Good for sleeping with podcasts
I just got these and tried them out. I needed something comfy for going to sleep with a podcast and sleeping on my side. They worked pretty well. I wanted something small, comfy and wireless, but with long enough battery life to get me through the whole night. I often wake up and so when that happens, I need something to lull me back to sleep. The product says the battery life is only 6 hours,.but it had to have been over 8 hours when it finally gave up. Also, when the battery dies, it doesn't beep annoyingly and/or announce low battery. It just makes a soft, low toned sort of beep. I just happened to be about awake when it happened, but I think if it beeped while I was asleep, it wouldn't wake me up. The sound quality is a bit eh, I can't recommend these for music, I already have some better ones for that, they're just too bulky to wear in bed and side sleep. But since I only listen to podcasts to get to sleep, these are working out great so far.

Poor sound quality and uncomfortable but relatively discreet.
The ear buds are relatively discreet, a lot of people assume they are hearing aids due to their more medical and not exactly sleek design. They work well enough and their range isn't half bad. They charge quickly in the dock which is convenient. I personally use one at a time due to my work environment. When one is dead the other is usually back up to 100%. They could use the inner ear, plug style rubber ends. They don't exactly fit the ears wells. A better sealing fit would make them far more comfortable and increase the sound quality and comfort. I have relatively small ears so these do not fit well or comfortably in my ear at all. But they do work and I can hear them pretty good though they lack depth in sound quality. If I push them tighter to my ear hole to sort of seal the gap the sound quality improves greatly. So they have promise but could use a slight redesign. For the price, they get the job done.

discreet excellent connection
Bought these to send music to both myself and my wife at the same time without having an obvious earbud in our ears. Pros: they connect easily to your phones Bluetooth and the hold a connection even when the buds are separated by 2 to 5 feet. Cons: they are not very loud so noise cancellation is nonexistent. Not sure if I have weird ear canals, but they are extremely difficult to get out of your ear because they are small.

TERRIBLE PRODUCT
The ear bud hurts my ear canal if I leave it in for too long. The battery is okay but I’ve had better products. There is absolutely no noise cancellation feature. The ear bud continually disconnects from iPhone for some reason. If I could I would return this piece of garbage and get my money back. BEWARE DO NOT BUY.

Fit and charging
I have been using this for about 3 weeks now. Overall these earbuds sound quality is very good. Only a couple of issues that I see. They are very comfortable and fit pretty well. I you use them for sleep, you do need the ear wings on as they will fall out. Putting the ear wings on is a pain as they fit very tight. Secondly you have to constantly remove and put back the ear wings as the buds will charge with the ear wings on.

Just what I was looking for!
I work in retail and we all know that sometimes management can have some strict rules. I also have anxiety and like to listen to high vibrational music to keep me at ease but we are not allowed to have airpods in on the floor. These will be perfect for a few minutes of positive vibes! I don’t expect them to last forever but the longer they do that’s even better! For the price they are a 5 star if they give me a few months I will be more than satisfied! They fit in my ears perfectly (I was a bit concerned about that because I have small ears and my airpods 3rd generation fall out often) The sound is great for a work environment. Actually better then expected. And they sync simultaneously with only one bluetooth connection! (Soundcore uses two connections and you have to link them separately) The only down side for me is they don’t have a left or right side indicator (not sure if its even needed) they fit somewhat the same in both ears so I really couldn’t tell a difference. The battery life says 4/5 hrs…im not sure if that’s going to be an issue or not because I really don’t plan on keeping them in for that many hours at a time. Thats it. Thats the review!

Uncomfortable and inconvenient
My goal was to use these at work without being obvious. These were great for that! What wasn't great: the tip can be sharp, actually cut my ears while inserting. The silicone covers help with that, but you can't charge with the silicone on and I had trouble getting them on and off. The charger has a great design, swivel lid with a magnetic closure-but drop it and the lid breaks off. I was able to hot glue the swivel axel to the lid to make it work but it only lasted a few days at a time. I have 2 sets, one gifted to me at Christmas and the other purchased about 3 weeks after Christmas. Around Feb 21st, I was wearing them when one slipped out of my ear and it fell in the sink before I could catch it. Wiped it off and put it back in my ear where it stopped working and began overheating. The next day, I was using my 2nd pair at work and without a drop or possibly reacting to water contact, one bud stopped working and also began to get warm. I half heartedly attempted to pair the two good buds to create one working set but failed. Both were past the 30 warranty which really sucks, I was willing to endure them being uncomfortable because they were discrete and had great battery life.

These are my go to earbuds
I listen to Audible quite a bit. It's great while you're gardening, working, picking up dog poop, cleaning, shopping and so on. The only way I can listen to audible while doing all of these things is with discrete earbuds. I don't want something sticking out of my head or flashing constantly and I want something that can last for at least 6 hours, hook up automatically, be comfortable, not fall out and just be there without being a nusiance in anyway. These earbuds fit that bill. I even use them while I'm sleeping because I need to sleep with noise, but my husband doesn't. They definitely go in my ear that's not on the pillow, but they are comfortable enough that I just enjoy the sound they make without worrying about them. I love that I can charge them on the go.
