Wireless Bluetooth Headphones Waterproof TWS Truly Wireless Stereo Bluetooth Earbuds Noise Cancelling In Ear Headphones with Microphone and Charging Case for iPhone Samsung iPad and Smartphones -Black

Overall works great the instructions stent very good however.. Basically there are two eat buds.. Don't pair both to your phone otherwise it will be a mess.. Pair the right one by turning on holding button until blue / red light alternate... The pair with phone as S2 .. Then turn in the left one just until it's on.. Both will blink red to blue linking with each other... That's it... Always turn on the right one first then the left... I've found that otherwise the right one isn't consistent connecting with the left one...

Well I have mixed results. First let me say that I use it to listen to audiobooks, not music so sound quality is not as important to me. That being said, I thought the sound quality was very good.I love the design and functionality of this device. I use 1 ear bud to listen to my book while charging the other. This allows me to use them continuously. The whole device fits easily in my front pants pocket.The battery life is just OK. About 2 hours on a fully charged earbud. But they are fully charged in about an hour. So it still works well for me.The bad news is that after less than a month, the right earbud suddenly quit linking to my phone or the other earbud. The left ear bud sometimes cuts out sporadically. I did find that keeping my phone more than 6 feet from the earbud tended to stop the cutting out.I'm returning these earbuds since it's been less than 30 days. But I'm ordering the same device to replace it. I'm hoping the new ones last longer.I had a pair of Jam Ultras before this pair and one of the earbuds didn't last 24 hours before it quit linking to my phone. So, I don't think paying more necessarily means better quality.

Good starter set for the price. Battery life is so so.. Intermittent disconnects from time to time but the device seems to recover. Most people will think pairing is a pain in the butt.IT people will have zero issue but don'y recommend for older people, you will just get frustrated. Fit is good. Weight is good. The base tones are non-existent, but that is true for all devices in this price range. I use for rail sytem to work in Atlanta and conference calls. # hours max for continuous use. Note: using only one bud works great fro conference calls.

Ended up throwing these earbuds away today. All of a sudden, only one side or the other (right/left) would play. No amount of factory resetting, messing with my iPhone settings or other fixes would make both buds play at the same time even though in my Bluetooth settings, both S2 buds show 'connected'. This all happened without any warning. They were working fine this morning. I left and went to a meeting and came back and only the left one was working. I searched on Google in vain to find a fix, and was barely able to find any product information about BierTek as a company. Lesson learned....cheaper isn't always better, especially in electronics.I think I'll stick to my wired earphones until I find a better, more reliable wireless brand.

Have used in rain and washing cars and they still work so waterproof A+ I use 1 at a time because that way can have them on without break for charging. Mic seems to work very good sometimes you do need to speak up little. Sound quality it good. For price they are great.

They were good for the first 2 days that I had them then they crapped out. I was only getting sound from my music one side, WHO NEEDS THAT, so I tried to fix it by changing the profiles in the bluetooth settings. But ive had no luck. I dont want to return these yet but for $40 why did this happen? I need help. other than that, they're great its just I would very much prefer listening to music on both sides.

Sound cuts out about one second every 2-3 minutes, and they struggle to stay in ears during any movement or activity.Charging is fairly quick and convenient. They nest securely in the charger as well.They work in the strictest sense, but mediocrity is what one can expect for the price.

I like these headphones, but the only thing that bothers me is, it doesn't synchronize easily with my iPhone X. The sound quality is impressive, it sounds excellent, the bass is perfect, and it’s waterproof, I tried to take a shower with it, but when The headphones touch the water, they don't stay on ears anymore, they fell, the water makes then smooth. I would like it to have proper synchronization and more battery life because it has like 3 hours and charging them take a little while too. Besides those, they are enjoyable.
