Question: Nano 4g compatability? Does anyone know if this works with the new Nanos (4th generation)?  Will it charge it? - that's the problem I'm having with my old dock - it connects a plays fine, but won't recharge the ipod.
Document: I wanted a small ipod (I have a 4th gen Nano) speaker dock for my kitchen and for that purpose, this is fine. I do have several complaints that I saw mentioned in other reviews. One, there's some annoying sound distortion in songs that are heavier on the bass or where the singer has a lower voice. Two, sometimes my iPod charges while docked, and sometimes it doesn't. I can't figure out what to do to get it to charge every time I dock it.
We own the JBL One Stage Micro Portable Speaker Dock and it sounds good for its size. However you need to realize that it's a very small unit and it can only do so much with speakers that are only about one inch in diameter. It looks very nice and it comes with a nice carry case for storage and travel. The unit works really well with the Ipod Touch and also with the Ipod Nano 3rd Generation. It will charge either unit with no problems.
PROS:-I was a little worried when buying a new iPod Touch 2G since firewire  charging was disabled with this new generation as I had heard numerous other docks had lost their charging functionality-- thus I was quite surprised when I saw the charging icon when I docked my new touch! Since the iPod touch charges, I would assume the new 4G Nano will charge as well.-Wonderful sound in such a small package.
Wanted something to play my IPOD Touch around the pool. Gets pretty loud considering it's tiny size. I use it mostly to listen to audio books. At higher volume there is a slight vibration and it does not charge my 2nd or 3rd gen touch or an old 3rd gen nano I jave laying around. Also does not include a docking adapter for either nano or touch. It has a single docking adapter but I don't know which type of ipod it's for, but it sure isn't for any ipod I have.
This was a birthday gift in May for my new 3G iPhone. It worked beautifully at first, althought at some point I noticed a message pop up when I attached my iPhone stating "This accessory is not optimized for this iPhone." By the time I looked at the packaging more carefully it was too late for a full refund, so I'm still using it. It does seem to charge my phone, and the remote works with it.
I love this little doc but for one issue, which is the upper level sound quality. If I turn it up enough to be heard when I'm working in my home office (which isn't all that far from where the unit sits in my living room, the sound gets fuzzy. Other wise, if I put it down to a comfortable level for the room the unit is in, it works just fine.JBL On Stage Micro Portable Speaker Dock for iPod (Black)
If you have a Ipod Nano 5th generation, you might be surprised to find that this unit does not charge the Ipod!! !
The red color is more like a dark magenta, which I liked even more.The speaker supplies adapter pieces to dock your nano or shuffle. I have the nano (2G) and tried to dock it using the nano adapter but, the adapter is too narrow so it's useless. Docking the nano without it works fine.
I haven't used up the batteries I first placed, so I don't know if the claimed 24 hours of battery life is true-- doesn't really matter for me since I keep my dock plugged in most of the time, but for those who useit frequently on travel, it may be a nuisance to carry around the power brick (which isn't much larger than a pack of gum).-I'm not sure if the USB out actually works for synchronization.
I like my music clear and crisp and often loud enough to hear in a large room or patio setting with guests all around. This does the trick. BTW, nano 4th generation compatible (as well as two others I've tried).
Answer: Hello.  Yes, the JBL Sound Stage Micro does support docking and charging of the Apple Ipod Nano 4th generation.  I know because I have one and it charges fine in this speaker dock.
