Loving these headphones!

Loving these headphones, I didn't realize how much I was missing with my kids old Sony headphones. Kid also said that the bass was amazing on these.

awesome headphones

i have owned these headphones for about two years now, i haven't once thought about replacing these... the sound quality is great wired or not, you can have multiple device (i have my desktop, meta q3s and phone) and it auto switches to whichever is playing audio. i got custom shells as well and they haven't gotten marked up or scratched up and i put them through a lot lol.
my ONLY complaint would be the price BUT they are great headphones so wut?

Best Headphones I've purchased in Years

My sister-in-law ordered these on a whim and she liked them a lot, so I ordered me 1 for my birthday. When we go to their house after our party, I tried hers out and I fell in love with them. It secured me buying them. When I officially received my headphones, I was so stoked. I was able to get them all connected to my phone and the app. I wish I could use them at work but my job requires me to have an available ear to hear calls. I plan on buying the earbuds, but I can't afford them at this moment. But I have recommended these headphones to all my music lovers and especially metal music lovers and they ordered them as soon as they tried mine. Even my coworker bought a pair the next day. Thank You Heavys. Your the best.

Have the headphones and earbuds

I absolutely love both the headphones and the earbuds. They make my Bose products sound so hollow in comparison. I love listening to my playlists through these. Favorite way to listen to music ever.

Superb Sound!

My sister had bought the regular headphones and let me know they were even better than advertised. I might try them next but I had been searching for earbuds. I’ve tried many brands in a huge price range. Nothing was ever that great. I take my sister’s word and decided to see if the earbuds were as good. For me theses earbuds are what I’ve been searching for! The sound is amazing and their app allows you to customize it even further to your listening style. I love the foam ear tips. They do come with the silicone but the foam had me curious. They feel great. They have the buds fitting just right into my ear canal and don’t bring irritation after a longer listening session. I highly recommend checking these buds out if you are looking for a pair that fit every desirable just right.

The headphones speak for themselves but it’s a cool feature to be able to change up the look of your headphones with some of your favorite bands!

Earbuds are awesome, noise cancelling works great, can't hear anything even with no music playing, if your into metal these are a must have, drums are crisp, vocals are clear, listen to songs how they are meant to be heard

Dude...these are sick!

I love everything about these headphones! The sound is perfect and the ear cups comfortably fit over my entire ear. One of my favorite features is Hell Blocker - super awesome!
