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.

I have ordered my Sony XBA-4iP after a really deep research and I had a very high expectations.

When they arrived, at first I was very disappointed with the sound quality. It was very sharp, without any energy and the bass was barely there at all. And then I have read a very useful reviews, saying that these headphones need some 'warm-up'. And this is totally true. After roughly 10 hours, they started to sound better and better. The bass appeared and then became deep and vibrant. The bass/mid/treble levels stabilised. They sound absolutely astonishing!

They are worth every penny! Be patient, don't judge them right after you get them out of the box. Wait, give them some time to 'warm-up'.

UPDATE - DAY 3:
All the above was true, as long as I kept them connected to my stereo system with the equaliser set-up properly. Today though, I connected them to my iPhone to listen to the music on my way to the office... they sounded awful :(

No bass, the treble so loud and sharp that they were painful to listen to. I tried all the available iPhone equaliser settings and nothing. The sound was terrible. I'm taking away two stars for what I've heard today. I'll give them a few more days to 'run-in' before I decide what to do.

THE VERDICT - 1 WEEK+:
Ok, I kept them playing non-stop for more than a week. They improved, but not drastically. They can sound very, very good, when equalised properly, but connect them directly to your iPhone or iPod and you may be disappointed.

It's obviously a matter of preference, but for me they lack bass and have too much treble. The high tones can be so intense, they are sometimes painful. I'd prefer 30% more bass and 15-20% less treble (but as I said it's my personal preference).

Normally, when you spend extra cash on premium earbuds, you get a "professional" Neutral-sounding tone, which you'll probably end-up EQ-ing before you've got the sound you want (extra bass perhaps, maybe sweeten-up the top end).

However, these buds are aimed at the consumer, and sound great, straight out of the box. Tight, deep bass, lots of detail, and a smooth top end.

I've owned Shure 535s, and Kiplsch X10s, plus one-or-two other higher-end 'buds, and these provide a far more pleasing tone.

No doubt the sound is very good. The fit could be better - am using the large buds. Not sure if I can tell the difference with the sound-insulating ones - they are less squishy so can become uncomfortable over a period. I used these earphones for 35hrs each way long-haul from UK to Brisbane. Nice, open, neutral and detailed sound - could do with more bass which is surprising considering they have a sub-woofer. My last pair of Atomic Floyd Hi-Def Drums were great but one cable wire must have frayed inside control housing (gutted) and the only reason I found myself purchasing another pair - I did my extensive homework and these came out tops almost every time. They are NOT worth £320 as per Sony website but at about half-price I can justify these - great deal on here. They were bassy but heavy to wear in the ear - excellent feel, look and quality. The Sony's could do with a better looking design, a bigger pouch too as if you have the cable tidy AND the clothes clip it's a real squeeze to get them in the case. However as for sounds they are very good at dealing with all manner of music but make sure you feed them with high quality music signal or they will rip that music apart and make it sound awful. Extreme quality Spotify and the like comes through crystal clear and with very detailed nuances that help justify the earphones price - worth a go - again only at half the price of Sony's RRP.

Many years ago Sony made the MDR-E484, legendary earphones - a few years later the MDR-E888 was born, using biocellulose drivers, again - impressive at the time... (to give you an idea, check what these go for on eBay!!)

Then they had a dry patch, MDR-EX70, EX71, EX700 - all 'okay' but not fantastic, then came the Sony MDREX1000 Monitor Headphones with Noise Isolation Earbuds...

Fantastic as the EX1000 are (as you can imagine from the cost on the link above!), the treble can be described as brittle, splashy or bright - the XBA-4 corrects what Sony (in my opinion) did wrong! - solid bass, rich mids, crisp, nicely extended treble and an insanely wide soundstage, for the first time in many years, these IEMs made me jump, the sound was so left field in this case, wasn't expecting it at all! - these are what Sony is all about, top quality items!

I will confess that I needed to have the Comply Tx-200 Isolation PLUS Earphone Tips With Wax Guard Medium Black 3 pairs eartips to get these to sound their best, but - what is another £20 investment when you're spending this much anyway??

Oh, and the specs on mine (made 11/2012) are different to those shown in the guide above, so - could be a revision...

XBA-4ip :
Type : Quad-balanced armature type sealed
Sensitivity : 102dB
Playback frequency band : 3-28,000 Hz
Impedance : 16Ohms
Maximum input : 100mW
Mass : About 8g
Open circuit voltage level: -42db (0db=1 V/Pa)

Anyway, if you're in the market for a balanced armature IEM, but cannot afford to go custom, give these a try, you may just find that it is worth having some faith in Sony after all!!
