Got these for Christmas, my direct comparison is to a set of B&W PX5's (mine) and PX7's (my middle son's), as we have both here. I will also being comparing them to my eldest son's Sony units, which, I must say, sound like hot garbage. I did some back-to-back listening with him and he was rather depressed over how his Sony units sounded after that.

I read a number of reviews before getting them, and have read a few after. Most reviews are good, some individual ones are not. I'll share my experiences here.

They are "designed for heavy music" hence the name, though I find they do just fine on anything. They are like listening to a large set of Paradigm towers, to do a speaker comparison.

These have 8 drivers, which, unlike the electrostatic Sony units, means they have proper tweeters:

This is readily apparent in even the most basic listening, as the highs are strong and clear, while the Sony units are muddy. The B&W's both do well here, I am not sure as to their driver arrangements, but it's B&W, so quality is to be expected IMHO.

Connectivity is pretty diverse:
- Bluetooth
- 3.5mm analog cable
- USB-C with built-in DAC

Down to the review.

These are not "fancy". They have no wear sensors; they lack any active haptics, so they don't pause when you lift one off your ear for example, which my PX5's do. They seem well made however, and, while not lightweights, aren't annoyingly heavy on the head (har har).

I first used them paired to bluetooth on my iPhone and was not blown away. The highs were very present but didn't sound great; sort of sounded like listening to a lower bitrate track. I tried a pile of different artists and songs, didn't make a difference.

I installed the app, which notified me that there was a firmware update, which I performed. This had zero impact on the Bluetooth audio quality.

I skipped the 3.5mm cable with the logic that analog wasn't where I was going to hear them shine, if they were in fact going to.

Enter the built-in DAC.

With them off, I plugged them into USB on my million year old Mac Pro (had to use a USB-C to USB-A adapter cable) and they were detected as a digital audio device. Selected the same tracks in Apple Music (formerly iTunes) and wow, what a difference! The built-in DAC is fantastic. The highs are crystal clear, the soundstage is broad and dynamic, and the lows are strong, but not overwhelming; they don't come across as bass boosted, just seeming to properly do the lows justice.

The difference between the DAC and bluetooth was so pronounced I haven't used them on Bluetooth since, just leaving them plugged into my computer. This means I'm using none of the active features of the units, such as noise cancelling, as that's all disabled with them off and the DAC is run in straight-through mode. You can run them in active mode on the DAC, but they do a very good job of drowning out your surroundings without the active noise cancelling, so I've had no reason to use them that way.

The iPhone management app for them is finicky. It sometimes doesn't see them and you have to forget the headphones and reconnect them for them to be detected. I've never had that issue with the B&W's, which always connect the first time.

Now, I assume as a byproduct of them having 4 tweeters and 4 drivers, they are pretty "revealing", so if you are listening to a poorly recorded track, you know it. They aren't as bad as my B&W 802's for this, but are pretty bad. On the other hand, if it's a good quality recording, you are rewarded with hearing all the little details.


All-in-all, if you are looking for fancy wireless headphones with lots of features, these aren't that. If you are looking for a solid set of over-ears that you can plug-in and listen to digital music on for a reasonable price? These are a solid option. I'm not sure they are any better or worse than others in the bluetooth space, but hard wired using the built-in DAC I think they are a fantastic value for the quality of audio delivered, and this is where they really shine.
 
About a year ago I listened to a pair of Sennheiser HD800S headphones. Completely ruined going forward and nothing I can do to change that. For $1,500 a pair, sigh.

For my money, I have found the Grado line of headphones are amazing for "Heavy" music. I have the 325x and some HD80's I think they are called. Only downside is they are open air headphones, so the person sitting next to you will hear it too. They sound incredible though. My chain is from laptop, to an Audioengine D1 DAC to an Objective2 amp I built myself. The Grados, arguably, don't really need an amp due to their impedence, but I think they sound better with some freedom.

Also, sometimes when I fly, I take some cheaper Sennheiser headphones with this:

Assembled into an altoids tin.....sounds incredible. Honestly. Bonus is sometimes airport security freaks out.

Ha...no surprise, I got a pair myself as well. I concur with most of @OVERKILL 's comments. I will say the active noise cancelling is decent...I like to use them for conference calls, as the mics are good, and with the noise cancelling, it doesn't much matter what is going on in the house and I can keep my conversations going. They are really really decent for music, but I'm not sure they are quite as good as my wired pair of Audio-Technica's

I still use those when doing serious listening, but the Heavy's are fantastic for wireless...I would say the best wireless I have ever experienced. I still do lots of my listening with my desk setup...good thing my bride's office is at the other end of the house.

Is there a chance that AAC has to be manually selected for this BT device?

I got the HD800s to replace my HD598se and imo, the 598 were better "out the box" for music without tinkering with EQ settings; and significantly lighter too. The wider soundstage for the 800s is very pronounced though; 598 already had great soundstage but with the 800s in Warthunder I can really hear an aim-9b closing in 100m away while I'm trying to notch LOL.

Thanks for the review!
The guy that started the company is a former engineer for Sennheiser, lol, Axel Grell.

That's a neat little headphone amp!

Have you tried back-to-backing Bluetooth and the built-in DAC?

I was using Apple Music and the source material is AAC. I didn't dig any deeper than that, so I'm not sure if that's an available option here?
 
so it looks like the current pricing is odd? first pair $299 (-75 first purchase code possible) but second pair for 119 or 60% off?
 
.
Yeah, they are $449 CDN with our cobra chicken pesos.
Funny concindence the owner is named axel, but my axil shooting muffs had similarly hairbrained pricing scheme... luckily I bought 2 and gifted one pair.

Does that odd pricing even work for these.. who wants 2 pairs.. but 1 pair is 299 and 2 pairs is 439
you would think they could sell a ton more if they just made it a flat $169(189?) each etc

Not yet...I have my Audio Technica's, so I primarily got the Heavy's for wireless. I will give it a shot next time I have any decent content to listen to. Youtube is garbage, and Prime is just "ok"...I might try my turn table here at my desk later today. Yes, I know that still won't use the DAC, but should be apples to apples against my AT's.

Oh I'm not sure, you can manually choose on Android but I'm not sure if Apple with iTunes already defaults to AAC.
 
I really prefer reference style headphones with a flatter frequency response instead of the V or U shaped sound signature a lot of headphones today come with. Sennheiser HD600 or HD650's are nice. AKG-701's are another similar option. Both corded, BTW.
