I got them just for curiosity, but after using them i was quite impressed.
I'm a trebble head so they are not my favourite (look for the B2 if you like trebble) but they have nice bass, airy but not too much bloated, they have a nice impact without overshading the others frequency.
Is enought detailed for not be disgusted.
Really reccomanded for people that like bass but still minds the mids and highs
After i got this headphone i wasen't that impressed, i read many review talking about them like the neutral champ but maybe i was hit by the hype train...
The construction isen't that bad but not as good as many other cans.
After all for the price they sound quite good.
The bass is well balanced but the treble and vocals seemed to be a little bit owerpowering on my ipod touch 5th gen.But you know ipods they have a crappy eq so its almost impossible to get a good balance when you need.So I blame the ipod on that one.The vocals on this one is just unmatchable and unbeatable I have used a pair of jays and they are well above as far as the price range goes but these m4 pairs are in par with them.So cheaper but same vocal deepness.Another thing is the sound stage,you can hear and differentiate each instrument and you can clearly visualize the placement of each instrument at the time of the record.So another plus and thumbs up on that one too.
After having some trouble getting the right tips, I ended using the Comply : even if the M2 are not the most comfortable IEM, with a below average noise isolation, I really enjoy the warm sound of the M2. It's not too bassy, but fun! Precision could be better. Noise of the cable could also be reduced, but at this price, I can't think of anything really better.
I am very disappointed in the sound quality of these Delta very poor. Even worse than the headphones Canen for $ 3. Bass a little (but I did expect), in the high frequencies are played with a lot of distortion. Some tools are not heard. Earlier I bought proalfa. They are just gorgeous. I also bought R1, they are a little worse, but still good. I did not expect that the delta will be the same, worse than expected. But they are just disgusting. This is my last purchase brainwavz not believe corrupt reviews.
