i has been using sound magic e10s for almost 3 years..its sound signature is balanced n packed with decent amount of bass..its very much comfortable to wear for longer hours.it has also strong build quality..as it has taken some wear n tear i decided to upgraded it with sony mdr x75..i came to know about headphone zone by my friend..i must tell u all that headphonezone is the place where we can buy branded earphone n headphones which can be found nowhere in india and are much affordable .. i bought my brand new sony mdr xb 75 here.. customer service was very responsive n courteous..coming to sound quality after usage of 12 hours in poweramp app with bass boost. as soon as i wore it it let the beast out ..i felt the base is very deep n booming n punchy n pleasant as well but not at any expense of mids n clarity..thats where it stands out whereas mdr 55 is far behind.. despite heavy bass it boasts it never has failed in maintaing sound quality even at full volume..so dont listen to it at full volume because its such a loud iem that it can impair ur hairing since its sensitivity s 112 db..but only problem l have faced is that after listening to it for long my ear canal starts aching since driver is bigger ..neverthless best iem in terms of base n clarity within 4k..i am delighted with my purchase..headphonezone team may develop headphonezone app in future because it will reach at many more people..thanks to headphonezone team ..☺

both may look same.even both may sound same.but lot of difference is there..1.xb75 driver is little bigger than xb55.. 2..xb75 has a aluminum housing for driver as mentioned in sony website where as xb55 driver is aluminum coated only.. 3..xb 75 has a bass duct that is absent in xb55 4..build of xb75 is lot stronger than xb55.. pictures are also uploaded for the differences between these two i have mentioned above
verdict-these r reasons why xb75 costs rs 3900 which s lot higher than that of xb55☺

HEADPHONE ZONE
Oh! boy, This people are Simply MAD i tell you why, i was lukin for Sony MDR XB75 coz i lost mine in transit, I spoke with them (Executive Salim and other guy) they suggested me to buy RHA MA390 but since i was not sure about its quality so they invited me to their studio gave me RHA MA390, Beyerdynamic Byron and some other too..Just to check if i like any of em...but since i am type of Bass head and was habitual of using XB series i stuck to it...since they dont sell product from studio they requested me to order online, I ordered Sony MDR XB75 On same day evening and wud u believe it..very next day morning it was in my hand..i mean how can u b so Mad at your service..u guys gonna really screw up competitors...Guys a point to be noticed that wen i visited their studio it was pin drop silence..which shows they are dealing with 0% Customer Complaint and 100% Customer Satisfaction..coz they dont sell products they just BUILD Relations.

Here comes Movie Experience Tested Atmosphere scene, Mall Scene, Railways Scene, Horror with panning, last but not the least War Scene with some gunshots, bombs droping, and chopper fyling all around u r ears all are just Awesome..I did not find this headphone lacks in any of the segment, may it be song or movie.
Build :- 10/10
Looks :- 09/10 (Color seems a bit towards dull side)
Comfort :- 9/10
Overall :- 9/10 (For Bass Lovers)
Mic :- 10/10 (Captures the sound which is more than 10mtrs away from u)

Verdict : Get this headphone and feel tiger roaring just beside u.

Sony xb 75 Ap is a awsome earphone ... it's only for bassheads lover ..the bass like boom boom

Sony XB75ap earphones gives you crystal clear sound effects with superb extra bass. awesome sound effects even small sounds are very clear.
awesome movie watching experience.. feel like watching in home theatre.. excellent hearphone.. &
Headphonezone is just amazing. received on time. excellent customer service. price is really good compare to other e-stores and outlets. kudos.

Earphones are extremely great. Need to burn in for 50+ hours to unleashing true nature of this beast ( Bassy Sound ). Highs and lows are cleanly audible even though bass is super punchy and booming. Design also good and carry pouch is nice too. Go for it.

Awesome bass punch. Feeling like a theatre and produces real bass echo's. Best for bass lovers✌️ Money worthy. Good package from headphone zone
