Their sound is very clear and has good bass.
Their battery life is enormous.
They are resistant to moisture and sweat, which is not common in earbuds.
They are lightweight and have a very good fit without causing discomfort or the risk of falling out of the ear.
They connect instantly and do not have any issues with disconnections. Instant disconnections only occur when I need to go to a neighboring room. In a test we conducted in an open space, we had to move about 40 meters away for them to disconnect from each other!
For calls, either one of the two can be connected, which is convenient for those who are used to wearing only one or when one of the two is out of battery. At some point, we tried connecting them to separate devices, one for speech, and they connected without any problem.
They automatically disconnect from the mobile when I put them in their case for charging, as long as they are not out of battery.
The microphone would be better if it had noise cancellation. Sometimes my callers complain that they can't hear me very clearly. This mainly happens when I am in open spaces with moderate noise. However, there is no problem in closed spaces.
They do not have the ability to connect to multiple devices, so when I want to connect them to my laptop, I have to disconnect them from my mobile. It doesn't bother me, but it would be more practical if they had this capability.
While normally they disconnect from the mobile when I put them in their case, if the case is out of battery, they continue to stay connected, resulting in not only their battery draining, but also no communication when I answer a call from the phone. Fortunately, this is not common because the case is sufficient for 2 full charges of both earbuds, so at least a little battery is almost always available!
Today, 24/03, after 2 months of use, the button of the right earbud broke and I have to go through the process of replacement/repair.
In general, I am very satisfied with the earbuds and use them very often, sometimes for hours. The only thing that concerned me is that they developed a defect very quickly. They will definitely replace/repair it due to warranty, but I hope I just happened to get a faulty batch and won't have the same problem again after 2 months.
P.S.: Before purchasing them, take a look at the official website of Creative Europe, as they often offer them at a good price.
Update:
25/03/20 I contacted Creative.
31/03/20 They sent me a prepaid return label.
09/04/20 I returned the faulty ones.
24/04/20 I received the new ones (fortunately, it was a replacement and not a repair).
29/04/21 Another replacement was made due to the same defect, very poor quality, I would not recommend them!
