You can do me one, i have an im-70 too.
I have been trying to analyze them both in the pass couple hours on a couple songs. This gets a bit harder than I thought. I will try to put into general findings between these two. The main differences would be
IM70: warmer, more smooth, more extensions, more soundstage, more natural on low frequencies, more beautiful low. Less fatiguing
T2: brighter, less smooth, less extensions, less soundstage, but more mid and high details, more beautiful high. More fatiguing
T2 low: tight, less extension, shorter sub-bass, tighter punch. I guess this is due to the fast decay, the bass doesn't have the sexy full body as the IM70. The T2 bass is more analytical
T2 mid: very well layered, detailed and too forward, kinda like in your face forward, not as smooth as IM70 here, but more details to stand out, and this is where it gets more fatiguing on long listening. With IM70 you can totally relax and still enjoy mid range enough, but it is just too smooth, and as if you was to relax you will get that kind of immersive and wide soundstage here. Together with the sexy full body and extensions of low frequencies, it is just very musical. Back to the T2, I had to say listening to the T2 with it more mid emphasized, I had to be on like defensive mode listening, this is where it get more fatiguing. The T2 however brings out much more details in mid with shorter extensions, it is just too analytical, accurate.
T2 high: very detailed, while being on the brighter side of IEMS, it doesn't get the sibilant, and surprisingly the high extensions are quiet more presenting. This is the strongest point of the T2 overall. Due to this unique brightness the high coporates well with the mid to bring out more details from mid and highs without the sibilant. But listening on the edge gets fatiguing :mad:
Soundstage : T2 feels like you are taking place of the microphone, everything will be around you. I guess you can say narrow soundstage, but you get the details very nicely
IM-70 feels like you are sitting in a live concert. I guess you can say wider soundstage, but some details does get veiled up, unless you look for it.
Conclusion: These two are too different to choose one or another. They both have done well for their designs. Why? With BA it is hard to get smooth and detailed highs, and T2 does too well. With Dual Dynamic, it is hard to get detailed mids, and highs, but IM-70 just do too well. But being a hybrid T2 is lacking out from that Bass, where as IM-70 does not lack behind in the mid and high frequencies. My hat is off toward IM-70 on a well thought design and signature from Dual Dynamic, where as I feel like T2 have room to improve their Hybrid especially in the low frequencies, and the extensions
For below 150$ budget, both of these are very nicely designed, and beautiful sounding. Only too different, IM-70 is more musical and enjoyable with sexy bass. T2 is too detaileds and analytical with strong mid and smooth high. But if you decided to have both, neither will disappoint you in their different signatures and in their own uniqueness. But if you want to keep 1 and kick the other, it is a no brainier to keep IM-70 in my personal opinion.
Both T2 and IM70 are modded. T2 with vents mod, and IM70 with filters removed, using T500 tips.
