So I've had my quad drivers for about two days now and I'm actually quite pleased with its performance. I have previously owned the triple drivers and was stunned by the price to performance ratio. And used them as my goto daily drivers. Then the quad drivers come along. They were announced at the beginning of the year and I see impressions from shows here on the forums and on YouTube videos before it's release and man they were getting some cred! I thought to myself at first, man if these come in at $150 that's perfect!! Then they were announced at the $200 price point. I thought to myself hmmm these better be $100 better than the triples. I've read many reviews from all over the web about these quads and most are praising them, some are not. Now do I think these are worth the extra $100 over the triples? I'm going answer with a yes and no. I'll explain in detail why I feel this way. My first impressions (without burning them in) was ok, these sound almost exactly as the triples did with a little more refinement and less bass impact. The bass on the quads have more rumble and dig a bit deeper but impact in the mid bass region is lacking. I thought I could remedy this with a bit of bass boost and found out that's a bad idea. When I applied bass boost the midrange became highly colored by the boost and I mean highly. Then I wanted to why this was, then I read somewhere that the dynamic driver handles both the bass and lower mids. Which would make sense. But the bass is no slouch, it is fast with decent decay and lots of detail. The mids....ahhh the mids. The mids sound to my exactly like the triples but with more refinement and detail retrieval. They are actually quite lovely to be honest. Impressive for the price range. I just wish the lower mids were pushed up ever so slightly with the rest of the spectrum. The treble is where the quads have the triples beat hands down. Amazing extension, amazing detail. But a little bright at times. Don't confuse bright with sibilance, there isn't any sibilance to my ears it me just too bright for my liking. If they could bring down the treble and keep the detail that would be splendid. Nothing a little eq can't fix. Soundstage I keep reading other reviews on the quads and hearing people used the term 3D like soundstage. I'm not quite sure what those people are hearing. I'm not getting that big of a soundstage here. The width is nice. The depth and height are not there. These sound intimate to my ears. They are not by any means a soundstage slouch, they just are all they're cracked up to be in this department. Don't get me wrong I understand in ears can't Mimic over ears. What I do think those people were hearing was the added sparkle and air in the treble. After all that, do I love them? Yes I do, I think 1more has got something here. They have refined and redefined what a v shape headphone should sound like with a price point that should scare the **** out of its competitors. But I somehow feel they just weren't worth the added $100 over the triples. Maybe I'm just thinking in terms of sound, Because build quality is top notch her, most notable is the cable. The accessory package was identical to the triples. I rambled a lot here because 1) I'm on the go and on my phone. 2) I'm not an English major or grammar nazi so please don't judge me! I'd like to know what everyone else thinks. Oh one more note, I am hearing that problem with the cohesiveness between the dynamic driver and the BA's. i will update this as I go along.
