Any **** V2 and SONY MH755 (modded mmcx with cable) owners here? I can't decide which one should I buy for casual use only, I will only use smartphone as my source for listening huawei nova 3i to be specific. The reason my choices are limited because I don't like over the ear type iem and the two that I mentioned are the only that I can buy with my budget. Which one should I buy? Which is more close to blon b03 and tfz t2?
You know, that's an interesting question. I have both the MH755 and original Y*nY*o V2 (1st tuning).
The MH755 is probably closer to the BL-03 in terms of tuning. Both are Harman-esque, I think, with the BL-03 being more towards the Oxygen I'm told. I compared the BL-03 with the MH755 directly, and they are both on that spectrum. Definitely the MH755 has a 'natural' tuning where instruments just sound right. Surprisingly, it also has decent isolation, if you can get a good seal. Those are its strengths. Because it's a little 'thin' sounding for me, even though the bass is decent. It's also prefers AMP/DAC/DAP setups, as it benefits from more power. It's gentle, and I can imagine myself using the MH755 at nighttime to go to sleep.
The Y*nY*o V2 is not Harman-tuned. This isn't a big deal for me, Harman is just one nice tuning among others. I would say the OG V2 took a 'neutral' tuning as a starting point, and then made it more 'musical.' It's basically a Tin Audio T2 tuning but they played with the shape a little to make it more fun. I used to take the V2 everywhere with me, because it's really easy to drive from a mobile device. It doesn't need power or amping.
Fit of the V2 isn't very problematic, but I found it an absolute necessity to use foam tips in order to get the best seal. When you get a good seal, you can hear the uncluttered and complete V2 sound. I use Comply 400 tips. Size 500 might fit better, I'm not sure. Like others have said, the V2 is good for the more relaxing music, playing it softly and melodically. It's thick and warm, and can give pleasant vocals. It has better bass than the Tin T2, so it doesn't feel as if you are missing out on the pop and indie rock.
The V2 is probably a better IEM for mobile phones than the MH755, but it's actually pretty close. The MH755 might beat it in isolation for some people, although I wouldn't really want to drive it from a phone. V2 comes with a useful case, and MH755 doesn't. But you're taking a risk with the third and final tuning (currently available) because some say it is more boring and generic than the original V2. I'll know more when my 3rd tuning arrives.
