## Questions & Answers

**Q: has anybody swam with these multiple times?  do they work/survive it???**
A: I have not personally done this, but IPX7 rating is pretty specific (quoting from Wikipedia):  Ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1 meter (3 ft 3 in) of submersion).  So I would say if you're swimming laps or something that doesn't require you to exceed the 30 minutes per session and not going under more than 3' they should be good for repeated use.  As far as survival, I'm not sure.  Water can attenuate the signal, but it should be safe to try it out, within the restrictions above.

**Q: I’m having trouble getting them to connect together when I first got them they were fine but after I tried to just use one they would never connect**
A: Please try to restore to factory settings:
Hold down the MFB button for about 6 seconds during charging,
until both LED indicator flashes with blue light 3 times to restore the factory settings.
First make sure that Bluetooth is off for all Bluetooth-enabled devices, 
then take earbuds out of the charing case at the same time, earbuds are on and pair with each other automatically,
meanwhile, the blue light of the left earphone disappears, the right earphone red and blue lights flash alternately,
now turn on the Bluetooth of your phone, clear previous "TWS880" connection records, search and connect again.
If it is still not work well, clear record repairing "TWS880” again. please try more than a few times to succeed.
Please feel free to contact us through Amazon message or here for any additional information needed.

**Q: Do both ear buds work when talking on the phone?**
A: These ear buds work to hear your phone call but I have never been able to talk on the phone with them. The other person cannot hear you using these

**Q: How is the phone call quality?**
A: I immediately tested these with my mother on the phone, who is a bit hard of hearing.  She could hear me well outside and I did not sound muffled to either of them.  I also did a recording test and found the recorded sound to be pretty good, not better than the iPhone's built in microphone but certainly better than my LG HBS-820 or the HBS-920 (my previous headsets).

## Customer Reviews

### ⭐⭐⭐⭐⭐ **EDITED REVIEW
*by L***A on November 9, 2019*

So - to edit my previous review, the customer service is amazing! DuoTen reached out and sent me a new pair of headphones right away when they discovered I was having issues and after getting to try them I haven't had ANY of the issues I experienced with the original pair. The earbuds both lit up when replaced, and synced easily to my computer in a pair. When I used them, I didn't experience skips or buzzing either! I'm pretty sure I just happened to get a faulty pair last time - and that was easily replaced!--------------------------------ORIGINAL OLD REVIEW:So far I have a love-hate relationship with these earbuds. Setup was complicated. For the longest time, I couldn't get the left earbud to work at all (show red light for charging, blue/red to pair, to pair/connect ANYTHING) and I was about to think I had a broken/defective set. However after resetting twice and fiddling I finally got both to show charging RED LED's. However THEN I couldn't get them to pair together. Another half an hour and resetting them again before they were finally in twin mode and connected to my laptop.When I finally got to try them out? They were great!! The sound quality was pretty good (above my skullcandy earbuds, below my Sony Wireless Pulse Elite headset I used for gaming), but they were also so comfortable and of such a good quality that sometimes I forgot I even had them in. Now - I also have had a few issues. Sometimes there's crackling/static sounding noise that comes from them which is a little annoying and makes the sound a bit less clear sounding. ALSO, one of my biggest issues with these so far is that either side randomly will fade out and then back in. Or cut in and out. There's no rhyme or reason for this, and I thought maybe it was just because they hadn't charged enough, but I allowed them to charge all night while I was working and when I came back they still did this. I'm also not completely a fan of the 'touch controls'. I'm a little afraid to use these with my phone as I'm /sure/ i'll accidentally end up calling someone.I'm going to give these a week or so and see if I can't work out the kinks because I really do want to like them! The case is nice too, small and lightweight with a magnetic clasp. However if I can't get them to stop randomly cutting out then I might as well go back to fighting with tangles and being tied down by cords.

### ⭐⭐⭐⭐ Surprisingly good sound for a very reasonable price.
*by D***W on March 24, 2020*

I'd give 'em 5 stars if it were not for the fact that the first pair I ordered came with a defective case. (One symptom: After fully charging case and earbuds and disconnecting from the power adapter, the case battery would run down completely within a day even with no use of the earbuds. Other strangeness as well.)Note that these do not have active noise cancellation. The CVC 8.0 standard they advertise is a different sort of noise cancellation that refers primarily to what the microphone picks when you are making a phone call. It has no impact when you are playing recorded sound. So the noise cancellation claim is very deceptive for those who actually want active noise cancellation. (I actually prefer being without because I walk on streets in my neighborhood and I want to be sure that I can hear cars coming from behind me.)The "27-Hour Uninterrupted PlayTime" claim is false. The case plus buds may be able to hold enough energy to support that much play time without getting back to a power adapter. However, after a few hours of listening, you still have to put the buds back in the case to get a new charge. That strikes me as a substantial interruption. There is no good reason for making a claim that clearly seems to imply something else.In spite of my criticism of misleading claims about the product, for my own use, I am very happy with it. They are much more comfortable and sound better than the Soundcore Spirit X Sports Earphones I bought a couple years ago. (They still work, but the over-the-ear hooks and the wire that connects the buds are unnecessary annoyances.)I have made no attempt to use them with a phone to make or receive phone calls, so I cannot comment on that.The main complaint I have for my own use is that using the earbuds to control volume is so tricky that it is hardly worth attempting. I just use my playback device. I wish they had a no-phone mode, as that would allow a much simpler set of gestures for playing media on a tablet.(When I determined that I had to return the first (defective) set I received, these were no longer available. So I ordered another similarly priced product that appeared to be similar. (Pasonomi, TWS, IPX7) The sound for them was surprisingly poor. Very tinny. Unfixable with an equalizer. Furthermore, even though I could use them with two different Windows 10 laptops, my Amazon Fire Tablet could not even see them, let alone connect. Fortunately, when I scheduled the return for those, these had become available again.)Update: After using them for a while, I have encountered some annoyances (which are independent of the sound quality). I have discovered ways to deal with them that I will share here.If you pause your playback, then, after something on the order of five minutes, the buds will announce "power off" and do so. There is then no way to get them to reconnect without first putting them back in the case. The result is that, on my daily walks (when I am always using them), I have to take the case along because I often pause playback to have a conversation with a neighbor. The fact that I have to through the process of putting them back in the case before I can connect again is very inconvenient. Nevertheless, I do still occasionally make the mistake of letting them die this way.When you disable Bluetooth or power down the device they announce the disconnect and go into the mode of looking for a device to connect to. Oddly, they will keep doing that for a lot longer than it takes for a shutdown to occur (as above) when they ARE connected. Furthermore, if you put them in the case when they are in this state, things can go wrong. I've had them connect while in the case. I've had them run down the case battery. The only way I have found to avoid these problems is to make sure that they have powered themselves off BEFORE I put them in the case. There will be no LED on or blinking when they are really off.
