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 Amazon 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.

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
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.

I am a happy camper, Way more than I was expecting.
The Product quality is good and the sound quality is far better than I expected , these work well with my Hibby 3 and my pc , phone connection was quick and easy with the app allowing for tweaks to controls and equaliser settings. I would recommend these ear pods . I am a happy camper.

Disappointed
I purchased the Soundcore C40i as I am a current user of Soundcore C30i and trusted the brand. However, I'm totally disappointed. The sound quality and battery backup are very disappointing.

DOES THE JOB NICELY!
I’ve been buying soundcore for years, I have a few of the ear buds, obviously these will not be like buds in your ears, these are easy to wear and very sturdy but easy to remove. I’ve only had them a few weeks, but so far so good. The sound is pretty good, and you still get a good experience when out and about. Which is the main reason for these so I can still be aware of my surroundings and people around me, they’re a dark grey Matt colour, they do look cool. Case is slim and easy to use.

Not impressed by the sound quality
I returned these earbuds as I was not impressed by the sound quality at all. There was also a lot of sound leakage, more than I expected for open ear buds.

Disposing ted with fit!
Like many others was excited to recieve these so I charged them immediately and used the next day! Positives they are comfortable to wear but depending on position in ear you can’t get a good sound. Discounted to say I’m returning them. Really wanted these to work for as I struggle with the in earbuds.
