Question: Does it use APTX bluetooth technology to connect?   Is the sound quality more "open" than the Bose Soundlink II and the Mini?   Where can it be heard in Atlanta?
Document: Samsung did a very good job. The design of this speaker is excellent with very nice tuned passive bass radiator. The results is close to magic for a speaker system of this size. I have compared it with the Bose Soundlink II and Bose Soundlink Mini and honestly this is a better performance speaker in all the sound spectrum, and surprising cheaper. What it is important to know is that this is not a speaker for high volumen reproduction, nevertheless it performs extremely well for backyard or pool easy listen.
Pairing is simple via NFC. Just hold your phone up to it and it pairs automatically. Bluetooth pairing for non NFC devices is fairly simple as well. The only down side is that you can only pair one device at a time with this speaker. The only other downside is that this speaker does not allow you to talk through it for calls. However the Bose Soundlink does not allow this either. Still more than worth it for the better sound quality with the aptX support.
Didn't like this at all. received a used one - open box - but still not happy with the sound. Metallic sound and lots of small sounds from bluetooth disturbances. Read a lot of reviews now after I returned it and apparently it is a common problem with this speaker. Bought BOSE from Amazon instead, the mini speaker outrageusely good. Buy it instead if you don't need NFC.I did and I am VERY happy!
If you asked me which portable speaker is best, until now i would have let you decide between Bose Soundlink, Big Jambox or TDK A33. But after having heard the Samsung DA-F60 recently, i would definitely recommend this over all the others.Sizewise the Samsung is nearly identical to the Bose Soundlink. Also weight is similar. While the Big Jambox is considerably bigger, the TDK A33 is a bit smaller.The sound coming out of the Samsung DA-F60 is really rich, full and brillant.
The sound quality also benefit because the use aptX coding over the bluetooth link. The NFC woks very well with my samsung Galaxy S4 you just touch the speaker with your device and go. Highly recommended.
I have been keeping tabs on this device since it was announced at CES 2013. When I saw it on Amazon, I got it as soon as I could. I had been in the looking for a portable Bluetooth type speaker since the holidays 2012. I had narrowed it down to the Jawbone Big Jambox or the Bose Soundlink. When I was about to make a purchase, this Samsung speaker was announced so I decided to wait. I am so glad I waited! The sound is rich and full.
If you like treble and always thought the Bose sounded too muffled, I would take a look at the Samsung. If you like the deepest and strongest bass from the smallest form factor, i would probably go for the Bose.Ps. 2 days ago the new Bose Soundlink Mini was announced.
Original comments:This is a nice little unit that has great sound. It is a little tricky to connect to the first time with each appliance (I use it on 2 iPads, 2 iPhones, and my MacBook Pro), since you have to remember to push the function until in blinks.
the Samsung seems exactly spot on. There is a Bassboost-Button, but to tell the truth I hardly heard any difference between on or off.Vocals sound fuller on the Bose, they sound a bit thin on the Samsung, but this is nitpicking and overall there is nothing to really complain about soundwise. Only at high volumes the sound starts to suffer, but neither the Bose sounds really good at highest volume levels. The Samsung vibrates though with stronger bass notes.
It does not automatically remember the pairing as my car does.EDIT AFTER 2 MONTHSEach time I use it my rating goes down. Deep base tones  are flat, bams. Now I'm looking for troubleshooting instructions since it refuses to connect to any device. It shows up, but comes will not connect.EDIT AFTER 4 MONTHSWhat a disappointment.
Answer: D. Lang-I just ordered one.  I will review it in a few weeks Let me know if you have any other questions.I know what you mean about "open" quality.  You and I seem to have similar tastes in speakers.  I have some wonderful speakers already and I am looking forward to this Samsung.Jim
