The product description emphasizing the heavy bass and ability to annoy the neighbors made me think that I might not be the target market for this product. My musical interests do not run to genres where extremely loud bass is key, like hip Hop or Electronica or club mixes for big parties. I do listen to genres where bass is appreciated (blues and rock) as well as some where over-emphasized bass might be a problem (like jazz and vocal heavy genres often characterized as Americana or Singer Songwriter). I am so glad I gave it a try!The bass is certainly prominent, but rich and warm, unlike the fake bass boosts on some other products. More importantly for my purposes, it has beautiful, clear, well defined mids and highs. It can be very loud with minimal distortion, and still sounds great at both more normal and even low volumes.The other feature that was a pleasant surprise was the Adaptive EQ. I assumed it would just be a gimmick. I don’t know how it works, but it maintains a very consistent sound in radically different environments, from a small contained room, to a greatroom open to a loft, and even outdoors on the deck. Another good feature is the fact that there is no change in sound quality and volume between powered and battery modes.The soundstage is amazing for a single speaker. I can’t imagine why you would need more volume than this speaker produces. In terms of sound quality, I think it easily beats out the Bose Soundplay 30. I would give a slight edge to my Audio Engine HD6’s, but that is to be expected from more expensive, powered, dual speakers. The Hyperboom may even handle bass better, and of course it is portable.Other good points – it has good bluetooth range, and has never dropped or crackled. The battery life is excellent.The app was easy to use, and set up was seamless. I did not try to connect additional speakers, so cannot speak to that function. The EQ function was a nice touch. The ability to pre-load a couple of play lists was interesting, though more would be better, and since you have to have your phone there anyway I am not sure how much it adds. But compared to the abysmal apps shipped with other products, it was a nice change of pace.The negatives – these don’t matter to me but they might to you. It is pretty heavy (maybe just awkward because of size/shape and crappy rubber handle). Plenty portable, but I wouldn’t take it on a hike or public transportation. I am not sure how water resistant it really is. There is a hole on top for the Adaptive EQ (where the ads show drinks being spilled, etc.), and it only arguably splash proof when being battery operated. Attaching power or other components requires removing the rubber cover on the electronic inputs. That cover is also a little fussy to get properly reattached.Overall, this is an excellent speaker and well worth the price.

Best sound quality I could find. I bought the JBL boom box and this one, with the intention of returning the one I didn’t like. Sound quality and volume were most important to me.This was hands down the winner. The JBL is a big bummer. Past half volume it doesn’t increase volume, just messes with the EQ to push the highs harder. A problem I’ve found with most JBL bluetooths that, while their quality isn’t always bad, is misleading and I believe it’s done on purpose. JBL couldn’t handle rock at louder volumes without becoming too muddy and tinny to even distinguish vocals.I like the small foot print on this. Crystal clear and massive sound at max volumes. Battery indicator, simple design, big volume buttons, all nice features. I love the app too. Some hate it, but I like being able to turn it on without going to the unit and having some extensive EQ options. The handle is also nice, although I wish the unit were overall a little more beefed up in the casing. Liking it so much I want to bring it everywhere, but I am more delicate with it than I would be with other portable speakers. IPX rating is enough for rain which is enough for me. I don’t toss speakers into pools and I suspect this could handle a little more than advertised anyway.A dynamic EQ with a mic to gauge the room response is a HUGE plus as well. You don’t have to worry about positioning it right. Put it where you want for good volume and the rest takes care of itself.A lot of people are probably comparing this to others in the price range. The JBL can certainly take more abuse and has a larger battery. Sound quality is always more important to me and if I had to I would sacrifice a lot for it. Luckily with this unit the losses are minor compared to the other speaker. Anything layered isn’t worth listening to on the JBL. I also love that max volume is actually usable on this too. You don’t have to baby it to get a sound you’re willing to tolerate. You’ll get everything you want at great volumes. Heavily layered electronic music to heavy distorted rock/metal comes through without losing anything you remember from all of those songs.

Let me start off by saying that I very much appreciate crips, clear sound, but as I have not yet spent a five digit figure on audio equipment I cant quite call my self an audophile. But good sound is extremely important to me, and I mostly listen to electronic music (house and techno) and reggae – so clear sounds and handling of bass are crucial.This speaker deserves a 5 star rating, no ifs or buts. It is perfectly engineered to deliver clear sound, that will allow you to hear the full range – highs, mids and lows.Will it power your illegal, underground warehouse rave…? Probably not, and it wasnt designed for that – go and rent or buy a proper sound system.But It is the type of sound that is absolutely loud enough to power your back yard BBQ or pool party, wont make your ears bleed and allows you still have a conversation. Take it to the beach, to take over and hear music over surf break and waves crashing, night time bonfires on the beach, etc . I have tested this out and it delivers flawlessly.As far as portability is concerned… This isnt the speaker that you will take when backacking through Europe or Asia for 3 months – or even on a 2 week european vacation, or camping trip where you have to hike for a few hours – it is to heavy for that, and great sound comes at a cost (weight/size). But it is absolutely the speaker to take on your staycation where you drive to your destination, for your beach trip and villa rental, or camping trip where you can drive to the camp site…DO i recommend this speaker..? Absolutely! it is expensive but again, good sound doesnt come cheap. And it sounds superior tp the JBL equivalent. I have not tried to connect mine to another hyperboom, but i am going to buy a second one once they are back in stock.If you are looking for a solid, loud and clear portable music option look no further.

I have a box full of other bluetooth speakers and they are all junk compared to this one. I have two of these now and play them several hours per day. Spend the money and be done with it.

Very impressed with it especially when you have stereo pair them.
