Absolutely Amazing!!!!

I really don’t think there’s a better headphone out there, they sound so good, and they’re so comfortable, and for a metal head like myself, that means everything, will definitely be buying more shells in the near future

After two years, new review

Have had my heavys for just over two years, still the best audio and comfort I've ever had from headphones.
The customer service has always been absolutely fantastic with different orders of shells and replacement pads Ive had.
Only after about a year and a half did the ANC stop working as well as they used to (water damage I believe)
Overall absolute 10/10 I cant wait for my heavys earbuds to arrive when they officially release. 🔥🤘🤘 Horns up

Very happy !

I bought this to be able to play piano at night when I can't sleep. I bought a good piano with a good sound and a good headphone (Heavys of course) so I wanted a good cable to enjoy them and I'm NOT disappointed !!

Really enjoy them

Really enjoy them. My ears have cauliflower and the extra space means they don’t start hurting like in other over the ear headphones.

Something else I like is being connected to multiple devices at the same time. I can be listening to music from my computer and when my phone rings the audio comes right through to the headphones without needing to switch them and mess about Bluetooth settings. Really really recommend these.

Heavys H1H Headphones

Revolutionary

These headphones have actually made me cry they’re that good. I’ve never heard my music so clearly before and it helps amazingly with sensory issues. 100% a worthwhile purchase. The quality is amazing and the customisable shells make them so so unique. i’m absolutely obsessed with these headphones

Quality Audiophile Headset

Fantastic sound both for music and gaming. Very well-made from quality, lightweight materials. Removable microphone is easy-to-use. Simply put, I love them. Would recommend them to any decerning audiophile.

BRUTALLY HONEST REVIEW!!! 🫩

I’ve been using these headphones for 5 months now and I can say they’re the best headphones I’ve ever owned. I’ve used beats, skull candy, Bose, and Sony but overall these have been my favorite. I love how bold they look and they sound like you just stepped into a studio booth. I will say however the price is a bit high for the headphones and for accessories. Your spending $300 already on the headphones, it would be nice if the shells were priced at like 25 and the mic like 35 but wtv. I’m still waiting to buy mods because It feels unreasonable to spend almost 400$ to customize my head phones. If your an average music lister I’d say your better off buying skull candy’s or a pair of Bose. But if you’re really passionate about music then it’s definitely worth it. Even connected to the amp it makes me have more confidence because of how crisp and smooth the audio sounds. They also work great in the Gym, blocks out almost all the noise. Depending on what I’m listening to I can hear background noises but very faintly. I also wish they had a tighter grip on my head, during some exercises they tend to fall off. I also don’t like how the material of the headphones react with sweat no stains or anything but it just gets really wet. Every single person I’ve let try these headphones have been blown away. Again whenever the price comes around people immediately freak out but when you take into consideration that these headphones are a product of someone’s life work, it becomes slightly reasonable.

I love these bwadphones! They are hands down the best headphones I’ve ever had. I listen to a lot of bass heavy edm and with any other headphones theres always a lot of distortion and you miss so much of the song but with these it sounds like you’re there at a live show. They stay charged for a really long time. The noise cancelling is really good (it blocks out the sounds of the nyc subway/bus). The padding on the head band and ear cups is comfortable. My only complaint is they are physically heavy but thats to be expected with all the stuff in there that makes them so great! Oh and the mic is way better than my airpods or sonys for making calls. People never could hear me with those headphones and they hear me great with these.

BuyThem or You're Missing Out!

if you live in a place where you can't turn up your music on outside but love your music loud, these are for you. just using my Heavy's is just as good. my phone supports aptX codec, and the Heavy's eq app makes an outstanding pair for music. fact is it is as good or better then my 5000 dollar gaming computer. which I can walk into my office, I can either Bluetooth or with the included headphone/mic wiring can expand up to 32 but 96000 bitrate for very fine sound. I find though after putting the aptX codec on my PC that it only requires 16 but 48000 to match very well. I hear thing that only very fine audio can reproduce. I use Amazon unlimited and I just set to standard music. the sound is amazing. highly.reccomend

HEAVYYYS!! F#ck yeah!

I F#ck!n’ LOVE THEEEEM!!!
Best headphones I’ve ever gotten for myself.
I love the clarity, the right amount of bass and the mids sound clear, not muffled like other headphones I’ve tried in the past.
I DEFINITELY recommend Heavys to any metalhead out there.
The Dark Funeral shells just give it that sick look. Love it when ordinary people just stare at the shells hahaha

Blown Away! Most Metal Experience From Home!

A friend told me these H1H Headphones existed. Right away I did my own research, took some time to read through reviews and materials and add a pair to my cart. Being a dad of two daughters, I got side tracked and left them in my cart and a day later, I got a text from Heavys customer service representative Sarah. She was able to help me and guide me to my purchase and explain some additional things. Not only was the process smooth but Sarah added a personal touch to the experience like being at a festival with a friend. I am blown away at how metal this whole experience has been. The sound is insane and so is the company!

These headphones are dope!!!! Absolutely skull bashing! 🤘

Despite waiting over 3 weeks for mine to show up, I’m super thrilled with these headphones. I’ve been hesitant to buy a set of over the ear headphones because none can replicate the sound like these Heavys H1H.
I just got mine today & im so excited.

Great headphones!

Great headphones! You can almost feel the bass like a live concert. You can even hear the bass in metallica's and justice for all ;). The overall quality is excellent.

Best headphones I have ever owned

Pass on the cheaply made 'Get Beats' and buy yourself a pair of Heavys H1H Headphones. These headphones are amazing.
