Question: iphone 4 Does this product work with the iphone 4?  Read one review where someone said it didn't work consistently with their iphone 4.  Appreciate anyone's feedback before I take the plunge and buy.
Document: I kept thinking someone must have something. I than went to Amazon and found the Logitech s715i available for pre-order. Cnet gave it a good review so I ordered one.I got my Logitech s715i last week and am very happy with it considering the price. It was really well designed with rechargeable batteries, compact design, simple controls that work with my old ipod and iphone 4. I still expected it to be disappointing outdoors but found it to be enjoyable.
After reading reviews and getting feedback (that I appreciate very much) that it would work with the 8 pin adaptor for my iPhone 5, I decided to order it.But...when using the adaptor, none of the controls and volume work and it sounds tinny. When using the recommended auxiliary cable, it does work but the JBL Flip produces much richer sound (obviously newer and better sound technology) and works seamlessly with the iPhone5--and is the same price.
I initially was informed of this product after a CNET review and I'm thoroughly impressed with the sound it produces!! As were my coworkers as many were inquiring about the price and model information after only one day of use! After opening the box, I admit I was very skeptical that such a small unit could produce anything but flat sounds. I'm a total believer as are my coworkers as they now ask me to use this unit with my Iphone or Ipod at work daily.
This speaker sounds great. Nice crisp highs and decent enough low for a small speaker. I like it a lot better than the JBL iPhone speakers. It sounds better and looks much better.I use my iPhone with it and listen to Pandora mostly. I would appreciate a radio attached and for the dock to work without having to take the (slim) case off of my iPhone. Other than that, no complaints really. I like the included travel bag.
One vital piece of info is missing from the product description-- it does not work with iPhone 4 or iPhone 5. According to the rep I talked to, no Logitech products support anything about iPhone 3. Why does Amazon sell this crap? !
Great sound quality and well made product. Definitely worth the price and I highly recommend this. Fits my iPhone 4 with the case on (the iPhone case, Incase brand, is pretty slim...one that I got free from Apple). My wife's 3Gs also works well although we have to remove the case first. Saved about $40 buying on Amazon over Best Buy. The only knock is that it is a little bulky, but that is probably the trade off for the great price.
It held up like a champ. Also at the party, after hearing it for a few seconds someone was convinced to go purchase himself one! And he doesn't even own an iPod or iPhone!One of my most satisfying purchases.Other notes:I use an iPhone 4 with a Speck snap-in case (from the Apple Case Program) and have no trouble docking it. The remote and case are nice additions, but I've yet to use them.
And if you've added a case to your iPhone, you'll either have to take the case off to connect to the dock or buy a dock extender. I put a dock extender on mine--$6 and the problem is solved.Revision of above review:Exactly 5 months (to the day) later, the speaker dock stopped working. The red light was on while it was plugged in (which shouldn't be possible) and it'd play for a few minutes, then suddenly turn itself off.
I purchased this item to sit on my nightstand to replace the other one I took to work for my office. I couldn't find one without a clock that wouldn't take up too much room on my nightstand. I read the reviews on this particular model some good and some bad, which is always the case but my only concerns was the size (length). If nothing else I could always send it back right.
Sent this to my sons family as a Christmas gift. Even on the outside of the box it said it works "Ipods". It wasn't until he read the owners manual that he found it would not run with his 4th Generation Ipod. Regarding business practices.........I paid $104, when he and I were reviewing the ad online, he in Virginia and I in Arizona, the price was $78. This was 4 days apart.
Answer: I did find a link on logitech's site (dated 8/2010) that confirmed "the new s715i" it will work with an iPhone 4. The box arrived from amazon and does NOT have an iPhone 4 icon (has the 3, 3G, plain old original, however, when I opened it, it did work with my iPhone 4 (it's a universal dock, fairly forgiving. My husband had the first iPhone with the free bumper and that sat in there as well, no problem. Because of "the new" language (is there an old s715i that doesn't work with the iPhone 4?), look for the 2010 copyright if you buy this elsewhere. Amazon is clearly shipping the current version but a store might have older stock sitting there. I think the 2010 copyright would mean you were safe.
