The HD660 and the HD330, on the other hand, has a more proper soundstage, the size of your average full size cans. The smaller housing of the HD25-1 is probably giving it an unfair advantage here, but on the other hand, the HD25-1 sounds more claustrophobic due to its “signature” small soundstage.

Well, the HD25-1 did what it did best, and soon enough I found out that the bass punch, the focus and the energy is still better transferred through the HD25-1. So that’s one score for the HD25-1: easier to drive. At 300 Ohms, the HD330 and the HD660 are a little harder to drive, and though they do well out of a JDSLabs Cmoy or a Yulong U100, the HD330 & HD660 is slightly above your Ipod’s capacity. Of course I got curious, and given all these PRaTs, I went and compared it to the HD25-1. The HD330 is semi open and leaks sound a little bit. Intellectual property breach on the housing design for sure. But on the other hand, I can also see the merit in the HD330, as it would be a little less extreme, and would probably have a wider genre bandwith. I personally don’t like compromised presentations, and so the HD660 will be the one I use for Rock. The HD330 is also slightly warmer, a tad more relaxed in presentation, and also a tad more relaxed in treble. The HD330 is semi open, and although it gives a better open and airy feel than the HD660, the result is a slightly looser midbass which drops the pace of the headphone down a little. And although I think the warmer and more laid-back HD440 is the better all-rounder for different genres, the HD330 and the HD660 are the sound that fits me better.īetween the HD330 and the HD660, there are slight differences. Not to mention me rediscovering Muse with the presentation that the HD330 and the HD660 is giving. I really can’t find fault with these cans. Say hello to the best Rock headphones under $100.įorward mids, slightly agressive treble, tight punchy midbass. Take the usual standard of Superlux headphone drivers (which is excellent for the price), and tune them to be forward, engaging, and fun with punchy bass. I still have an Alessandro MS-Pro that I keep for yesterday’s sake, and even on a soft-treble amp like the Zana Deux, I still have problems adjusting to the treble of the Grado-made driver. I actually like the Superlux rendition better, as the forward character is not accompanied by the typical harsh treble you get from a Grado. They can be likened to a Grado, except that the fundamentally different driver and housing design keeps them relatively different from a typical Grado. The HD330 and the HD660 are tuned to be the forward and agressive sounding headphones.
