Overall this product was decent. I spent $10 more and got the SoundBot SB520 which I highly recommend. I had pairing issues with this Soundpal F2 so I returned the product

When they work, the sound quality is fine. I had a problem with the pairing disconnecting on occasion and frequent crackling and sound drop. This was even when the speakers were placed only a foot from the computer. I have not determined if this is a failure of Bluetooth or speaker quality, but it is annoying .
Only having one charger and not splitter to charge both speakers at the same time is ridiculous.
It was a good price, but you get what you pay for, and in this case it is not necessarily quality.

Soundwise, these headphones are pretty great. I have a pair of $40 Skullcandy earbuds and these surpass them in quality by far. Bass, midrange, and treble all sound good.

Pairing works fine with my Acer laptop. The first time I did it it was a little confusing, so here's what I'd recommend doing. Make sure the headphones are off. On the device you're pairing them with, turn Bluetooth scanning on. While that's scanning, press and hold the button until the light alternates blue and red (about 8 or 10 seconds). And voila!

If you're not getting any sound, you need to go into your audio settings and select Ausdom M06 Stereo as the default device. There's also a playback device called Ausdom M06 Hands-Free but in my experience that sounds kind of terrible. (I think that device actually plays the audio through the microphone.)

Even though the audio is great, there are a few glitches with my pair. Occasionally it will start to lag about a half-second behind the actual audio (which is annoying when you're watching something and the audio goes out of sync) and then skip back to the correct timing (which is frustrating when you're listening to music and it clips suddenly). When I first got these a few months ago they would do that a lot, around 20 times a day, but lately it's only been around 5 times a day that this happens.

I use Spotify as my primary music service, and the play-pause control doesn't work with it. Stop (pressing and holding) works, but not play or pause. I'm fairly certain that when I got them the skip forward/back buttons didn't work either, but now they do. (In Spotify the stop command does basically the same thing as pause.)

In WMP, all of the commands work. However, in whatever program, pressing the skip buttons causes all audio output to stop for about a second. This is annoying.

And there are numerous problems with the microphone. Namely, when it's on, no audio goes through. When I have gotten the mic itself to work, quality is pretty bad, with kind of slushy muddled random noise. If I don't have the M06 Stereo audio output channel selected, there's not as much feedback, but if I use the M06 Hands-free channel and have audio going, there's feedback. Suffice it to say I never use the mic.

There's a visible gap between the ear-pad and the back of the headphones, so even though these are closed-back, they leak quite a bit of sound.

TL;DR:
+Decent audio
+Relatively low price
+Comfortable
+Adjustable
+Lots of volume
-Leak sound
-Weird pairing instructions
-Skip forward/back buttons make audio cut out
-Mic bad quality
-Audio cuts out when using mic
-Useless "Ausdom M06 Hands-free" audio output device that confused me
-Play/pause doesn't work with Spotify

For such a small speaker, the sound is ok...not great, but not bad either.  A definite (major) step up from the ipad speakers.

The built in battery played for hours without any noticeable degradation in sound or volume.  Nice to have speakers totally independent of the music source or power.

My issue is with the pairing, which I suppose if i planned on using the speakers daily I would figure out.  There were no instructions on how to pair the speakers included, but were easily accessible on-line.  Good so far.  The instructions were clearly written by an engineer, most likely a junior engineer.  It took a while to decipher them.  To pair the speakers you need to push multiple buttons on each of the speakers in a defined sequence  for different periods of time, and then wait for beeps and flashing lights to tell you to move to the next step.  If you have the patience to deal with the pairing interface, the speakers may be a good choice for you.

Frankly, this is 2016 and I expect better interface.  I was successful maybe half the time; yes with practice I would figure it out, but why?  I ended up returning the speakers.

After returning this speaker I replaced it with the Sony SRS-XB3 (portable wireless speaker with Bluetooth).  Much happier.  Unless you absolutely need the "Ultra-Portable" cube size, and it is very small, the XB3 gives better sound in a slightly large package.  Buying 2 of the ultra-portables, they were a pain to carry around and as noted above, I had difficulty pairing them.  You may have a different experience.

As a basic bluetooth for music only, it works fine. There was initial audio noise, which required a Ground Loop Isolator. Once it was in the mix the audio is great.  That's about it for the Pros.

For the Cons...  Pairing in general is a pain. Every time you get in the car you have to pair it with the device. If you switch between devices each time you have to initially re-pair it it's a huge pain. push the bitton, hold the button, double tap the button, eventually after 10 minutes of hastle it will eventually pair. No, it's not just cuz I'm a dummy and cant fugure out how technology works. I'm an IT prefessional, and work with technology every day. This thing is poop when it comes to connection. Perhaps it needs another type of double tap.

