Question: Which Bluetooth version is it? 4.0 or older?
Document: Looks good, smaller size than what I had expected, but the sound is amazing.I have this model and the later model &#34;SHARKK Portable Bluetooth 4.0 Mini Speaker&#34;, I like this model more, since the aluminum give it a higher feel/quality.
So far, this is a great little speaker. Sound quality and bass are very good for the size. I chose this one over the newer bluetooth 4.0 model because of its micro SD card.My only complaint so far, is the absence of a shuffle mode when playing off the SD card. That would really improve the experience.
I did quite a bit of research online before purchasing this item. I'm upgrading from another older portable speaker that only had aux in, but had good sound quality for the price.The SHARKK speaker has impressive bluetooth functionality, was easy to set up and easy to control.
I must say the design is the best feature from this product-small, elegant and sturdy.+Function: Sharkk really went a long way and put a lot of thought in making this product as convenient and suitable for any users, any occasion as possible. The speaker comes pre-installed with Bluetooth 3.0 to connect to your phone/laptop wirelessly.
Used it for one day and I'm blown away by the clarity and power this little wireless speaker produces. Oh, did I mention the battery life was still OK even after 4-hours of playing right out of the box. Bluetooth range is a little weak, but not a deal breaker. Get one.
I've had quite a few portable speakers and this one is definitely the best. It's incredibly solid and has nothing on it that can break (since doesn't open/close). You can throw it as-is into a backpack and not worry about it.The sound is terrific: it can go very loud without any distortion.Battery life is decent. At least 4 hours playtime from a full charge while using bluetooth.
This product is fantastic! I use it as a bluetooth speaker for my Google Nexus 4. The construction is solid; it's metal except for the black plastic along the bottom where the controls are. It paired up immediately with a Nexus 4 and a Samsung Galaxy S3. The sound is surprisingly good. For the size, there is great bass response without muffling the highs too terribly much.
Bought this right before a trip with friends. All my buddies could connect thru bluetooth easily and play their music lists from different phones (iPhones, Androids, Windows). Surprisingly loud and clear for such a small speaker. I would've given 5 stars but the battery time for me was about 4 hours before needing recharging and it took several hours to recharge.
As currently configured, it is somewhat awkward for larger fingers, especially in low light situations.Overall, I am very pleased with the SHARKK Bluetooth Speaker and give it 4.5 stars (I would if I could above) with .5 stars subtracted for the contol buttons. I recommend this highly as a surprisingly good bluetooth speaker in a small package.
It packs a little punch for the size. I was very happy with all of the &#34;extras&#34; that this device has that others do not, for example, microphone for taking phone calls, and micro SD card slot for music.I would suggest this for parties and other things, but if crisp and clear sound via bluetooth is your thing I would suggest a little better version.
Answer: Yes.  Just checked and my Bluetooth says 4.0+HS.  When the Bluetooth signal is strong, the SHARKK reception exceeds the 50 feet advertised by 30 additional feet and the audio is sharp and clear.  When the signal is not so strong, you may get some distortion and even disconnects.  The SHARPP will continue to try to reconnect.  Sun flares seem to be behind the disconnects.
