Question: Is it big enought for playing music in park for group 30 ppl? Thanks
Document: Probably the best electronic purchase I've made for less than $150. The sound is truly amazing. I'll agree with other reviewers that sound quality is lost when running on batteries but even with that said, the sound is amazing! We listen to a variety of music and this system handles all genres beautifully !For what we wanted to take poolside in the summer it more than fits the bill! Thanks to Logitech for putting such big sound in a little package for a reasonable price.
This little speaker is a lifesaver. It has great sound quality (much better when it's plugged into a wall but still not bad on battery), and this is even according to my boyfriend who is a sound, well, geek :) It's great to have to bring to the pool, switch to the kitchen while I'm cleaning or the bathroom while I'm getting ready...even worked great for house-party music at halloween w/about 30-40 ppl dancing. Highly recommend.
This is an amazing unit and a great value! It works great with my iPod Touch (4th gen) and iPod Nano (5th gen)Big plusses:1)  Excellent sound, still good sound on battery power. Unlike many portable units, this guy can do decent bass sound.2)  Meets or exceeds my expectations for portability.3)  In addition to playing your own digital music files, is great for use with Pandora internet radio (and presumably Last.FM or others).
It definitely works and the battery is Ok, but it doesn't control the speaker. With the first one at least i managed to make it work once.Thanks Logitech, you could have really built a Bose-killer, but as it is now, it is just another not worth mentioning mediocre "portable" speaker. If you want "big" sound on the way, the Logitech just won't deliver!
I use when I am working in my 3 car garage or in my large bulding 30 ft by 60 ft. The sound is great and it is loud enougth. I want good sound and I want it loud enought to hear it this gives me both.
This is nice, yes, but not worth over $100. I had to end up spending $30 for a connector since it is not compatible with Apple's new ipod and iphone. Also,I was so disappointed when I found a much better, bigger dock at Big Lots for $50 that can even dock ipads. It also came with an adaptor to plug in to my iphone 5 so i can play my ipod.
Again - not really a big deal but would have been nice for a separate stand.-Does not charge you phone while playing-No clock but this is not a big deal as the clock is on the phone.Overall great buy and amazing sound for the price. I would definitely recommend this dock to anyone.
I received this and tried it out right away. It is fantastic. The sound is rich and full. It is smaller than I thought, but it sounds big. I didn't realize it is rechargeable until I unplugged it to move it, but it kept playing. Not as loud, but still good. It sits very sold on the table or counter. The remote is very small and handy, if I don't loose it.
Really like these speakers, I take them to the skate park with me so I can listen to music while I shred. The design is streamline, as small as possible for the output - but large for a portable speaker. There is room for improvement in the sound quality, but I think it is a good trade off considering the price.
This little unit just blows me away. Sounds great! I had large group of people at home for Christmas they could not believe the sound from this small box, even in a large room. I have a large home theater system in the room also, but I don't use it for music as much now that we have this little box that sounds so good for listening to music. I took my Ipod with me to try these units out in the stores.
Answer: Not sure how far apart the ppl are. I'd turn you device on as loud as it can go, & then turn up the LGT to its maximum setting and you'll be able to hear it very well.
