Sound quality great
These are the smallest earbuds I’ve found which is a big thumbs up for me bcos I’ve got very small ears. They also have great sound quality. They’re a big must buy EarPods, you won’t be disappointed.

Worst earphones
Don’t buy it! Quality is terrible, it feels so plastic and cheap materials, not only that, it is very fragile and with just one time falling from your ear, it will tear apart. Sound is ok, but not close to be the best compared to many other with same price. One of the earphones doesn’t charge up. I put them to charge but only one of them charge. I have bought many earphones before but I will say it is one of the worst. I don’t recommend it at all.

They work independently and have a long battery life.
Surprisingly long battery life for such a small ear bud. Fits perfectly and the sound quality is excellent. I like to listen to audiobooks while working with my hands and these are perfect for it. The buds work independently, as I only use one at a time. Would last a couple of days with out needing to charge the base unit. One downside is that the lid of the base unit seems a bit flimsy and I have a feeling it may break. Also good for listening to audiobooks while sleeping either. I’ve read other reviews before I purchase these and some say the they’re mot great for music, I listened to music on them and seemed perfectly fine. But I’m not a music fanatic. 9/10

Decent little earbuds at a decent price
i very much love these ear buds. ive had to use a bit of tape to stop the case opening in my bag. but i can live with that for the decent quality and battery life.

Not invisible and quite uncomfortable.
Bought to use at work but they aren't invisible and they aren't very comfortable and they move in your ear easily so you have to keep adjusting them to be able to hear what you are listening to.

Great earbuds for the price but only lasted 6 months
They're great easy to use things, had no issues with connection or anything and the battery life is great, I use one ear at a time so they can last me around 8hrs a time :) I've used them daily for 6 months but now the sound is getting quieter and quieter :( a shame as these were great.
