JLab Audio Epic2 Bluetooth 4.0

I've owned several pairs of workout headphones and theyve all been good. Had a couple pair of isport monster headphones, bose sport headphones, jvc, and power beats 2.0. I ran in them in temperatures from 20°F - 100+°F and also in the gym for light and intense workouts. Some of those got uncomfortable around the hour and half Mark and just painfull at around 2 hour mark and would often times bruise the inside of my ear and I would have to shove then back in or readjust them every 30min or so, but they did the job so they were OK. I've worked out 4 times in these so far, ran 3 miles 4 times, and did a long run (15ish miles) and these have not just been good but have set the standard for exceptionally extraordinary headphones for me. Starting with the sound, they leave little wanting, strong for full range of sound, the bass is a little heavy but that is good for a pair of workout headphones, the bass keeps you going. Mids are a little off but not by much. For comfort, it's like you're not wearing any headphones at all. If you take the time to fit the headphones properly it'll be as if you're not wearing headphones at all, they are so light you can't feel them and fit so perfectly there's no pressure put on any part of you're ear. I at least expected them to hurt a little after my long run but never once did they hurt. As for movability and durability, i can turn my head in any direction without feeling the cord pull, have one earbud pop out, or have an earbud become unadjusted. A problem I had with the other headphone was when I ran in the heat the plastics on them would become squishy and eventually after normally around 4 months any type of pastic insulation/material or glue that held the headphones together would fall off(power beats, im looking at you). The real feel temperature of my long run was 106°F in the beginning and 94°F when I ended with about 70% humidity the entire time, not once did the material of these headphones feel cheap or like it was going to fall apart and they stayed in place the entire time, only time I had to readjust was when I doused myself with water. Connecting to bluetooth was as easy as can be, and the connection stays, never once have I had it skip or lose connection while I was relativly near it. I can put my phone down in the gym and walk a good ways away before it starts to loose connection. One thing that a lot of people don't initially think of is how well they fit while wearing sunglasses. A lot of headphone's with an ear clip make it uncomfortable to wear sunglasses with them and from my experience an ear clip is the only way to make sure the headphones don't fall out. These are great to wear with sunglasses, as long as you fit them properly to your ear they don't get in the way of sunglasses. The cable management system is great as well. Keep all the wires in place and out of your way. Somthing else to keep in mind is that most headphones are water resistant and sweat resistant, not proof. Part of what made my power beats 2.0 and isports go out was that my sweat would eat away at the material slowly. Even with me cleaning them after every workout the combination of heat and sweat eventually took its toll and put them in my bone yard of headphones. These headphones are water/sweat PROOF (blood and tears proof is also advertised, but i haven't had a chance to test that out yet). I can pour water on me with zero worries, sweat as much as I can, instead of taking time to clean them with as little liquid as possible I can just run them under water. I have not swam in them yet but plan to soon. If you're looking for a pair of headphones that sound better than any other workout headphones you've ever had, fit better, move with you better, made better, are strong enough to handle you're most intense workouts, and look good then you can stop looking because these are it. Those are all the pros, so the cons. The cover for the USB port feels cheap. Like it'll break if I'm not super careful when pulling it off. The cord that connects the earbuds is not very thick which makes me worried it'll break. And that's it really. Honestly I've never had a better pair of workout headphones.
