How can you refuse a review whose argument goes,
"You tried making on an experimental basis the year mold for the MDR-EX70SL, but as for external auditory meatus length the pattern where shortly you can obtain the frequency balance where the pot is satisfactorier."

The SONY * MDR-EX70SL
The year receiver for the iPod, it seems that becomes examination item even with each sight, but in inside at SONY make " MDR-EX70SL ". With the year tip/chip of the silicon make, simple encapsulated type. Also size is very the wearing impression with small inclination.
The year tip/chip section be able to do the removal, adjusting to the size of the ear, exchange is possible. Whether the ǧ - the Çfi, this year tip/chip, the name machine of the past years, you can use with the SONY TE-ST55/5C6b system, * & * (it is the hearing aid, but laughing).
Concerning sound with the sound quality where sufficiently satisfaction goes, most because of encapsulated type, outside it becomes masking noise invasion of noise to be little, also not increasing sound even inside the streetcar, it was possible to enjoy.
On one hand, with encapsulated type the Occulusion Effect occurs, overpressure value near 250 - the 500Hz rises, but moving other than contact and the gnathal joint of the tooth, by his occurs the sound where is easy to offend to the ears the point that. In addition because from cutoff of the aural signal from outside, in the aspect, danger perceiving ability decreases largely, as for utilization in the midst of and the like walking it is necessary to avoid.
You tried comparing the difference " of MDR-EX70SL " and iPod standard year receiver wearing.
The left does not inhale the year receiver of iPod standard, the right SONY " MDR-EX70SL " (, by mistake it increased, * & *) from the ÉnÉi .
The year receiver of iPod standard type diameter to be large a little (for the American market?) May be also a case whose being settled is bad in the one where the ear is small is.
In addition with the general receiver of such type, is stored to the ear concha cavity prevention of falling off of the substance which takes maintenance in the tragus and the antitragus it becomes the style which, but seriously it says that direction of the driver it is adjusted to external auditory meatus direction, the weak point which.
In addition because the air gap of the external auditory meatus becomes large, in addition to the fact that transmission loss of sound to the tympanic membrane occurs, because also environmental sound outside invades, with the environment whose especially around is noisy volume itself is increased tend.
It is the style which in general type such as iPod standard year receiver stores the substance to the ear concha cavity, does the maintenance for falling off with the tragus and the antitragus, but because the air gap becomes large in regard to external auditory meatus blockade, as for the sound pressure which is transmitted to the tympanic membrane decrease. In addition with driver diameter, when fitting to the ear changes, size is large, at the time of the bulging of the earring leg, accompanying pain with long time wearing.
On one hand, with " MDR-EX70SL " we obtain maintenance by resistance of the external auditory meatus and the silicon ear tip/chip, because it becomes the style which closes airtight the external auditory meatus, as for driver diameter itself to be somewhat small as for transmission efficiency to the tympanic membrane we are good, adjust to the decrease of residual external auditory meatus capacity, can obtain the sufficient volume impression.
Depending upon the air gap of the external auditory meatus, to be attenuated tend low the limits come out rather it reaches the point where, but this comes out too somewhat, is the disliking where Bu - becomes with me the feeling which. When it can fumble with this and the equalizer, furthermore it does well and (the vent opens and ÇÍ ÇÍ time is and with does but). Remainder not to sound livelily, in order just a little about for moderate volume to be suitable, you think.
In order with " MDR-EX70SL " to maintain the year receiver with the external auditory meatus, in order the small ear even with is easy to fit, in addition the external auditory meatus to close airtight, it actualizes the efficient transmission to the tympanic membrane. The part which from the substance is connected to the cord/code you use the silicon material, éÏ tack and just are fitted to also the mark.
" It makes shortly the band, is long to make being less crowded ", as in indication, the case where at the beginning you inserted in the pocket of the back and the pants, the just a little routing was troublesome. " Then replacing to the tobacco rather " in the pocket of the chest, when you try inserting, there is no excessive play at just size, the comfort. If you inserted the wheel surface, before skip / what calls also halt the OK was ascertained (removing from the pocket, while looking at the picture with, when it becomes, being after all just a little to be short, it does, but * & *).
It receives the mail, in regard to music appreciation and danger perceiving by the year receiver when walking (Kubota, thank you!) You tried measuring the smallest audible threshold change when music is designated as masking noise, making use of the assistant listening effective measurement equipment.
The Lyon corporation assistant listening effective measurement equipment " HF-03 ". Originally the case where the hearing aid is done it is the equipment which is used in order to verify the effect, but it measured the naked ear (wearing it is not) with, at the time of time * stop of the performance of the MDR-EX70SL and the iPod concerning.
Originally from the speaker it measures at distance of the 1m, but lowering the audible threshold of the high pass naked ear, in order to look at the change with year receiver installing, you tried measuring at 2m distance. As for measurement sound it is not the pure tone and we have become war bull tone.
