These are good headphones. They are not a set of $100 plus headphones but they are good. They connect flawlessly and the basic functions work as they are supposed to. The sound quality is good. They are on little on the bass-heavy side, so it makes them fun to listen to. They do not have a flat sound. These still have a good amount of mids and highs to sound good. They also get pretty loud. If you buy these, make sure you try all the ear tips to find the one that fits your ear but also sets the headphones correctly. If they don't sound good, then you don't have them in your ear correctly. The case for these is fine. One person wrote that it is hard to open but that is not true. pull the case lid open from the top -not at the seam- and it folds open very easy. Now, I will say getting the headphones out of the case is a little cumbersome but only a little. for $15 to 20 these are a good value.

These earbuds arrived after a long wait, and right out of the box, the charging case was completely depleted. I own several high-end and mid-range earbuds from well-established brands, so I have a solid point of comparison.
After finally managing to charge the earbuds, I gave them a listen. To be fair, the sound quality was surprisingly good, with a nice low-end response. The earbuds also fit securely in my ears and didn’t fall out.
However, the design of the case is poor. It’s extremely slippery, making it frustrating to open. There’s no grip, latch, or indentation to easily lift the hatch, and pulling the earbuds out is unnecessarily difficult.
It also took an unusually long time for them to connect to my iPhone—my second warning sign. Still, since the sound was decent, I gave them a chance and left them charging overnight.
Unfortunately, by the next morning, the case was once again completely dead. No charge whatsoever. That was the dealbreaker. And to make matters worse, the awkward design caused me to drop the case, and one of the earbuds popped out. It took me an hour to find it since my locator app couldn't detect a completely drained earbud.
That was the final straw. I returned these earbuds and moved on. Save yourself the trouble.

Case is poorly design the lid, when open impedes inserting or removing the ear buds. Also, it is so smooth it is hard to open, nor is there any lip or something to get a grasp on the lid. The sound is ok, These are not 28 hour play time, they are only 7 hour as the manual says but 28 hours with case and volume at 50%.

Does Not Work - Do Not Buy

I bought these for the sole sake of having earbuds on the go, and I figured for an affordable price, they'd actually be decent, but no. They don't work. At all. I've done everything possible to charge them, to activate them, to try to manually activate them, and nothing works. I've been ripped off of my hard-earned money, and I'd highly advise against buying these.

Always cutting off. Without a reason as to why, it just says "powerw off." Even when fully charged.
