amazing device, i used many Bluetooth devices earlier, but the quality of the voice during calls was very bad this one is perfect, the device is pretty small with a very nice shape. you can adjust it as you wish.
i used it  for one month all was perfects, suddenly it stopped working , i contacted the MAOZUA support and really i never expected such support. they immediately dispatched a new device for me and again it working perfectly. with such customer support i will never be worried if anything happen again.

I bought 2 of these and I could even connect two PC's or the PC with my cell phone for Active Sync from different floors in our office building! I have a bluetooth mouse and other bluetooth devices and I am very happy with the performance of this product. I chose the class 1 for range and it was worth the money - I turned off the internal bluetooth and choose to use this USB device due to the improved performance and reliability. I really got my money's worth (I bought 2 for less than I paid for one of the earlier version 9 class 2 device).

This device not only saved me money but also made my Logitech speaker useful again. It was so easy to set up, I didn't even need the simple instructions enclosed. Once paired with my iPhone 6, this device and the speaker sync with my iPhone 6 right away when I turn the blue tooth on my phone on and off. I highly recommend this device to anyone who has speaker with the old connector. The only minor thing I encounter is whenever I turn my blue tooth function on my phone on or off while the paired speaker is on, the speaker makes a loud sound. Therefore, I try to remember to turn the speaker off first before I turn off my phone's blue tooth function.

I have used many Bluetooth devices but ne compare to the blueant HD I would recommend it to anyone who enquire about it. Good product

This device is fantastic. The fact that it can be set up in the car once and easily used without fuss or setup every time the car is on, is what makes this more useful to me than other Bluetooth receivers I've had.
*If you're like me, and are a "sound snob" you'll definitely want to get the adapter mentioned in previous reviews, as this unit does put off a high-pitched (but almost unnoticeable during loud song) feedback. A simple 3.5mm adapter with a male end and a female end should fix this.

This is a bluetooth transmitter, which means if you connect the transmitter to another device such as a, PC, Laptop, tablet, some Ipods it will turn your non bluetooth device in to a device that has bluetooth, meaning they will connect to a bluetooth speaker or headset.

What do you get, the units is very well made, Im always impressed with the quality of Aukey gear, have had a number of bits and everything has been better than the price point would have you believe, you receive
Aukey BT-C1 Bluetooth Transmitter
3.5 mm Female to RCA Male Audio Cable
USB Cable for charging
User Manual

Wanted to connect bluetooth speaker to a PC, which was very straight forward, pairing took no time, If you are familiar with bluetooth and pairing it will take you no time.

I connected the transmitter to a PC and bluetooth speaker and it worked superbly well, the sound was uninterrupted with no loss of quality.

Im really pleased with this device, its possibilities are endless, you can connect it to the TV and upload photos videos via bluetooth to the TV, connect the old Hi-Fi to your latest smartphone etc, for the money its cracking value

This is absolutely amazing! i have a relatively new car that would have cost me extra to have Bluetooth or even an aux cord integrated in so i settled to the cheap alternative of using those awful fm transmitters that wouldn't work i went through 4 or 5 before i finally went and bought one of those cassette to 3.5mm adapters and that was also bad as well. So i looked online and found this neat item. I have to say its great! ive been using it for 2 weeks and ive had no problem whatsoever with it. Easy to use, first you plug it in to the cigarette plug or whatever they call it lol and it displays a channel for you to switch on ur radio to. You can change the channel to whatever you like. From there you can connect it your phone via bluetooth or you can connect via aux cord which is nice also (aux cord is included in the package). After that your good to go! Start play music and bam you can now play music via Bluetooth in ur car without having to spend big bucks replacing or modifying anything in ur car its just plug and play! Another added bonus is you can answer a call, end a call, redial a call ,next track. This is great for you to answer calls on the road without being distracted by ur phone in ur lap or having a bluetooth headset in ur ear that might always fall out. i tested the calling feature many times and asked if the sound is clear to the other person and they have no problem hearing me whatsoever. So if you are looking for an inexpensive way to transform your car this is a great product

This thing is AMAZING and I am kicking myself for not having discovered these gadgets sooner than I did!  Wireless connectivity is relatively reliable 2 rooms away - it matters how many other connected devices are using bandwidth at a given time, however - just like any other wireless device. Netflix and HuluPlus and You-Tube work flawlessly but other, less-popular streaming apps seem less stable and quite glitchy.  Fortunately, there's a work-around for that so it's essentially a non-issue!  This thing is small and doesn't clutter up precious space like a tablet, laptop or computer would - the biggest bonus is that it uses Android apps that aren't available on those other devices yet has all the apps you've grown to love and appreciate on your PC!

