Well I LOVE Havi's sound with my X3 II but come on... Cracking after only 2 weeks? Disappointment is real.

Hello everyone, I was using my Havi with my Fiio X3 2nd Gen and I was really happy at all. Both of them are real beasts in their own ways. But my Havi iems are cracked quite a long time ago (actually just two weeks after I bought) and I started to tape them but it's getting closer to die at some...

Okay, I am stupid. I realized that I didn't insert the detachable cable correctly. It needs a little bit pressure to sit. You have to hear a "tick" sound. After that, you turn the cable and it's locked. Thank you for your attention and I am sorry.

Hi, My HD598c arrived today but when I listened with it, it sounds so bad. I'm not a headphone hater, it sounds like defected. I don't know how a defected headphone sounds but it sounds so much steamy... Is it about burn in? I had my AKG K612 two months ago but when I first listened it, it was...

Okay, I'm not alone. Most probably this is about the playback quality difference between foobar2000 and X3ii. It's like the music player software in X3ii is somehow inferior to foobar2000. This is not a big deal for me since I'm having this issue with my full-sized AKG K612 because it's my...

A quick question. My X3-II sounds better and (if I'm not mistaken) louder through foobar2000 when my X3-II is plugged as DAC to my desktop computer than X3-II only (DAP function) Is it only me or is there a logical explanation about that? My computer is onboard crap when it comes to sound card...

Depends on your satisfaction. Actually, NX1 is a good amp which have a moderate power to drive some serious headphones. It had a high swing if I'm not mistaken. But since K612s are basically ''no sensitivity'' headphones (~90 dB) they love extra power for more headroom. For example, my X3ii...

I own this little good boy named X3ii for a few months and I love it. But I wonder, how is the build quality on long term? I mean,a couple years. It feels really solid in my hands but just wondering. Considering it won't be dropped to anywhere. 

I got what you say and I'm sorry for my over-concern. This will be my first headphone amp and 110 bucks are not ''that'' cheap for a university student like me as far as I've already bought my X3ii, which was a fantastic value though. And since my K612 is a real power hungry, I'm literally...

Thank you, sorry for late response. There are so many topics here. When you say more controlled, precise sound with less distortion with K5+X3ii compared to X3ii, it's easily perceivable/audible with my AKG K612 right?

I'm ordering a Fiio K5 for my K612 in a few days to pair it with my X3ii. That amp seems like it can give K612 juice more than enough. Not to mention that it's pretty cheap. Ideas? Portability is not my case, I need an amp only at home with my desktop computer. I'm also using my X3ii as DAC for...

Have fun!  I'm gonna buy a Fiio K5 soon, I will share my experiences about the effects of K5 on my AKG K612. Honestly, I'm wondering the ''true potential'' of this headphone too badly. I'm really digging it even with my X3ii only

I think you can feel slighty warmer sound if you boost low frequencies. Or you can lower the upper mid range. But the terms like warm or cold are characteristic things, it's not directly connected to EQ. But a headphone amp can make our source warmer at all, Fiio amps are neutral though. (if I'm...

HE-400i is something like 35 ohm/93 dB, which is easier to drive compared to my K612 (120 ohm/~92 dB) but if you find HE-400i quiet with X3ii it's interesting because I rarely listen full volume even with my K612 and I prefer listening to music really loud as well. But if you're talking about...

I'm the proud owner of X3ii but I compared it with X5ii a few days ago, I did my comparisons with my AKG K612 PRO and DT 770 (250 ohm) of my friend. Both DAPs sounded so similar as neutrality, clarity and detail. But X5ii has a very slight edge on instrumental seperation. X5ii about warm...

Yeah, I'm getting used to EQ boosting these days, especially foobar2000 EQ features are great. I'm gonna buy K5 instead of A5 or E12 I think. Other than higher volume, what would be the amp (K5) effects on X3ii with AKG K612? More controlled sound?

Thank you for your time, appreciate it! I will give you my feedbacks if/when I buy K5 :)

Thank you! I'm closer to K5 as well. I got some information about the technical problem that we face today. You can look at my thread, starting from post #14: http://www.head-fi.org/t/831995/fiio-a5-e12-or-e12-diy  

My musical taste is metal music, which means plenty of instruments. Especially for progressive metal. I'm a guitarist for this kind of music as well. The main thing that I'm uncertain is headphone amp effect on X3 II. Is there a difference in presentation between X3 II full volume and X3 II +...

Actually I knew what you said but same power with different peaks made me confused. Thank you for your correction! I'm using my K612 with my X3 II and my listening level is just between 110-120 (according to song) on high gain every time, which means there is not any headroom left. What are...

I thought about your first scenario but if that was true, it should be more powerful @300 ohms, right? I mean, if their peak voltages are different, their certain power for a certain impedance should be different I guess? Second one makes sense imo. Did you use both of them? Which one do you...

Now I am awakening this thread. I need help from you experienced Head-fi members for some reason... E12 is stated as 14,96 Vp-p and 150 mw @300 ohms. K5 is stated as 20 Vp-p and 150 mW @300 ohms. What? After solving this one (I hope), which one of those amps should I buy to use with my X3ii...

It's been a long time since this thread is started from you but that's the thing I'm wondering these days. K5 is stated as 150 mw@300 ohms, E12 is the same but K5 is like 20 Vp-p where E12 is 15 Vp-p. Isn't there a problem here? I mean, when it comes to 32 ohm, K5 is something like 1,5W...