How practicing, well, it cannot hit the fact that it chooses in masking noise, (the proper?) Good Times Bad Times of Led Zeppelin. At volume position of the lower picture it measured.
Many times hearing, the ÉhÉâÉ~ÉìÉO be too enormous of the É{ÉìÉ] the Good Times Bad Times which skill it is possible. As for volume when such as 7 partitions.

Unit: Measurement failure below dB SPL & 20dB SPL
Appeared is airtightness characteristic, e.g., with the measurement result with the naked ear and the smallest audible threshold comparison of each year receiver when stopping, with the MDR-EX70SL you can see the rise of the 15dB in every the 1kHz/ 2kHz, (as for environmental sound 35 - the 40dB). With the iPod standard year receiver, although you can see somewhat rise with high pass, as for difference of the naked ear in the result which almost is not.
It is change when performing, again, but, this was surprised trying measuring,, but big change appeared in full circuit wave number zone. With the iPod 50 - 55dB smallest audible threshold rises concerning 35 - the 45dB and the MDR-EX70SL.
When while it is non consciousness in such state you walk throughout the city, it is very dangerous, you think) whether (perhaps there is the note writing even in the instruction manual and the like. While walking and, use of the year receiver please avoids regardless of the product, for danger evasion absolutely on the on stream of the bicycle * motorcycle & the car. When in state of that one it springs out that way outside, whether it meets to unexpected accident, the ǵÇÍÇ‹Ç
From Newton @-AtMark- and Sugiyama concerning the fretting noise of external auditory meatus airtightness and the cord/code the mail receiving, (thank you for!) The case of movement such as walking, when limits sound offends to the ears rather low with the movement of the cord/code, it received indication.
Whether as for the MDR-EX70SL in order with encapsulated type, for there to be times when the Occulusion Effect becomes remarkable, itself utterance and gnathal joint gliding * hinge * rotation sound and occlusion sound resonate, at the external auditory meatus soft section are times when it offends to the ears in the same way overpressure value in regard to the fretting sound of 20 - 30dB rise and the cord/code in the frequency band near 250 - the 500Hz, the ǵÇÍÇ‹Ç
From the above-mentioned reason, the silent limits (peak not only the cord/code near the 400Hz) in, the heel when walking hits against the land, you verify and sound and the sound, from the vocal chord " ÉSÉb and the ÉS Éb " (you attach the year receiver and " the ÉE - " with try saying and as the watermelon thinks), the gnathal joint and the sound where the tooth hits (as for this way when äö it is with you look at the gum and the beef jar key, * & *) and so on, when various sounds offend to the ears.
It is such sound, but because with noise the masking it is done by the fact that overpressure value of identical frequency exceeds that with music and the volume which are heard, when volume keeps lifting, above a certain fixed volume it stops becoming matter of concern, (when sound is not inserted in the opposite direction from the year receiver, you think) whether most noise becomes matter of concern.
You think whether there are times when noise of such silent limits is easy to offend to the ears depending upon volume and use style. In order private to be the car & bus * flight inside of a plane even at when moving, the dangerous aural signals from the outside relatively outbreak are few, you think also the noise occurrence risk due to the moving of the body / fretting the cord/code is small, at the environment that, in the future utilizing will try you can obtain the margin for the masking of the sound in addition by environmental sound.
From the Oura way with the similar encapsulated type year receiver, the high-class machine which makes faithful playback of the sound source prime object, you taught Etymotic Research corporation " ER-4S ". (Thank you!) When you try inspecting, as been introduction at the place of the WAO AEDIO , the pattern which is handled . It is about it cannot put out the hand price as expected but you think (laughing), as for improvement of airtightness characteristic it produces year mold in the MDR-EX70SL, would like to try trying soon.
You tried making on an experimental basis the year mold for the MDR-EX70SL, but as for external auditory meatus length the pattern where shortly you can obtain the frequency balance where the pot is satisfactorier.
With the work example which about the 8mm leaves external auditory meatus length, after all fretting noise of sound and the cord/code of our voice of those which rise gain is remarkable. As for position inside external auditory meatus of driver generally the same as the ear tip/chip of normal?
Finishing to think, when almost you try cutting the external auditory meatus, the being confined of the limits to fade low, in satisfactory balance. Also fretting sound of the cord/code becomes moderate.
In external auditory meatus long reduction edition distance of the tympanic membrane was far somewhat, could obtain sufficient volume. In the sense, invasion of external environmental sound, because it is there is a vent effect in the driver itself, as for big sound insulation effective change in the external auditory meatus it was not recognized.
If low from risk of excessive boom of the limits due to closing airtight to the external auditory meatus first curve, to blockade the ear concha cavity, method of approaching that, it makes external masking noise decrease, as a balance perhaps, (it is the 8mm, because there was no thing where balance deteriorates largely, perhaps this) there are times when it is good, problem of the taste.
