Review: Highly Recommended Earbuds - I would describe these earbuds as ‘exceptional’. Prior to purchase, I did a lot of research online to try to find the best earbuds to suit my needs. I’d been having issues with some others I had bought that kept falling out of my ears, and also caused pain after wearing for a time. I saw these Soundcore 40i earbuds in black under review. The video said they were an improvement on the 30i, which I had also considered. When I clicked the desertcart link, I was pleased to find that the item was available with a £20 off voucher. Not only that, but the earbuds were also available in a lovely shade of gold; much more appealing to me than black. As a Prime customer, I was able to have them the next day. Earbuds duly arrived and I was excited to try them out. They were already charged and ready to go, which was great. Just a point of note, the charging cable is only short, which might be an issue for some. The design oozes quality. After a quick read of the quick start instructions, I was able to pair the earbuds with my device easily. The sound quality was as I’d hoped. I used them for the first time at length today at work, and wasn’t disappointed. The most noticeable thing was the comfort, I could hardly tell I had them in. The earbuds did come with some clear covers to adapt the earbuds if they were too small, but they were actually a perfect fit for me without them. I move around a lot in my job, and they never once fell out or even moved in my ears. We are only permitted to wear one earbud at work for safety reasons. I was amazed that the charge on a single earbud lasted for the whole of my 6 hour shift, I would normally have had to swap to the other earbud halfway through my shift. I really liked the button control on the back of the earbud. I was able to pause, restart, increase the volume (right earbud only; left earbud decreases volume), and skip to the next track. So, overall I am very happy with my purchase and happy to recommend to others.
Review: Quality and value. - These are great so far...sound is good, they never fall out ( unlike ear pods which I can't keep in), good battery, comfortable and great value. This is my second soundcore product (I also have headphones)...they're as good as I need and I don't see any need to pay multiples more for some of the bigger name brands.

Interesting way to listen to the music. Sound is good. I would not recommend if you are already comfortable with the normal ones but you may find them nice.
