Been listening to 1Plus2 almost a week or two now. Haven't really contributed much lately so here's my two cents.
1Plus2 sounded bit "compact", it sounded as if everything was compressed together. All the details were still there, but as time passed by this compression loosened up. To be honest, I would have to say it used to have bit sharper characteristics in overall, especially bass. Now those sharp corners has been sanded down, it's really smooth yet accurate but not bloated by any means. In a sense it shares similar trait as IE80 or EX1000; it fits right in the middle. It's not bloated and too smooth like IE80, but at the same time it's not too thin like EX1000.
4.Ai and 1Plus2 doesn't really share much traits. 4.Ai holds its ground against 1Plus2 pretty good. Both are smooth and balanced or whatever you'd like to call it. Is 1Plus2 really better than 4.Ai? To be honest, it's personal preference. I own both, like both, and can listen to both at any given time. Do I favor one over another? Not really, mainly because both excels are different things.
4.Ai in a nutshell
- Everything sounds bit closer
- Good imaging
- Lack of bass "thump" (obviously because it's BA)
- Sometimes songs sounds bit washed up.
1Plus2 in a nutshell
- Airy (vocals)
- Everything sounds bit further
- Good imaging
- Bass "thump"
You may disagree or agree with the following points for each IEMs, but it basically comes down to preferences. If you don't like bass thump and want as much as micro-detail as possible then 4.Ai is definitely for you. But if you enjoy BA IEMs for details but also need some bass, then I would high recommend 1Plus2 over 4.Ai. By all means, this isn't for bassheads. It's not muddy and bloated like IE80. To be honest, I don't really care what people says about IE80 and EX1000 (I own them both); neither will ever present details on BA level. 1Plus2 obviously can do this because it has BA drivers. Best of both worlds really.
I've had FitEar ToGo! 334 for many months, it simply is one of the best universals ever. I personally rank it extremely high, it's close to being the Holy Grail of universals. I own both, I am just a humble enthusiast, not a MoT or sponsor so I have nothing to loose by favoring one of another. This is just my personal perspective, so I hope none of you take it too seriously.
334 in a nutshell
- Good imaging
- Lack of bass "thump"
- Mid-centric to a degree, but not really. I can see why some people may say that.
Some may view 334 as just another multi-BA IEM while 1Plus2 differentiates itself by being a hybrid. I'd agree to that, because that's the simple truth. 334 indeed is just another multi-BA IEM, but it's one heck of an IEM. Detail wise, 334 still wins hands down. For a BA its bass is... really well done. If you really want to listen to music without adding or subtracting anything then 334 is probably your best bet. Totally opposite from 1Plus2; a polar opposite I must say. 1Plus2 makes music sound fuller, and smoother. Overall, I'd have to say 334 is more energetic and 1Plus2 is more laid back, bit more relaxing per se. Different IEMs for different preferences.
This basically concludes my personal two cents, tried to keep it as simple as possible (no audiophile mumbo jumbo). Hope this helped.