Anything after the iPhone 4 loses of functionality with the button. All you get is hold for siri. No FFWD. It would be great to be able to skip tracks without having to touch your device. Kinda the whole point of the bluetooth wireless huh?

If I were to do it again I would likely spend a little more money and go with a different one.

It takes some time to pair them at times. Sometimes it doesn't want to do what you want it too, even though you follow the instructions. Very frustrating, but works well when it works.

Good overall...for the price.
Sound is seriously lacking bass, which I prefer there be more of. Leery of the whole "folding" aspect...could see them snapping/breaking very easily...so I not be brave enough to test that theory. Connects/pairs easily with my LG Android phone. Sound leakage is fairly significant...my husband can hear them across the room on medium volume. As far as using them for bluetooth communication on phone calls...they are terrible..!! Sounds like two tin cans connected by a string. So...if you can deal with the shortcomings, for the price, they are "fine".

Good size/sound for the money. Bluetooth seems to be interfering with the wi-fi, as when speaker is on, connection to router is lost.

The sound quality of the pair I received was subpar, bass was muffled and the highs had a hiss. The bluetooth connection also had problems, especially when moving or in my pocket. I checked into it and found out I had received a counterfeit pair. Check the YouTube videos and pics in these comments to make sure you get a legit pair. Amazon is giving a full refund but the hassle of sending it back still sucks.

UPDATE: I used my refund to purchase a legitimate pair directly from amazon. The sound quality is excellent, on par with ear buds from Bose, better than Beats. The bass is great, without too much boost. Gives it a very authentic sound. The highs/mids are crisp and clear. I haven't yet had any problems with the case that other people have mentioned. I only gave 4 stars because the fins are a little tricky, they don't always stay in the right position on the ear bud, and fit can be awkward depending on your individual ear shape. Also if you're like me and listen to your music loud, the battery life isn't as good as some other options.

NEW UPDATE: I lowered to 3 stars because the same bluetooth connectivity issues I experienced with the counterfeits I'm having with the legit pair. When I'm walking or running I have to hold my phone in my hand and no lower than my waist, otherwise the connection is constantly skipping. Now I will say my phone is rather cheap (ZTE majesty) and I haven't tried them with a better model like an iPhone or Galaxy, but I still expect it to work in my pocket.

Pros: Price is great. The sound is pretty good for the price. Handsfree calling feature is cool. Design is nice. Build is ok for the price.

Cons: Bluetooth gets choppy when you step just 5 feet away from the speaker.. I may have received a defective item but I don't want to risk getting a replacement.... Returning it for a full refund.

decent for the price. The sound quality is ok but starts to degrade when the battery is low. they can be kind of finicky when trying to pair with my laptop and I have to turn off bluetooth and it turn it back on again.

Bought two pair so my wife and I could work out together while listening to different music in the same room/area. Unfortunately, while mine seem to work okay (weak sound even when fully charged, slight hissing which I am to understand is from noise cancellation - which also doesn't seem terribly effective), hers had a host of problems ranging from bluetooth connectivity, charging issues, pairing issues, and the worst of all was sound quality.

The last, I suspect/hope is a defect. Whenever she turned her head the sound coming through would get garbled suddenly. Considering the movement inherent in exercise - or simply moving around with them in - these get a 1-star for it.

While the other pair hasn't had any major issues yet, I haven't had the time she had to really test them out. I've seen other reviews mentioning this issue, so be aware and test yours thoroughly while you can still return it. Anker's supposed to be good, but I guess they dropped the ball on QA for this.

I'd give these 2.5 stars if I could since I'm truly on the fence about them. Terrific sound when paired with another ZIPP for dedicated L and R channels and using WIFI to connect.. However, a few problems that have me considering returning/exchanging my speakers (especially after spending $600). When you try to use your speakers with your computer to watch video there is a SIGNIFICANT lag. The lag is not as noticeable if you only use a single speaker, but it's still present. Also, Bluetooth connectivity is really spotty. I've tried placing the speakers next to my computers/phones/tablets and the signal still drops off. This means if you don't have a premium account with the music streaming services (Pandora/Spotify/etc.) you'll be forced to use Bluetooth instead of WIFI which totally undercuts the functionality of the speakers.

I like it when it works! For some reason it will not re-pair after resetting with the my Bose Soundlink wireless headphones. I follow instructions on both devices to the letter and nothing happens. It's driving me crazy.

had a lot of trouble pairing. did not have a good sound

They don't always connect to my bluetooth and I haven't quite figured out why yet. Also, when they are connected, they occasionally stop transmitting and using touch function is spotty. The sound and profile are very nice. I would have given them a five if they worked all the time like the do most of the time.

Paired easily and sounds good.  Good for the price.
