Product Description

Experience Balanced Armature Headphones

Sony has brought together a wide range of technologies to create the Balanced Armature Headphone series, featuring the world’s only Balanced Armature (BA) drivers optimized for music enjoyment. Because these driver units can be freely tuned, they are capable of a wider range of sound, and by combining full-range, woofer, super woofer and tweeter units, they can be layered together for a highly nuanced sound experience. Thanks to the driver’s micro sized construction and high sensitivity, these headphones are able to maximize style comfort, sound insulation, sound leakage prevention and even waterproofing, all while providing great sound quality. Sony BA headphones deliver a new high-quality music listening experience.

Double Layered Housing

The combination of Magnesium inner housing and a special ABS outer housing reduces unwanted vibration and realises smooth sound response to reproduce clear and distortion-free sound, especially in the mid to high range. Double Layered Housing Design allowed Sony to achieve superior sound quality and noise reduction.

High sensitivity for such a compact size

Clear output across a full sound range

Drivers Volume Sensitivity
13mm Dynamic 340mm3 106dB/mW
09mm Dynamic 130mm3 100dB/mW
BA 80mm3 106dB/mW
Compact size

Sony's Balanced Armature Drivers are 40% smaller than the traditional 9mm Dynamic Driver Units. The smaller size allows a design that creates a better fit inside the ear. This attenuates the outside sounds better than headphones with Dynamic drivers, resulting in a superior listening experience.

Sound quality

Compared to Dynamic drivers, BA drivers have an even response across the frequency range, with low and middle vocal ranges standing out. The sound has a very precise feel. BA drivers can be tuned for higher or lower ranges and combined to emphasize certain sounds.



Woofer
Sony’s original sound filter structure blocks higher frequencies while amplifying lower ones. The woofer unit reproduces richer, deeper and powerful base.
Tweeter
A specially designed diaphragm, coil and damper are used to enhance playback of high-end frequencies. The tweeter unit reproduces bright and detailed high notes.
   
 
 
Full Range
The core Balanced Armature driver design produces an even response across the full sound range, with improvements over ordinary balanced armature unit for high frequencies. The characteristic of flat and uncoloured mid range reproduces crystal clear and profound vocal sound
Super Woofer
The super woofer unit improves playback of very low-range frequencies to provide a full, rich bass sound that can be felt with the whole body. It also harmonises each units to reproduce rich expression through all frequencies.

It's been some time since I've reviewed something, but since nobody has yet commented on these remarkable earphones I feel I should.

Firstly, if you've made it this far down the page it's fair to assume you haven't balked at spending a substantial (some would say horrific) amount of cash on a pair of earbuds, and therefore it's probably also fair to assume that you're mainly interested in sound quality. Certainly these top-line Sonys don't subjectively appear to be great value for money at first glance. Earphones aside, you get a small leatherette carry case (which you'll rarely make the effort to use), four sets of Sony's usual silicone rubber inserts (super small, small, medium and large), a further three sets of "noise isolation" silicone inserts (much the same, but with a urethane foam ring packing out the insert to cut down noise), and a cable tidy (little more than a miniature version of the cable tidy found on lawnmowers). The earphones themselves don't impress either, being chunky and somewhat ungainly - though that doesn't make them any less secure in your ear - and made of bog-standard ABS plastic rather than the metal which you might expect for the money. A surprisingly thin wire and chrome effect L-plug complete the "Hmm, is that it?" reaction. They're very much like the Grado SR325i headphones I use at home on my seperates stack, which are equally underwhelming to look at. Perhaps, like the Grados, all the money's been spent inside. I certainly hoped so myself, having bought them on a whim based on their frequency response etc.

So you find the correct size insert (the biggest that will fit in your ear really) and then you plug them in...and it gets worse. These use Sony's new Balanced Armature drivers, which come in single, twin, triple or quadruple versions.

I brought these after my sennheiser Ie80s stopped working after very little use so I thought I would try the sony option. boy was I happy they sound a lot better the bass is the best I have heard all round they are great very clear. In the past I've had sennheiser ie7 & the ie80 plus Beats Tours and the sony's win hands down

Bought these without trying them first as it's so damn difficult to try for upto 100 hours burn in and return them if not liked. I bought these to use with a Sony NWZ-Z1070 ( Japan import ) using flac files
I left the pair playing in a drawer for 4 days only charging when needed and not listening
I don' t believe that when over £500 of equipment should need any form of sound enhancement, so I don't
The first thing that struck me about the xba4 is how forward vocals are almost to the point of being painful
Treble is fairly sweet and Sony have almost managed to tame the sibilance in vocals. Bass is full and well extended and it's a pleasure to hear bass notes actually change note and timbre instead of the scull crushing deep thud that feels that your eyes are about to explode.The bass doesn't bleed into the midrange either The overall effect is that the sound is fast and fluid and makes one want to dance.
It's a good effort by Sony, but I've heard much better The Sennheiser I.e 800 puts the Xba4 to shame. At £600, though, I'd be disappointed if they didn't
It's ashame that the Xba 4 has such a forward sounding ( to my ears) because it spoils a fine attempt by Sony
The NWZ-1070 is a Japanese import with 64 gig and no EU volume cap so worth the extra money if you intend keeping it for some time
