  I think the mid bass is actually a bit bigger in the IM70. The sub bass is definitely better. As far as the MA750, I can't say as I never had the chance to hear them. I thought about them when I was looking at the IM70 and more people seemed to like the IM70. As I understand it, the MA750 is a bit more V-shaped than the IM70 with less midrange and more treble sparkle.

  Thanks for the info! I don't think the A71's would be for me then as I am slightly sensitive to sibilance since I listen to my music slightly loud for the bass. By "elevated bass starting from around 25Hz" do you mean that's when you can start to hear/feel it? Well I'm going to be using these for outside like hiking, walking to class, etc. So I'd kind of like them to have good isolation, how bad is it in the Titan's? Also how's the comfort? the weird circular design reminds me of an earbud.

The sibilance is slight but it is there in sibilant prone tracks.

Yes, I use SineGen to test this. Audible bass actually starts about 22Hz but you don't feel it until 25Hz, and it's very tight from around 30Hz and onwards.

Leakage is quite bad, though outside noise isolation is not too shabby. It's passable for outdoor use. I suggest you don't use them in class or in the library.

For me comfort was a little bit of an issue, but I've gotten use to it. It's similar as with the Xiaomi Pistons. The housing is metal and touches the skin on your outer ear causing a sore spot after a while. Once you've gotten use to it, it is actually quite comfortable. You can were it cable up but it's not ideal. If you use the correct tips for your ears, them comfort and stability is very good. Not as good as cable up though.

Hi guys, I'm new to this forum(in fact I'm new to the field of audio equipment also). My sister and I both own a pair of pistons and they died 2 weeks apart after being using it for an year. After some digging in this forum I was left with moxpad x3 and vjjb. Ended up ordering VJJB 2 days ago because I am not really good with connectors..... the x3 seems like it may detached.
 
I went for the V1S version since I use it with my phone, ordered it yesterday night and just got it 15 minutes ago. That thing looks like a beast! (ilikeiem just beat me to it so I will skip the picture part). Reports online claims high note is not really clear/sharp but will test and hopefully feel the difference.
 
nice to meet you all

Great, great. I'm yet to receive mine. though mine was the first shipped here. Well after all it's coming from China, through a forwarding service. Delays are given. 
 
V1 is looking nice. I am more interested about the SQ. Any initial impressions, please???

I think I should leave that part to other member. If your V1 is not delayed, may be you can be the first who can give initial impression.

It's very comfortable. You can wear it and fall asleep.
