Linklike 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.

Update 2 (09/28): I gave it 5 star now after using it for sometime. Sound quality is great. I had issue with the fitting and so I ordered XL size buds and it fits well now. The reason I increased 1 more star is for the great customer care. They reached out right away after my first review and in fact ordered larger buds to help in the fitting. Thanks! Those buds do work well but I prefer the one I bought. Anyway I love when product team cares about customer and try to resolve issue. That tells you the product matters to them and the customer satisfaction Thanks! Update 1: I have used it for two days, sound quality is good comparing to well branded products! My review is entirely based on the fact that I wear them when I ride my motorcycle. So to me quality of a earphones depends on: sound, ambient noise plus loud bike sound, fit, battery life, easy carry, and connectivity. This one checks all of them so far except the fit. For normal use it is a ok fit, but it does not fit snugged which I need as when I change the tracks while riding with one hand and changing with left hand, the ok fit will/may pop out. So I have hard times changing tracks. I am looking for bigger buds for this as I have liked the others aspects to keep them for the time being. If anyone or the manufacturer can recommend better buds or larger buds or how to fit for my purpose, that will be great! That is the only reason I gave it 4 stars. Also I need to check the battery life and will update then.

NEGATIVES: (* NOTE: May not be bad enough to be dealbreakers, though Product Development at Linklike might want to address ALL of these issues for future versions. I remember reading some of these criticisms in other reviews, so I want to mention them again for extra emphasis, since they’re things that can be improved upon.) - Sound for keyboard too sharp and punctuated (like a POPPING sound), and is too loud (it irritates my ears), and should ideally be softer/muted and lower-pitched (Apple does a good job with their sound). Makes me wince a bit, the way one might feel when anticipating a balloon being popped by a needle. - Not necessary for low-battery warning to go off CONTINUOUSLY for 20 min., until battery dies. As other customers have noted, ONCE is enough...let us enjoy the last minutes in peace. - Noise isolation is nearly non-existent with these, for those who are accustomed to earbuds being able to block out ambient sounds, even when no sound is passing through headphones. With music playing at a moderate volume, I can still hear people speaking clearly. Hopefully, this isn’t a necessary trade-off to having a lightweight product. I wouldn’t mind a little extra weight, if these could block out more noise. - This might be a semi-dealbreaker because it could become really annoying after a short while, but the AUDIO IS NEVER SYNCED TO THE VIDEO. I’ve tried to go back 10 seconds in the video to reset/recalibrate it, but it never remedies the problem. (* UPDATE: It might be the YouTube app that’s the issue. If I watch the same videos in a browser, the audio and video are synced perfectly.) - Volume doesn’t go down low enough before muting completely, for those who might want to use headphones to listen to something to fall asleep to. It’s about 40% too loud for that purpose. - When power is turned back on, volume goes back up pretty high...a bit of a shock to your system, since you might not be expecting it. I’m guessing that the designers at Linklike must like everything to be extra LOUD, almost all of the time. POSITIVES: - Both earbuds and neckband are SO comfortable and lightweight that I forget I’m using them, even as I’m watching/listening to media. It just feels like I’m a bionic being with built-in headphones. - Sound is balanced and clear. I don’t like intensely bass-heavy music like dubstep, but still like to hear some low-end for that full sonic range. - LONG battery life. Won’t need to charge during the day. - Easy pairing. - Long usage range. I forgot that I had them in my ears, and walked to the garage to take care of my laundry. My TREBLAB J1 pair would break up at that distance, but the Fly 9 reception remained solid and clear. FREEDOM! UPDATE: June 29, 2020 (Mon.) — It’s been about 8 months, and yesterday the POWER BUTTON (center) stopped working. The volume buttons (top & bottom) are fine, but now I’m not able to turn the headphones on or off. I will contact the company and see if I can get a replacement pair. I take care of all my things, and I don’t think the middle button has been used very often, but at least now the company knows where the vulnerabilities are, and how they can improve their product for the future. Will follow up with outcome. UPDATE: July 4, 2020 (Sat.) — As with the experience of others, Elsa in customer service was eager to help resolve the issue as painlessly as possible—she inspires trust and comfort in knowing that you WILL be taken care of. I greatly appreciate Linklike’s ethos of INTEGRITY. They want to do right by the customer, and I plan on being a repeat one, both for their quality product line and excellent customer care. I asked for a replacement of the Fly 9, and I just happened to mention in my message that my next purchase would be a Fly 10, which is their most recent model of the same headphones. Elsa upgraded me to a replacement pair of the Fly 10, which has a 24 hr run time (8 hrs more than Fly 9), so for others like me who wear their Bluetooth headphones like an extension of their body, unless you plan on being awake for more than an entire day STRAIGHT, you will always have enough charge on your headphones. And charge time is pretty much the same as with the Fly 9 (3 hrs). Thank you, Elsa & everyone at Linklike! I’m so happy Amazon connected us! Great value for the money. I highly recommend your product line to audiophiles on a budget...or even if they COULD spend more. Very happy with my Linklike experience. :)
