At the same $799, the obvious contender is the also recent and hyped Hifiman HE600. How does the D1 fare against HE600? My genres are opera, classical, jazz, R&B, then some light rock and pop. ---

Anyone compare the D1 to the HFA Dahlia sound and comfort wise . The only headphone I own is the Audioquest Nightowl Carbon and I’m wondering if I’ll miss that dark but melodic bass if I buy the D1 ? Thanks ---

How does the D1 compare to the DT 1990 Pro mk1 in terms of detail retrieval? I love how detailed the 1990 sounds, but I wonder if the D1 would be an upgrade. For context I listen to the DT 1990 with the analytical pads and the treble peak doesn’t bother me. I also love the tonality of the HD6XX. ---

Looking at measurements, they should be pretty similar. DT1990 also has almost perfectly tuned midrange and great bass. One huge difference is that famous 8kHz peak. ![IMG_1914](https://us1.discourse-cdn.com/flex016/uploads/headphones/original/3X/f/c/fc97dc46f46c0d335b6d625368fc0136f296edac.jpeg) ---

Am thinking of a “battle royal” involving the following headphones now all at or around $800: HEDDphone D1 Focal Clear Focal Hadenys Meze 109 Pro HFA Dahlia Hifiman HE600 DCA Aeon 2 Noire Audeze LCD-2 Classic This is what it would take to get the Meze out of the ring: ![image](https://us1.discourse-cdn.com/flex016/uploads/headphones/original/3X/1/4/14c73b1d6236ab920cd8fea4f8bbf87a4d0663b3.jpeg) ---

Thanks for the graph. A part of me wonders if the D1 provides both the tonality the HD600 and the detail retrieval of the 1990 Pro, or exceeds it. If so, Heddphone has another customer. ---

Thanks for the great review Listener! Do you have any EQ suggestions for fixing the treble of the D1s? ---

The Arya Stealth at $600 should be in the list as it can even exceed a lot of those headphones at cheaper price. ---

How would you compare the dms omega, focal elex to the d1? I like both for slightly different reasons, but would love the elex sound with like 2 month old pads with better build and driver quality. ---

I believe Andrew touched on this comparison in the video review on our channel! [https://youtu.be/Nt\_Cw7ofXRQ?si=eYGzoOPHV1s\_qBGX&t=796](https://youtu.be/Nt_Cw7ofXRQ?si=eYGzoOPHV1s_qBGX&t=796) ---

Fwiw I think the 490 Pro gets a higher grade from Sonarworks because its a better EQ platform (more bass in stock formation), not that it’s more neutral. I don’t really like HD 490 Pro’s sound, so D1 is a clear winner considering the build/comfort is comparable. ---

Realistically its all about finding where the peaks are on your own head and cutting them if they’re an issue. ---

I compared it to Elex in my review but only w worn pads on Elex. Elex w worn pads is bassier/slammier but less neutral in the mids and less “complete” sounding in the treble. Omega is just… kinda worse overall, thinner mids, overblown bass, rougher treble, meaningfully worse build. ---

Where is that review posted? Il go gander. The omega treble is a bit sharper, its an enjoyable sharpness on my head mostly, not like the 109 with the constant sizzle to every note. ---

I rather like the HD 490. The HD 650 is still my favorite Sennheiser. The D1 sure looks like a excellent option. ---

really wish they used a magnetic pad system or just a less scuffed one, possibly similar to the one on the para (without the inner stuff, just the outer magnetic ring) ---

The battle at 8 hundo is fierce: ![image](https://us1.discourse-cdn.com/flex016/uploads/headphones/original/3X/c/0/c0bdfa5d69d0add50e62cb2b364d4a8aa27e931a.png) I’d love to see these squigs on the [Headphones.com](http://Headphones.com) team’s rig. In the meantime, this is from Gadgetry Tech. We have a few visible outliers: Hadenys has a larger bass boost; the 109 Pro looks a little warmer in the lower mids and has the 1.5k dip; Dahlia has the biggest peak at my beloved 6k, and so on. But in truth there is a lot of similarity here. Most are following the target fairly closely through the mids. IMO all of these are good headphones. Looking forward to hearing the D1. ---
