absolute best choice i have ever made

“I grabbed the Heavys H1H with the BabyMetal shells on a whim, and as a heavy metal listener these things feel like they were forged for my playlist. The sound quality hit me instantly—crisp detail, huge energy, and that addictive ‘live’ punch that makes riffs feel massive. Comfort is unreal even with glasses; I can wear them for long sessions with zero hot spots. HellBlocker ANC is the strongest noise cancelling I’ve ever used—the only tweak I’d ask for is labeling the EQ sliders so it’s obvious what’s low-end vs mids/highs.”

Heavy's deliver

I've had a number of bass-heavy headphones (Skullcandy Crushers, Nuraphones) as well as some good all-arounders (Sony WH1000xm3, Soundcore Space Q45) and these are my pick over all of them. Having 8 separate drivers does real physical work that can't be virtualized. The bass is punchy, and bass drums have a real "thomp" to them, while keeping other tracks well isolated. This gives such an open soundstage in a pair of cans with ANC. Honestly, it's like the audio version of when your YouTube video switches from 360p to 4k.

Case seems like it was designed by someone who makes guitar cases (very good thing). Cables seem to be of a good material and thickness

Amazing. They do everything as described. The sound is like your sitting in the movies and the hellblocker amplifies it. This is exactly what I was looking for in a look time of listening to metal music

Heavy hit hard.

These head phone truly hit all the right places when listening to your music, everything is very crisp and the bass is just another level. And when you switch in the noise cancelling system you are now at that concert. I’ve used Bose for years but these are special.

Headphones and earbuds

I own both headphones and earbuds! I have tested them against all the brands- no one brings sound like Heavy audio does! I listen to all types of music - not just rock- these are the best headphones on the market!

These shame other big brands!

When i first tried my H1H headphones I was underwhelmed and disappointed. Like "damn, thats it?" They weren't loud at all. Then I found the app and cranked up the equalizer and these backed up and shit all over the beats headphones I had. The best way to describe these are that they isolate every individual sound and present them to you at the same time, they're not overwhelming, just super clear. Ive never heard music like this before. All genres sound great, even podcasts. I found out that if you use the aux cable with an mp3 player or something, the headphones work while they're turned off but if they're on you get a much richer sound. The versatility (wired/wireless, gaming option and the adapter for guitars, i can use these for phone calls, built in controls, etc), quality, clarity and level of thought that went into these is simply incredible. These are a true all in one package. I wish I had something like this when I was a kid. The only thing I would change isn't even with the headphones, its the case - there's no room for the charge and auxiliary cables. Get these, they're worth every dollar!

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?
