The best headphones I've ever owned

The sound is absolutely amazing, and when I'm working and have "Hell Blocker" on, nothing disturbs me.

Very very pleased with this product

Best headphones ever!

Bought these for my wife and I, fell in love as soon as I turned them on. The sound quality is amazing, crystal clear, crisp and clean. The shells are just the cherry in top. Great quality, easy to change

Second to none!

These incredible headphones are a must have for anyone who loves listening to music!

Love the sound versatility

I really enjoy the versatility of sound these headphones provide. Solidly built, the EQ app is a good addition. I completely missed a train announcement due to these beauties, no idea what was going on. Sound remains unaffected by a bumpy bus road, a problem I had with Bose.

The Opeth shells are beautiful too.

UNREAL!!!

I was unsure about these headphones at first, mainly just because of the cost., but I had a friend reach out to me through social media and said they were worth it. And he was correct. These headphones are absolutely amazing. The sound quality is just unbelievable. I’ve tried a few different genres: and they all sound great great, but when you play metal through them, it’s obvious that they were designed for metal music. I notice a night and day difference when I switch from these to pole air pods. (I switch because I don’t wear heavy’s in the sauna so I take my AirPods instead)-and it’s a significant downgrade. The ONLY small issue I have with them is I don’t think they have true noise cancelling technology in them. BUT, we metal heads don’t listen to music quietly, so when you’re at the gym blasting The Bkack Dahlia Murder or Cattle Decapitation, the world around you ceases to exist.

Great Product

I am super happy with this purchase. The sound is clearer and loud enough to even discover little perks (a lost riff or drum here and there) within the music I have been listening for decades that I didn't noticed before with other headphones.

OMFG!!!!!

This is the way music is supposed to be listened to! I have gone through at least a dozen different brands of headphones both cheap and expensive, but these take the cake! I have already told everyone I know about them!

Great headphones

I think these are great. I compared them to Sony wh-1000xm5, Bowers & Wilkins PX8 and Apple AirPods Max and I like the sound of the Heavys the best.

It’s so much more space in the sound. The sound space is much more full compared to the other ones I tested. I love that I can hear both the cymbals and the base drum clearly in my metal music. I even hear new sounds in my favourite music now. I think the balance between the base and treble is great.

For reference, I don’t like the sound of the Apple AirPods Max because my ears hurt because of the treble in those.

The Sony wh-1000xm5 have a better noise cancelling sure but the Heavy active and passive noise cancelling work satisfactory. When I have music and the hellblocker on, I can't really hear my surroundings.
Also for me, the most important thing is the sound quality and the Heavys delivers on that.

I actually like that the Heavys have buttons instead of touch. I like the more robust feel of that. I think all the touch functions on other headphones gets messy and unclear most of the time.
