Hi guys,
Can someone compare HD660S2 with HD58X?
Thanks!
Hi, I have both and this is my opinion: The general sound signature is very similar, same amounts of bass/mids/treble. But the 660S2 is, at least to me, quite obviously better technically. The 660S2's treble is more detailed and natural, especially in vocals and cymbals. The 58X has this slight "roughness" to its upper midrange/low treble, 660S2 does not. Also, I feel like the 660S2 has better bass in the sense that it does not intrude on the midrange like it does on the 58X (which I did not consider a problem when I only had the 58X, but I only started hearing it when comparing the 58X to the 660S2). The bass also sounds more "organic" on the 660S2. Also the 660S2 to me sounds like it's slightly more dynamic and punchy than the 58X. Transients also sound sharper and cleaner on the 660S2. Midrange sounds more natural on the 660S2, I would say, due to the "roughness" the 58X has in the upper high mids, which the 660S2 luckily does not have.
So to me the 660S2 is a clear upgrade to the 58X, which is exactly what I wanted. Same general sound signature, just better technicalities of the sound. Cleaner, more natural and organic sound without the roughness.
What is interesting though, is that my friend, who likes his AKG K702 very much, listened to both 58X and 660S2 and he said that he hears no difference. That was only a 15 minute listening session though, maybe that during a proper, longer session, he would be able to appreciate the improvements in the 660S2.
What is definitely better on the 58X is that their frame does not make any sounds when worn. I have quite a problem with how the plastic that the 660S2's frame is made of makes sounds when I wear them whenever I move my head (music masks this luckily, but I can hear it during silent parts and between songs).
Hope this helps and also that someone else can add their opinion
Edit: little clarification that my friend did not compare the 660S2 to his K702 but to 58X
