[Xperia Z Q&A, Help & Troubleshooting] Sujan Baruah:
ex300ap is NOT 'big' on clarity dude

First of all thanks for the comparison you did above but i would like to clarify this to anyone who gave more attention to your details on the ex300ap. I have both the mh750 and the ex300ap (so am kinda more on topic to this thread :P . If i am to compare this two then i would say the following things,

Bass on the mh750 is more mostly because of the fact that there is no leakage of air between the driver and the ear drums once inserted (this is the reason why both the mh750 and the mh1 is so painful in the ear. Especially the vacuum effect while pulling out). The ex300 on the other hand has a very different design. The way it enters the ear and the way it remains there is something to praise. I didnt know inears can be comfortable too until i tried these. The vacuum effect is nil, insertion is easy and it stays put without causing any irritation. Although i would advice to use a smaller earbud (take from your previous inear sets maybe, as extra ear buds arent provided with this). This helps to insert it much deeper. And unlike the mh750, inserting it deeper isnt painful as the air gets out to maintain normal pressure, same goes for taking it out, no more POPing when pulling it out. Volume is a bit less (vs mh750), but not too less either. Am using it on my HTC One X and i cant reach max volume without the risk of experiencing pain, so its good enough. Xperia Z phone itself is too quiet, the headset isn't at fault. Overall signature of the sound is kinda dull (although not as dull as the pathetic sounding mh750). Clarity and mids are more pronounced in the ex300 so definitely its an upgrade in sound 'quality' but this doesnt mean its perfect. Better than mh750 yes.... but sound quality isnt something to write home about. I have a sennheiser HD202 so i know the meaning of clarity. Using the ex300 on flat eq is not advisable. Rather apply a U shape eq or 'rock' eq to get a much much better experience (keep the mids untouched if possible, basically make the U shape 'above' the base frequency line on the equalizer, not through it). The ex300 is more flexible with equalizers than mh750 which no matter how you mess with it the output just doesn't sound pleasing. The thing that makes the ex300 stand out is its wider soundstage. I have used all stock earbuds of all the manufacturers (sony, HTC, samsung, LG, nokia) and these are the best in this aspect. The sound will keep getting better till it reaches full burn in. I just recently bought the ex300ap. Build quality wise the plug on the ex300 is much better while the cable is thicker on the mh750. Quality of cable on the ex300 isnt bad but can be snapped easily by the looks of it. Cant expect any better for the price. The larger 13.5mm driver does make a difference as the sound seems more fuller, kinda like am listening to a over ear headphone. There is no distortion on high volume or bass. Has the ability to extend very deep (as far as 15hz). Bigger driver also gives a very obvious advantage. That is if the earbud does get a bit loose, the sound doesnt go too quiet or too low on the bass in an instant like other headsets. This keeps us from fidgeting with the earphone too much to get that 'perfect' fix or sound every time you move your head. So basically am very happy with it.

Mind you, am only making these comparisons with stock earphones only because these are very good value for money and are more useful (having mic and button as an added extra). Very cheap price just makes it impossible to complain about anything at all. Each of the above can be had for much less than 10$ on ebay (Ebay india cost for ex300ap is 300-500 INR, the mh750 200-400 INR). THAT cheap.

If i am to rate the two then here goes,

Bass: 4 star to the mh750/ 3.5 star to the ex300

Mids: 2.5 vs 3

Treble: 1.5 vs 2.5.

Am basing the above rating to my sennheiser HD202 which is my current best for the type of music i prefer. Usually all those R&B, HipHop, pop, rock, country, bollywood (basically everything that doesnt have mad men shouting in it like those heavy metal kinds).
