Summary: connected to iphone with no problem. sound is very good for the money. have hmdx plus and although they have a better base the sp1 s are great in sound quality all around. have had the sp1 a few weeks now and have enjoyed it a lot. would buy sp1s again.
Summary: Great sound and solidly built. Son will be getting it for Christmas but it tested out perfectly. Blue tooth was quick to connect and all sound better than I'd expected. Great price and service too.
Summary: This thing is great! I love it. I've had it for a year or two now. The sound is still great quality. I listen to it near top volume quite a bit and the speaker hasn't blown out. I'll listen to it for an 2 or 3 hours at a time, and only have to charge it maybe once a week.
Summary: I've been using this speaker for the past 7 months. It's perfect. The price was very reasonable, it's compact, the rubber coating makes it easy to grip and carry, it looks good, battery life is good, and it sounds fantastic for its size. Bass and drum sounds are easily heard. Unfortunately, due to the small speaker size you won't feel them thump. Sound quality is clear with no harshness or distortion.
Summary: Having owned a similarly sized competitor (Jambox), i have a means of comparison here. The sound on this one is substandard. The volume buttons need to be held down several seconds for there to be significant change. The charging (through the computer's USB port) is a pain. And when I got a phone call through the thing I was unable to take it (thus losing the call). Suffice to say, I've passed this one along to my son and got my Jambox back.
