The most obvious is not getting the dearer model's textile-skin hard case with pleather trim and carrying handle; or its ear pads' pleathered-up contact patches. The AR5000's inner foam covers go cloth, the outside rims remain pleather but perforate unlike the all-smooth SR7000. Everything else seems the same build, from the plastic for the outer grills to the metal for the actual bodies and bridge, plastic again for the stems which incorporate a 10-click headband adjustment of 3cm range per channel. That also moves the bridge in lockstep so the built-in distance between it and the pleather band remains consistent regardless of height. The 3.5mm cable looks the same except for the AR5000's silver barrels and splitter where the SR7000's are black. The same 6.3mm adapter is standard. With the meat 'n' potatoes seemingly shared for just different gravy, economists will suspect that today's can is a loss leader whilst the SR7000 properly reflects standard profit margins. If true and listening backs up commensurate quality simply from an open-backed loading and associated tuning, the AR5000 should be quite the buy. Though weight differs by just 40 grams, my noggin noticed that the AR5000 is lighter. And what did my ears have on the sonic grey matter? The very first thing was still higher sensitivity for the AR5000; by a few clicks on my Enleum's rotary where I took first proof of life stone-cold out of the velvet-lined cardboard presentation box.

For my listening station here comes the FiiO hosting the AR5000 off aune's 4.4mm cable for the SR7000. My HifiMan Susvara and Raal 1995 Magna snuck in a photo op only because they live here, not because they're at all germane to the sandbox we play in. Ditto the background SAEQ, COS or Cen.Grand. Their pricing puts them out of bounds for the AR5000.
In the same lowest gain setting of the FiiO, with the same cable and only SPL trimmed to account for the SR7000's lower sensitivity, these two performed surprisingly similar. That's a big shout-out for the sealed version. It's testament to the efficacy of its built-in acoustic absorbers aka dragon scales. Just so, differences remain. The first is wear. Likely because I'm so used to the ultra-vented Raal ribbons, the ear feel of the AR5000 with its open grills and lateral slots was freer. It'd be hasty to call them airier per se. That would imply a sonic or resolution shift in the HF. Of that I heard very little, i.e. no different balance in the upper registers. Instead I call it a difference of wear sensation. It's the absence of trapped air with its constant on-ear pressure. That's where the AR5000 instantly registers as airier. I simply don't think that the treble itself is much different. It's the bass gradient which is. That of the SR7000 looks like a teeter-totter whose heavier kid hogs the treble seat. It lifts up the bass end to look like the ideal in-room response of a speaker system. That's where a measured 'flat' response sounds too lightweight; or bright in the treble. It's because of the SR7000's smooth up-tilt in the bass that there's more black in its textures, more gravitas in its weighting, more colour 'warmth'. The costlier version also feels more dynamically enthusiastic still. Is calling the AR5000 the more focussed or locked in the midrange in trade due to that; or because it really is slightly more forward in the mids and presence? I found this impossible to answer when it was a small offset to begin with and only noticed on vocals. Whilst the AR5000 felt a bit leaner and quicker, the SR7000 thicker and more locomotive, these clearly are brothers from the same mother. Given the nature of sealed vs open-backed loading and the classic implications thereof, these two are closer than they ought to be. This does indeed highlight the AR5000 as the go-to buy if as a lone-wolf listener, you don't need the SR7000's not leaking sound into your immediate environment. If you do, rest assured that the Sea Reference won't hit you with any real sonic concessions in trade. Instead it could actually have your vote should your musical diet include a lot of bass-heavy/extended fare. On that score the open-backer treads more lightly.
When that's how the in-house aune cookie crumbles according to my ears, how about their domestic rival FiiO with their 32Ω FT3, a 60mm driver and €349 ask?
