Features and specifications
This is a pair of 7.8mm XWB (Extra Wide Band) driver unit offering 5~45KHz frequency response, manufactured with the same diaphragm as IE800 and driving technology:
“Sennheiser’s original IE800 in-ear headphone was debuted five years ago, which was a super comfy, extremely open, natural sounding phone… It’s designed and hand-made in Germany…. The new IE800 S features a single 7mm driver mounted in each ceramic ear piece; impedance is rated at 16 ohms. It comes with a rather deluxe looking real leather travel case. I like … the injection-molded ceramic ear pieces looked snazzy in high gloss metallic grey, but the IE800 S’ ear pieces are finished in a more subdued satin grey. Sennheiser isn’t making any great claims about sonic differences between the two models, other than to say the IE800 S’ 7mm drivers are redesigned. The IE800 S retails for $1,000, £870 and AU$1,600, while the original IE800 is still listed on Sennheiser’s website at $800, £560 and AU$1,200.” Quote from CNET on the impression of IE800.
- 1 Pair (2 pieces) 7.8mm XWB Drivers
- 2 pieces of front cover spacer (for air sealing in installation)
We recommend using them be used with our 8mm Sennheiser IE800 Ceramic Shell or wooden shells.
Measurement is based on an IEC711 coupler, a customized USB sound card and Win10 PC running ARTA Software.
Frequency Response measurement – note the measurement is done with sponge ear-tips, if using silicon rubber eartips, there will be a 5dB boost on 16Khz.
CSD (Cumulative Spectral Decay), i.e., the waterfall diagram. Notice the decay rate at 500hz-20Khz is very consistent, meaning less interference among bass, mid and treble.
Cumulative Spectral Decay
Impulse response – notice the response duration is extremely short <1.2ms, meaning the response of this driver is very good.
Burst Decay – notice the consistency among all the bands
This diagram shows the polarity of the driver. The colored (in most cases RED) soldering panel is always positive side.
Proceed with caution: dynamic drivers are with extremely fragile (1~5μm) diaphragm and can be easily damaged in following situations.
- Soldering: overheated (>250 degree C) soldering iron or overtime soldering (>2s) may permanently damage the driver. Please heat the driver as little as possible during soldering.
- Installation: the driver has Sintered NdFeB Magnetic inside with extremely strong attraction power. The fragile diaphragm may be damaged by having anything metallic hit it.
- Gluing: attaching glue either to the diaphragm or the backside holes may greatly alter the sound
- Chemical: Applying any chemical solvent will void your warrant and we will not be able to help you
- Others: applying high-voltage, storing in high temperature/humid environment… all may cause unrecoverable damage.
