Question: I'm looking for something between 18w-20w. How many watts is this speaker?
Document: Speaker puts out some great sound for being small. I love the idea of how you can get a different sound by utilizing different surfaces (glass, metal, wood, etc). However, if you are expecting something super loud out of this, this is not the speaker for you. This is purely for personal use and not something you can crank up for parties (unless it is a party for two).
It's hard to explain to anyone how this product works but it turns anything it touches or stand upon into a speaker cabinet. Great product. It is heavier than most wireless speakers out there but I think it's well worth it. I'm giving this to everyone for the holidays and to my kids in college. You don't need a stereo system with this little gadget. I find the sounds is best when on large wood tables or cabinets.
I have been looking for a small but powerful speaker to go with my Imac. I hate cords. This small unit not only looks great, it is small and works through bluetooth and you can charge it. So no wires! I put it on my five foot round dining table (that also functions as my desk) and the bass is incredible. Its like having a giant subwoofer around (but not annoying). I would highly recommend this product.
It definitely has the surprise effect that we were looking for in a present for our techy friend.Not 5 stars because, if I had to buy one for me I would hesitate with a wireless loudspeaker.
Quick to ship. Quick to setup. Even my wife likes it! PLUS... great after-the-sale communication. And I do mean GREAT. I had a problem and they fixed it immediately. Result: The sound from the Bass Egg fills my office 15x25' office. I've tried several speakers of this type and settled on this when I'm home and a different product (a little bit lighter) when on the road.
Bought this for my husband and he loves it! No matter what you place it on, it turns it into a speaker.
This little speaker is a wonderful idea, however we are very unhappy that this Bass Egg does not work with our BOSE Unit.
I really like it. It turns anything into a speaker. Would recommend to anyone that likes to listen to music on the go.
Best speaker i have ever had. It is so small and so loud and also looks really cool. And the price is beyond a good deal for what you are getting
I love this bluetooth vibration speaker. I was introduced to it by Whoopi Goldberg of The View. It's very powerful for the size ... I recommend it highly,
Answer: I'm not sure it has a specific wattage. By its self it doesn't really put out much sound. It all depends on what surface it is resting on as to how much sound is produced. It's more of a novelty item. I wouldn't recomend it
