### ⭐⭐⭐⭐⭐ Best open ear headphone considering budget & quality.
*by Y***H on 29 September 2025*

Excellent quality. It satisfies my purpose to be environmental aware and also do my task without any problem. Quality of sound is excellent. Only if your purpose is hardcore music then it will not be ideal other than that amazing.

### ⭐⭐⭐⭐⭐ It fits in my ears very firmly
*by M***. on 5 August 2025*

The sound quality and overall quality of the product is awesome

### ⭐⭐⭐⭐ A Decent Open-Ear Option (But with Some Flaws)
*by A***R on 6 August 2025*

In short: Pros: Great fit, good sound for instrumental, very low leakage, excellent awareness of surroundings. Cons: Not good for calls in noisy places, poor Mac compatibility, shady return policy. Detailed review: I wanted open-ear buds mainly for one reason: I really don’t like putting anything inside my ear canal. I’d been waiting a long time for a decent product like this. I had seen bad reviews about the cheap ones from Boat, Noise, and other brands that just slap their logo on generic Chinese products with zero real innovation, so I stayed away from those. Then I came across this JLab pair on Amazon. Honestly, I was skeptical because I’d never heard of the company. But after checking online, I saw they have a decent presence in the US and Europe. I also watched a few YouTube reviews where people said it was good, so I gave it a shot. Now for my honest take: it’s actually pretty solid. The fit is great—snug and secure. No chance of it falling out, even if you’re running or cycling. Sometimes after wearing it for a while, I do feel a little bit of pain on the outer ear, but a quick adjustment fixes it, and then it’s fine. Sound quality is good. I’m not into heavy bass; I mostly listen to instrumental music, and for that, it works really well. Instrument separation is clear, and even at high volumes, there’s no distortion. I was worried about sound leakage since these don’t go inside the ear. But leakage is very minimal—someone would literally have to put their ear right next to yours to catch anything, and even then it would just sound like a faint mumble. So privacy-wise, no complaints. Another plus: even at 100% volume, I can still hear what’s going on around me. So you get good environmental awareness without sacrificing the music experience. For calls: in a quiet place, it works fine. But in noisy environments, the mic picks up a lot, and the other person hears distortion. So not the best for calls outdoors. But I don't take a lot of long calls, so it's not a problem for me. Now the downsides. On my Android phone, it works perfectly—smooth every time. But with my MacBook, the dual-device pairing is a headache. Constant connection issues, which were frustrating. And here’s the worst part: the return/replacement policy. When I ordered, it said “return only.” After I faced issues with the Mac, I thought maybe it was just a faulty piece. When I tried to return it, suddenly the app showed “replacement available.” I went ahead, but when the delivery guy came, he said the system didn’t allow replacement, even though he had the new set with him. Customer service confirmed it—only return, no replacement. Honestly, that felt like a shady tactic by the seller. There should be full transparency about this. I’m keeping it because I badly needed open-ear buds, but JLab (or the seller) really needs to fix their policies. I honestly want more companies like Oppo and Realme to jump into the open-ear market, because there are definitely a lot of people like me who prefer this style.
