A little large to pass for a hearing aid, but overall its a great earbud.
I use the one piece ear bud for work. Headphones aren't actually allowed where I work, but this earbud looks like a hearing aid. Its a little larger than the 4hr versions, but the battery lasts me all day. I have also noticed the bluetooth range is much stronger too. Its a little on the large side to pass for a hearing aid, but this earbud is great and works advertised, I have been thru at least 6 different brands of earbuds now and this one is far and away the best. I have 3 of them now.

Great for work
I'm writing this after my first day of work using this headphone. I bought this because I needed something to listen to videos at work, while still keeping on ear available. Pros: - Fantastic battery. Can handle a 9 hour shift with ease. - Sound quality is pretty decent, no crackling. - The button requires more force to press, which prevents accidental pauses when readjusting - It never fell out of my ear Cons (Small): - Not huge, but on the larger side - At around 7/8 hours in, it started to become uncomfortable. Fortunately you can just switch ears. - On random days, it will "shadow" disconnect every time you pause a video or a song, which can be a hastle. - These earphones are less good at handling earwax that can build up from frequent use, so you need to make sure you clean them out more regularly than other earphones.

excellent value
As I have only one functional ear, these single earbuds are an excellent fit for me. The sound quality is excellent and they stay charged for a long time. The only issue I have is that the cover for the charging port gets in the way when plugging the device in. Minor annoyance for an otherwise fine piece of equipment

Inexpensive way to listen to books
This is probably a niche item--for example, if you listen to books like me, this is perfect. However, if you want to listen to music or talk on the phone, this is less than ideal. I found the sound to be a little tinny--plus it is a one earbud thing--without a proper microphone. I love that it comes in a flesh tone so its not obvious that I'm listening to books... I listen to books on a kindle for pc app, kindle paperwhite (bluetooth capable) and kindle for android... and I got this device to pair with each of them no problem. One button press turns on the earbud, a long button press puts it in pairing mode. It charges via usb to micro usb--there is a small (really small) cable included with the device. I recommend getting a larger cable because otherwise its a bit hard to get older eyes to see and older backs to bend when trying to connect the micro usb male to female port and a longer cable makes things so much better. There is a tiny door at 45 degrees to the earbud part that you can miss if your not looking for it that opens up the micro usb port. One reviewer even said that there's no way to charge the earbud. Trust me, the little door is there, its just a bit stealthed. I actually prefer the usb setup that this earbud has as compared to the charging case setup, as the usb setup eliminates a point of failure (in my last much more expensive earbuds the charging case went bad before the earbud did). Plus, a usb charger helps keep the price down. Some reviewers have stated that it doesn't fit in the ear well. For me it worked fine. I consider myself to have a medium ear canal. While it does come with different ear tips, I can see where some people with smaller ears might (or might not) have trouble. For what you get for the price--this is fantastic--especially if you are listening to books. If on the other hand you are looking for a higher end earbud (2 buds/stereo, good sound quality over phone, wireless charging, water proof, portable charging case), obviously this isn't it and you'll want to pay more. In my opinion for the price of $14.00, its well worth the try--and if it doesn't fit your ear right--well, you bought it on Amazon and can return it. Clever you. :)

Died and wont charge after fewer than 10 uses - no help from manufacturer
I barely used this earbud because it was significantly larger than other similarly priced models. I reached out to the manufacturer to let them know it simply stopped working after such light use and received a reply that does not even make sense given the item is no longer returnable - among other reasons: Feb 25, 2023 1:08 AM "hi. we arevery sorry for it. Please send apply for replacement at your page, Amzaon will charge the after-service." There are plenty of less expensive alternatives to this device that are much smaller and have proven to be much more reliable. I would suggest nobody buy this product - it is low quality and the manufacturer is not making an effort to stand behind their product other than a reply so that Amazon knows they replied vs getting their rating docked for not responding.

Just ok.
I've bought 3 of these over the last year or so. They are decent, but are about what you'd expect for the price. I essentially got them to listen to podcasts during the night as I try to get to sleep or while I am out and about. Sound quality is not great, but it serves the purpose I have for it. Would not recommend to use for listening to music or phone calls. The call back function is more trouble than it's worth. On more than one occasion I have found myself accidently making a call as I tried to turn it off. The buds are rather snug and generally stay in place once you determine which of the plugs is best for you. However, I do notice they tend to become loose and have to be adjusted frequently if I move my mouth to say a few words or eat something. Connects to my device nearly instantaneous, so no complaints there. The main issue I have with it is the battery life. Yes, it lasts around 10 hours.....at first. However, I noticed a significant decline in all three of the units I own after a handful of uses. My first two now get around 4-5 hours on a full charge, while the one I bought merely a week and a half ago has already dropped to around 7 hours. And this is with the volume turned down to its lowest setting. So, do not buy these today and expect to have a full 10 hours of use in a month or so from now. Again, these are about what you'd expect for the price. I paid around $12 for the first two I bought and $15 for the last one. No way would I pay much more than that. They do serve the purpose I have for them, as they provide a source for the low background noise I need to help me get to sleep without bothering my wife. Though they work for me (more or less), I realize they will not meet the needs or standards of most users. If you are looking for an all-in-one bluetooth ear bud with good sound for music and phone calls, I suggest you look elsewhere.

Great battery life and sound quality for podcasts
I have been using these earbuds for several years now, and I love them! They fit comfortably in my small ears and the sound quality is perfect for listening to podcasts and audiobooks as I run errands and work around the house and yard. I prefer to only have one earbud so I can still maintain my situational awareness, so these individual earbuds are perfect for me. If you are an audiophile and/or looking for serious noise cancellation, these probably won't be what you're looking for, but for the sound quality is clear and loud. It has the ability to make and answer calls, however people on the other end of the line sometimes tell me it is difficult to hear, so I don't often use it for talking on the phone. Another thing I appreciate about these earbuds is the price. I lost one at the dog park last month, which was annoying, but I just ordered another one, and I didn't feel as guilty as if I had lost a hundred dollar headphone made by a fruit themed company. I can afford to have two at a time, so I can wear one while the other one charges. Speaking of charging, the battery life on these is excellent! I can literally turn it on at 9 am and don't have to recharge until evening! It does vary depending on usage, but of all the inexpensive individual headphones I have tried over the years, this one has the best battery life. It also comes with a USB charging cable, which I prefer over proprietary charging set ups because it's easy to find a charger if you're somewhere without the charger, or the charger breaks or something. Overall, if you want a single earbud for listening to podcasts, audiobooks, or music, casually, you can't go wrong with these!

Excellent earpiece
Excellent earpiece for listening to music, videos and phone calls. Very durable. I purchased my 1st one in October 2023 and my back up 2nd one in June 2023. Both have been working very well. Recently my 1st earpiece was accidentally left in a shirt pocket and went through both the washing machine and the dryer cycle. It still works, probably better now after getting the ear wax washed out. Lol. I'm impressed. I highly recommend this earpiece if you want a discrete ear bud. The beige color give an appearance of a old style hearing aid. If they make a smaller version with the same quality, I wouldn't hesitate to buy a couple more.
