Review: Works 10 hrs. + great CS - I bought these because I was looking for a long charged earphones for sleep. I'm a back sleeper so, even though they are a little bulky, they stay snug in my ears all night and I don't need to "unplug" when I wake up for pee breaks. I've never been awakened by a loud reminder to recharge (as in my last set). I am a chronic insomniac that relies on a few podcasts to help me sleep. The sound is great and they feel comfortable (although I've replaced the ear tips with a popular foam to help with outside noise). However, I've found that their deep ear eartips (probably silicone) make my ear canals sweat because I wear them so long. That's the only drawback, besides what I'll inform you why I exchanged them, and I've resolved that problem. Last night, however, the right earbud wouldn't work. I looked to be sure there was no obvious breaks, but couldn't find the problem. I contacted desertcart customer service and they offered to replace it free TODAY! I called at about 10 a.m. and they just arrived before I started to write this review. They understood the problem and corrected it IMMEDIATELY! Kudos to desertcart for their prompt customer service! I will update this product in a few weeks, at the latest, to see if problems still occur.
Review: Better than I expected - So to start off, I need to explain a little about my situation. I am a small person. One size smaller in eye glasses and I would have to shop for children's sizes. I have a lot of issues with earbuds due to the fact that so many are too large It has nothing to do with my ear canal (I actually wear medium sized tips most of the time) but because my ears are small enough that the tips can't get fully into my ear canal to begin with. If the tip buts up against the base, I can't wear them at all. I have dragged my feat moving to Bluetooth earbuds for years. All of the ones I tried in the past had major issues. Horrible audio quality, horrible battery lives (having to charge multiple times a day), painful or impossible to fit my small ears. So I was content to stay where I was with wired earbuds. And then I had to replace my phone, and audio jacks are pretty much going the way of the dodo. So I gave in and gave another try at Bluetooth. After some research I decided to try these. Battery life is very important to me. I spend an obscene amount of time commuting 5 days a week. I spend a significant amount out walking and hiking. The last things I want is to have to charge them multiple times a day, thinking about how long until I need to charge them again, thinking about what I plan on doing and whether or not my charge will last long enough. So, my impressions. The fit is good. Not just good, its almost perfect. the stems are long enough that the base of the earbud does not keep me from being able to fully insert the tips. With the medium tips, I get a very good seal which helps to both allow the sound quality to come through completely, but also easily stay in my ears with no pain, discomfort, or flat out falling out all the time. Sound quality is a lot better than I expected from reviews. I'm not talking high end Bose quality, but they are way better than any other Bluetooth earbuds I have tried in the past. Nothing sounds muffled or tinny. Decent at low, mid, and high ranges. I can listen to music as well as audiobooks and not be distracted by issues in sound quality. Battery life. In the approximately month since I've had these, I've never had to charge them more than once a day. They did die on my one evening while on a walk, but otherwise, the battery has managed to last when I needed it. I LIKE the cord. I am an absent minded person. If something isn't attached to my body, I will loose it or forget it. The wire means I can wear it around my neck. The wire means one earbud doesn't go missing to never be found again. The only down side. In a month's time I have already lost one of the tips. Sadly this is a major failing of every earbud out there on the market. I've never not had a set of earbuds without the tips disappearing at one point or another. I actually have a cache of them at home for that occasion. Now these are not the same size as my old earbuds, those tips won't fit. After a little searching, I called the company to see if I could buy new or if they could point me somewhere I could get replacements that would work. Instead they just sent me a replacement set. For anyone who may be in need, I also found that the SpinFit CP155 model earbud tips work perfectly with these earbuds. In fact they fit snugger on the stem (might help with losses) and the mediums actually fit my ears a little better than the stock tips. The only thing I haven't been able to test is its water resistance. I live in Seattle. Rain ins't weather, its just a fact of life. And that rain does not keep me from walks and hikes. I am a little nervous there, but I guess we'll see how it goes come fall and winter.

### ⭐ Worked great, for the 3 months that they worked
*by I***N on March 9, 2019*

I used these at work and while biking, which is usually most of my day. I loved them as a budget bluetooth pair of headphones, would autoconnect to my phone, decent sound quality, good battery life, although definitely "built discount" (not the most bulletproof build design), but then one day the LED indicator turned purple instead or Blue or Red - the day after that happened they stopped connecting to my phone. I tried disconnecting and reconnecting to my phone, wiping my bluetooth app cache on my phone, tried friend's phones, tried factory resetting the headphones themselves, ad nauseum. Nothing is making these headphones work. I thought I bought a 4 year protection plan with them but now that I'm looking at it, it looks as if that was some sort of tack-on from another seller and not actually insurance for this device (Please correct me if I'm wrong).
