Upgraded Quad Drivers Bluetooth 5.0 Headphones, HiFi Sound Wireless Earbuds, 16 Hours Playtime, IPX7 Waterproof, Noise Isolating, Magnetic Sport Earphones with Mic for Running, Workout, Gym

EDIT: I have now bought this product twice. The first time was on Jan 25, 2020. The most recent time was October 21, 2020. It is now June 23, 2021. Both times, the headphones gave out the same way: The left earbud just decides to stop working. Or at least, stops working as hard, which creates a disorienting feeling - not unusable, just uncomfortable.But man. In its price range, this thing has crazy good endurance. I run it basically all day every day. I rarely need to "rest" from it, as it fits my ears very well. And as a computer scientist and an online tutor, I am basically always at my desk. Always listening to something, up until I fall asleep. And it just keeps up with me for all but the most insomniac of days.I think I really love these earbuds - for the price. I might buy them a third time, if none of these other earbud orders actually produce a good set that I like.---Original Review Below---So, major complaint: There's around a 0.25 to 0.5 second delay between sound being sent the headphones playing the sounds. And this includes when the sounds stop, where it just blasts static for a bit. This can make watching video with a person speaking be actually nauseating.But this is the first wireless headset I've ever had so maybe that's inherent to literally all wireless headsets, so it's unfair to criticism it for being what it is. So, I'm only taking 1 star off for such a failing.But on the same point about this being my first wireless headset, it's incredibly liberating to not be tied to anything I listen to, and still have the privacy of earbuds. I left my phone to charge on a dinky public charger, and didn't need to finagle it at all. Not to mention I can actually get up from the computer and do stuff without stopping youtube, or risking missing a student wanting to come in for an online session. The freedom of wireless is fantastic.To move on to things probably less innately tied to "just being wireless," the sound quality is perfectly acceptable. When it's not blasting static, which happens only a little bit after it stops getting signals to produce sounds.It is incredibly light and portable. Having it around your neck all day is not an impairment at all. Then again, I also just wear a lanyard with my keys and ID around my neck, because my pockets are full of my other stuff. So it's probably less alien to me than others.And the battery. My god. I've had it going from late this morning, to about 10 PM right now, and when I last checked it by linking it to my phone, it was at 90% charge. It's probably at 80% right now. But damn. That's impressive.The "noise isolation" that it boasts? Eh....No. No more than sticking any other earbud in your ears would. Although it does a disproportionate "isolation" from high pitched noise over low, which makes use in the car absolutely terrifying.There's one final issue that's probably uniquely mine, so, take this or leave it. After I've had the buds in my ears, I started feeling a dull pain in the front of my neck, like I had caught my shirt on my jacket, and it was choking me. Check it, and nope, nothing even touching it, but the strange feeling remained. It was only after removing the set from my body did the feeling start to fade.Very strange. Incredibly so. I mean, I've still got a metal rod in my neck and the scar from the surgery that happened about a year ago in the same spot as the feeling. I've just got absolutely no idea how these earbuds could even be interacting with a scar. Maybe it's just in my mind. Maybe it's the fact that they wrap around most of the neck, and just lie there, and my mind's just filling in the gap in sensation? Dunno.

Originally I had poor use of the model 6 after a few weeks. I wrote a review of the issues and Customer Service contacted me and sent me 2 updated models to check out. The 6 model didn't work out for me. The 9 model is great and the 10 model delivers everything I need. Below is the original review of the 6, an update after I used the 9 for a month and a second update after using the 10 after a month.ORIGINAL REVIEW ON THE 6 MODEL. after 3 weeks started getting 1) static on 1 earbud; 2) when plugged in didn't fully charge or at all on occasions even when over night and light was showing it charging, 3) unpairs from phone often, and has to repair before continuing 4) never got more than 8 hrs battery life when listening music. conclusion: not buying this again UPDATE Model 9 After the previous review I was contacted by Miss Elsa - out of the blue. she sent me an updated model from a 6 to a 9 for my review as well as a model 10. She is the example of great customer service as well as standing behind their product! After using the model 9 I found no issues - just great sound, good connections every time, and feels good in the ear.UPDATE 11/29/2020 ON 10 MODEL I have now used the new 10 earbuds for a month and I'm extremely satisfied with the product. Battery lasts a very long time as claimed, clear music/calls and callers have no problems hearing my side of conversation, Connects easily and securely with phone every time. I wear these mainly (70% of the time) in a very noisy environment under either 23 or 30 dbh headphones, no issues with rubbing or ill fitting with headphones. Miss Elsa at customer service is wonderful to work with, stands behind their product to confirm their company is providing a worthy product as well as making sure the consumer is happy. I HAVE OWNED SEVERAL DIFFERENT BRANDS OF EARBUDS - I PLAN FOR LINKLIKE TO BE MY GO TO FOR ALL FUTURE PURCHASES!!!!!