Update: April 14, 2015.  I order this device exactly one year ago today.  Up to recently, it worked wonderfully.  I noticed a couple of weeks ago, there was a power "glitch" and I lost all function.  Then, suddenly, I touched something just right and I had function again.  So, for a couple of weeks, it's been business-as-usual and I'm a happy camper.  Until today...another power glitch and I got nothin'.  The difference between a couple of weeks ago and now is that the power's on but I've got no interface and no way to control the device.  It's basically useless with no way to fix it.  For as much as I paid for this thing, I would expect it to last a lot longer than exactly 365 days.  But, I suppose I should count my blessings:  given some of the other reviews I've read, my device has held out quite a bit longer.

I spent 2 days scouring the internet for a resolution to my problem and finally came upon some extremely obscure YouTube video that showed how to do a factory reset on a bricked device.  I followed the instructions and voila - was able to boot it and restore it.  Of course, I lost all of the data I had accrued since I started using it, but that pales in comparison to having a device that doesn't work at all.

Still no response from the Seller with regards to any amount of customer service - just wanted to know if they could help with a fix for the device - I guess not.

I still like this device, but if I wasn't a persistent, semi-tech-savvy kinda person, I would have a piece of useless junk here - and I know that there have been others who have probably encountered this situation who didn't know what to do or where to turn with their issue so they just junked it.  There should be better customer service for the products we purchase - not just here, on Amazon, but ANYWHERE.

Only problem is that if I connect more than one phone to it, only the first one to connect "wins." Don't know if that's a Bluetooth issue or a headset issue. Other than that, this device is incredible. It runs for about 3 weeks for me with regular use - meaning 2-3 hours of calls and 5-6 hours of standby, 5 days a week. It's so good I even use it sometimes in my off hours to listen to music.

The retractable earbud design took some getting used to. I also was concerned, for a while, that the mechanism would wear out. But it still works fine.

One wish: that the LED showing "call in progress" was more prominent - perhaps on the top of the band, and brighter. As it is, coworkers can't tell if I'm actually on the phone or listening to music when I'm at my desk.

After a few years of mediocre experience using various bluetooth products, I wasn't expecting much from more recent music-audio based devices.  But I think that's changing, either because of this company (Anycom) or because of Bluetooth 2.0 EDR (Enhanced Data Rate)

I currenty have the above device (BAR-10), an Anycom FIPO (which plugs into iPod-based speaker systems) and a Sony BT adapter for an iPod.  I also have a Samsung Q1 UMPC that is kind of my 'Super iPod'.  All of these things support EDR (or are listed as having 20-20,000Hz frequency response) and work together quite nicely.

The BAR-10 is always in pairing mode, so there's never any link-up hassles.  The best part is that the audio sounds very good.

I would recommend any Bluetooth 2.0 EDR product from Anycom and will be getting another BAR-10 soon.

I love this bluetooth adapter.  I use it every day in my car with my iPhone 5.  Turn on BT on the phone, turn on GOgroove and I've got my Spotify music through my car speakers.  I love it!  (after the initial 'pairing' I've never had to re-pair.  Just turn on phone BT, then GOGroove and instant connect.  Your mileage may vary.)

You do have to hold the power button on the GOgroove for...about 3 seconds? for it to turn on.  Not a deal breaker.

Battery life is ridiculously long.  And that is without actually turning off the GOgroove.  I often leave it on, taking my phone into work.  Not sure how long it stays on, but it apparently has an auto-off which just makes me love it more.
A MUST have for people who like having their music wherever they are.

