could turn off these verbal statements because they can get a little annoying sometimes. When testing out the speaker phone functionality, I could hear the person perfectly and the other person could hear me okay. I wouldn’t say that it sounds the best when you’re on the receiving end, but it works fairly well. The speaker can produce nice sound all around and I haven’t found any problems with it whatsoever. You can use the clip on the speaker to prop it up at an angle, which proved to be useful when I wanted to direct the audio from the speaker into a certain direction. The speaker would sound find for around 12-15 feet. Going farther away than that, the sound would start breaking up. I feel like the flap that is on the auxiliary cable port and micro-USB port could someday break off, but using it normally and carefully should keep it on there.

When I say the speaker was loud, it was LOUD. It measured 84 dB on my measuring tool. Also, the quality was pretty good in my opinion.

This is great for anyone who loves music and loves to share it with people! This can be great for parties, for having background music, or to simply show off with awesome tech gadgets!

Overall, this is a great speaker and I highly recommend it! With its IP64 grade protection, great build, and great sound quality, you simply can’t go wrong!!

First Impressions:
On the front of the speaker, there are four buttons that control answering/ hanging up calls, pausing/playing media, raising the volume, and lowering the volume. Under those buttons, you will find a battery indicator light that flashes green when charging, stays green when fully charged, and flashes red when the battery needs to be charged. Beside that, there is a microphone, and a Bluetooth indicator light that turns red when 3.5mm cable is in, solid blue when the speaker is paired with a device, and flashing blue when the speaker is not paired. There is also a clamp attached to the speaker so you can attach it to whatever you wish to. The speaker feels very sturdy and is made very well. There is no rattling when the speaker is shaken. When you turn on the speaker, the speaker says, "Power On. Bluetooth" letting you know that Bluetooth is on and "Powering Off" when you turn off the speaker. When you turn the speaker up to maximum volume, the speaker says, "Maximum volume." When you plug in the 3.5mm cable in to the speaker, the speaker also says, "Line In." The power button is located at the bottom of the speaker.

Review:
This speaker is unbelievable. For such a little speaker, it packs a punch. This speaker can get very loud. The sound quality is very good also. The battery life on this battery is amazing. After three days use, the battery still didn't need to be charged. I had to finally leave it on all night to kill the battery. The speaker takes about 3 hours to fully charge. Lumsing claims that this battery is waterproof. I tested this claim and I am happy to report that it's true. I put the battery in my tub and poured about two cups of water onto the speaker while it was playing some music and it didn't even affect the speaker. I also performed a drop test from about 5 feet while playing music and the speaker wasn't phased again. The sound didn't muffle when it fell or anything. This speaker can take anything you throw at it. All four buttons work like advertised. The microphone works very well also. I was able to talk on my phone using my speaker and the other party was able to hear me very clearly. I used both the 3.5 mm cable and Bluetooth to stream music and the sound is great both ways. The Bluetooth transmission range of this speaker is very good also. I had my phone in my room and put the speaker in my basement which is two floors down. I was able to position my speaker and get clear music streaming. I wish there was a seek button so I don't have to use my phone to skip tracks but it's not a big deal. If your in the market for a good portable speaker, this is a great choice.

Pros:
Easy to use buttons.
LOUD!!
Durable
Carabiner clip is super convenient

Cons:
Voice notifications informing you when you're at max volume, powering on/off, enabling bluetooth, etc, are all a bi annoying.
