I am in the market for a neutral, closed, and sealed pair of headphones. I am not looking for an overall upgrade, just to fill a small gap in my collection. For the record, I will mostly be driving these from an Asgard connected to a Bifrost, but also will occasionally be using a C421 (OPA2227) connected to an iPod 5G and ODAC. All of my headphones are listed in my sig.
Closed cans I own are the D5000, MrSpeakers Mad Dogs, DT770 Pro 80, Pro 900, HFI-780, and HM5. I certainly do not want to sound nitpicky, I am just really trying to fill this gap in my collection. I realize no headphone is perfect and I enjoy all the headphones I currently own (I sold off the ones I did not like). The D5000 are fantastic, but they are far from sealed, the bass is just a hair too loose, and the highs are just a little harsh. The DT770 Pro 80 has slightly boosted bass and slightly recessed midrange for me to call it neutral. Correct me if I am wrong. The Pro 900 are obviously very boosted in the bass region and have harsh highs. The HFI-780 are also v-shaped and not as detailed as some of the others. The HM5 is not very detailed in the midrange (sort of veiled) and a little too dark. I plan on selling my HM5 very soon.
Then I get to the Mad Dogs, which are closer to what I am after and are good in their own right, but not exactly what I am after in a neutral, closed, sealed can. They do not isolate very well and they are too dark for me. It is my darkest headphone and I tend to like a sound signature that is a little brighter, especially when talking about a neutral can. I believe they are too dark to be considered neutral. Once again, correct me if I am wrong.
I have been considering the following as my neutral, closed, sealed headphone:
- AKG K550
- Logitech UE 6000 (wish the earpads were replaceable, though)
- Sennheiser Momentum
- V-Moda M100 (pretty much ruled out as they seem very bassy and not too detailed)
- AT A900X (from what I have read, the K550 seem a better fit than these)
I have almost narrowed it down to the K550 or the Momentum, but am very open to other suggestions, especially if you lack experience with these or have more experience with others. InnerFidelity seems to place the UE 6000 above the K550 and Momentum as the better value, but I am not seeking a better value. At the same time, I do not want to break the bank, so I guess I would set a budget of around $300 or $350. I am after the most neutral, closed, sealed headphone with the most detail and highest fidelity.
I am not sure if this helps, but the headphone I consider to be my neutral open headphone is the DT880 Pro 250, but I do realize the highs might be considered by some to be a little too boosted to be considered neutral. I also just picked up the HE-500, but do not have enough experience with it yet to determine if it is more neutral than the DT800, but I do absolutely love it so far. Maybe someone knows which is more neutral?
Thank you in advance for your help.