This amazing little gadget gave new life to some old Bose headphones. That I now use as Bluetooth headphones. No need to buy the expensive new Bluetooth headphones especially if you invested a good amount of money on some "old school" wired headphones. The volume on this thing is pretty loud and battery life is outstanding lasting me 5 hours at least.

This is probably the best device I've bought in a while.

Pretty darn impressive.  Since I use the phone every day for work and for personal use in my vehicle and the vehicles built in Bluetooth was worthless, I decided to purchase this one based on the reviews.  It does not disappoint!  It easily connects to two phones simultaneously of different OS - Apple & Android.  If I receive a call before I've turned the power on, the SuperTooth Buddy will connect quickly enough and answer the call with the push of a button.  Very slick.  Another benefit.  Let's say you walk into a store out of range of the SuperTooth.  When you return you will hear the SuperTooth beep letting you know it just reestablished the connection to your phone(s).  Another huge advantage of this is the mount, which is a very clean design.  There is a small clip that clips to your visor.  Both sides have a large inset where the SuperTooth's magnet will click into place.  So no matter what orientation you have your visor, up/down or swung over to the side window, if the SuperTooth ends up on the wrong side just pull it off and let it snap into place on the other side within seconds!  Also, the charging port is a standard micro USB instead of some proprietary connector.
I dropped one star because the noise reduction is not "the best" but for the money it's great.  This thing isn't perfect by any means, but I have to say I own around 4 different Bluetooth headsets and this was great addition and it kept me from having to have one stuck in my ear the entire day.

June 5, 2017  UPDATE:
Its been 1  years using this device roughly 10 times a day for 5 or 6 days a week.  I often remove it from the car and stick it to the machines that I am working on so I don't have to use my BT earpiece.  Ive dropped it at least one time and it has been exposed to light rain.  Although Im careful with my electronic devices, this little guy has been through a lot just from heavy everyday personal and work use.  Like the Energizer Bunny, it keeps going and going and going.  The volume and clarity are still great.  The battery life is nothing short of amazing.  If I could give it 4.5 stars I would.  Still the only slight reduction (.5 of a star) is for lack of sophisticated noise reduction, although it truly has NOT been a problem.  If or when this ever fails me I will purchase it again in a heartbeat.

When I ordered the Jumbl Bluetooth 4.0 I've already ordered all kind of Bluetooth listening devices because my none headphone jack iPhone 7 was already on its way and yes I also got great Bluetooth headphones to, but before all that I invested in 2 pairs of none Bluetooth expensive headphones and I really didn't want them to go to waist, so a Bluetooth adapter seemed like a perfect answer but because I never tried this technology before I decided to get all kind of adapters!
Luckily they are not expensive and almost my whole family were also expecting iPhone 7s (  6 not including mine ) so I ordered 10 different Bluetooth adapters knowing that they will make nice gifts later.
All I can say is that they all worked pretty good but none got close to the Jumbl 4.0 which partly because the 4.0 Bluetooth built in the controls worke perfect with the iPhone ( I mean, Start, stop, Volume up/down, Voice Calling, Forward and rewind, and even Siri if disconnecting voice calling in the phone settings which let you do a voice calling through Siri if you wish or many other things like playing a certain song as a small example of the possibilities ).
The only thing that worried me was sound distortion but surprisingly the sound on Jumbl Bluetooth 4.0 sounded and still do amazingly, I couldn't tell the difference trying with the none Bluetooth adapter that come with the iPhone! So good that out of 2 $300 pair of headphones I decided to  cut and shorten the wiring by almost 2 feet on one pair, soldered a gold 3.5 headphone jack professionally this way I don't have all the loose wiring all over me, I love it and every thing about it.
Conclusion: I recommend and I paid full price unlike those who get stuff for free so they can give a good advertisement for their products.
  The only thing I can't testify about is the battery and how long it will last but by now I've been using it pretty much every day, charging at least twice a day and I haven't seen any changes since day one and hoping it will last and if not I'll for sure buy another unless the company will come out with an even better product but with those prices it's really a simple choice.
