Question: Does the mp3 player fit inside?
Document: Okay,These speakers don't have much bass; no surprise there. I bought these to bring to Mexico to listen to music on the beach and at the pool with my friends. They worked fine for that. My mp3 player has an equalizer, so I turned the bass down. Otherwise it gets fuzzy. Apparently, some other players don't have equalizer options.
I've happily ended the long search for a pocketable speaker system for my mp3 player. The iLuv iSp100 is perfect for this use - compact, fairly inexpensive, self-contained with its own micro plug. Runs on 3 AAA batteries so you don't drain your mp3 player. The speakers come with a  drawstring pouch and are just the right size for pack or pocket.The sound?
I bought this product to use in my massage studio with my mp3 player. At first, I was pleased with the speakers. The volume wasn't particularly loud, but in a small massage room, it was perfect. It seemed a great deal for only $10. Unfortunately, they lasted me less than 2 months or so. Within no time the cable began malfunctioning and I had to fidget with it to keep the connection or the sound would be lost.
Sound didn't show distortion even at the highest volume. I must say the other tested speakers are not as easy to carry as the iLuv though.Tested all of them with a Sansa e280 mp3 player and while the iLuv speakers provided a little bit more bass than the iSymphony, the high frequency was noticeably less clear and crisp, even while leaning the iLuv so the speakers faced directly to me.Now, this would be my wishlist for future models: 1. Option to use AC power or at least USB power.
I don't know if this would have prevented me from buying this speaker, but it's a real drawback and poor design.Overall these speakers fit the bill for the price.
I have had quite a few mp3 togo speakers. This one sounds the best ive had. But the battery life isnt any good. It takes 3 AAA batteries and doesnt last long. Another prob ive had with this speaker is that the on/off button is on the front/top of the unit. If you have it in a bag u can pretty much count on it turning itself on but not off.
I purchased this as part of a Halloween costume since I wanted to have some character related music playing. It fit right into my pocket, projected loud enough to be heard at a party, and I am happy with the purchase!
I selected these because I wanted mini's that would actually fit in my pocket and the reviews said the sound was quite good...well they easily fit in my pocket and I was pleasantly suprised by the sound. I'm happy.
Pros: This speaker is compact and the quality is actually pretty good for the price.Big Con: The large on/off button is on the front and EASILY pushed on when inside your bag, purse, you name it. It even turns on in my drawer if it falls on the wrong size. They should have made the power button a switch to avoid this huge problem.
This speaker seemed promising when I first received it. However, it wasn't long until it the wiring inside split and the sound became spotty, sometimes even completely fading. I ordered the Altec-Lansing Orbit instead, and like it much better. The iLuv is sadly a no go for me. It isn't well made and the wiring is very flimsy.
Answer: Nope. Nothing does but the electronics and batteries (cable winds around the base, and, in my case, breaks the case when you unwind it).
