Was very impressed with the full mix of bass mid and treble with the 2 tweeters on each ear

Was very impressed with the full mix of bass mid and treble with the 2 tweeters on each ear. And with the heavys app giving you full simple control of the EQ to adjust everything to your specific wants. I get the volume and ranges that i always wanted out of a pair of headphones. And the interchangable shells are sick. Darko, Spite, Suicide Silence and Fear Nation have never sounded so good without a good stereo. Very impressed and i hope your business thrives in the upcoming years!

Absolutely Top Tier

Head phones are a huge part of my life from work, the gym, household chores, to just everyday life. And I’ve used them all, I prefer quality over quantity so you can imagine the money I have spent for quality sound. I can’t begin to describe how fantastic these headphones are, from opening the box to the first pairing this experience has been beyond expectation. The sound quality for every song no matter the genre. Then the app that allows you to customize your EQ is next level no matter what your brain needs to hear it is possible with these! Thank You Heavy’s for crafting such a fantastic product 100/10. I will purchase this product again.

Delivers what's promised

I've had better noise cancelling and better sound overall. But I've never had better sound specifically for metal music! The headphones are very confortable. I love that I can customize mt Heavy's with custom shells. The ones I want are out of stock so I haven't yet. But I will sooner or later. I'll probably order the in ear Heavy's in the future as well.

Love these shells! Great way to customize my Heavy’s and showing one of my favorite bands some love!

Another home run! The headphones are EPIC!! The ear buds are just as good, comfortable and both are the best way to listen to Metal hands down!! Been a customer from the start and will continue to be.

Superior sound quality. I can just get lost in the music doing daily tasks. If they were sweatproof they'd be my gym pair for sure. Excelent build quality, and can be used for more than just heavy metal especially with the Heavys EQ adjustment. Highly recommended!

Heavys H1H & H1E

Treated myself at Christmas with both the H1E earbuds & H1H headphones. AMAZING!! Blown away but just how good both are. The build quality, sound , comfort is nothing like I’ve had before. The Heavys team & Axel Grell have clearly put a lot of thought and time to create something very special to take your heavy metal listening experience to the next level. Highly recommended, thank you Heavys 🤘🏻🤘🏻

I’m Heavier with H1H Headphones

These are sick, I also downloaded the app to customize them, and make them sicker. I love these headphones, and the interchangeable shells. Thanks!

Best headphones ever!

I got this pair because another pair of different headphones broke and holy! I’ve never been more happy with headphones. This is the best sound quality I’ve ever heard and the battery life is incredible. I also sleep with my earbuds in and they didn’t fall out once. 10/10, would recommend

Definitely worth it!

Heavys are exactly what I expected, a definite upgrade from my previous headphones. Love the hell blocker feature and the option of head padding for smaller heads. Sound quality is amazing and I love the cable option so I can plug these into my guitar’s amp! My doggo loves them too 😋

HEAVY!!! Quality buds.

Really happy with my buds. Look and feel quality, like the App and easy set up.
Sounds fantastic. Clear, deep, heavy! Love the sound. Great work. Can’t wait for some more band shells to customise them!

Built for Metal Lovers Who Want Power and Clarity

I originally bought a pair of Heavy’s headphones for my husband as a Christmas gift, and he loved them so much he immediately told me I needed my own pair. After using them myself, I completely get the hype.

These headphones are clearly made for metal. The sound is incredible—heavy and powerful, but still clean and balanced. The instruments really stand out without overpowering the vocals. Everything sounds clear, crisp, and exactly how metal should feel.

One of my favorite features is Hellblocker mode. My gym blasts pop and rap music nonstop, and this feature does an amazing job blocking it out so I can fully focus on my workout while listening to music that actually pumps me up. No distractions, just heavy riffs and motivation.

If you love metal and want headphones that deliver power without sacrificing clarity, these are absolutely worth it.
