Earmass had heard a lot of good thing regarding this Yamaha Eph100 long before it reach our place. Seeing that Eph100 has really created a bunch of good follower among audiophile,and all think that it is really good regardless the price. That is why we are working hard to find this IEM to review.
Thanks for Mr.Sim from S.L.C.G Enterprise(Kuching) for lending me this unit of Yamaha Eph-100 for reviewing purpose.
This review will be mainly done with simplicity and straight-forward only because I only receive this IEM inside a pouch,and there is no box and any other accessories, so there is no other ear tips included as well besides the one that is sent to me,the Bi-flanged one. It fits my ear,and I can get pretty nice noise isolation,so I think it is my size.
Specification,Design and Build Quality
So here is some specification that I copied directly from the official website :
|Driver Type||Dynamic, Closed|
|Driver Unit||Φ6 mm (1/4”)|
|Sound Pressure Level||104 dB ±3 dB|
|Frequency Response||20 Hz – 20 kHz|
|Weight (with Cable)||13.5 g (0.46 oz)|
|Cable Length||1.2 m (47-1/4”)|
|Connectors||3.5 mm (1/8”) L-type mini stereo, 6.3 mm (1/4”) stereo|
Eph-100 employ a micro dynamic driver which is very small,Design wise,it is good looking and made by high quality aluminium material and can withstand a lot of hit and scratch,so this IEM can last you long as long as you not overly or purposely break it. Cable is good,and I found its cable is less prone to tangle.
Noise isolation and Comfort level
I only can tested this by using only pair of ear tip that is supplied by the owner. I can said that it can isolate plenty of noise outside and fit securely in your ear.
It is light,so you can expect good comfort level for Eph-100.
This earphone is easy to drive,but without amp I think it is way too lifeless. I also thought that IEM should be done it simple,but I gave out because for me it is too lifeless and not enjoyable directly from my Hippo Biscuit,so I plug it through the Govibe Minibox (Old Version),and it is a good match. Personally think that Jds Labs CmoyBB V2.03R will be a better choice.
Pair it with Musical Fidelity VcanII and VdacII,the sound is leaner and high is better extended.
Yamaha Eph-100 has been tested by pairing it with Govibe Minibox portable headphone amplifier,Stoner Audio UD100 Dac,Creative Sound Blaster Go! and sometimes straight out from my Hippo Biscuit player.
High : I have so much to speak and praised on the treble of the Eph-100. It is crisp and really presence. It is not mark up to give you ‘detail’ illustration,but it its treble is really detailed and so comfortable to listen to. For me,high frequency is the best things of Eph-100,and it is nicely extended.
Mid : It is blessed by good level of detail,it is clean and clear as you can expected from this micro driver. Vocal is average,a little bit to neutral,thin and light vocal reproduction. Guitar sounded nice. Relax and clear sounding.
Low : Low is good if you are not bass head or expect dynamic/slow decayed bass. It is quite solid and tight,but obviously this is not a bass centric IEM that will excel in Top 100 song, the bass decayed a little bit too fast and lack the details,also depth. Overall,it is good.
Sound Signature : Eph-100 sound is not forward sounding,it is laid-back but fast. It has some distance which I think is good for long listening period. Generally I think that Eph-100 sounds is fast and accurate,some listener told me that this might be a V-shape sound but I am disagree,at least to my ears,its mids is not recessed and bass is only boost by a very tiny of margin. Overall it is clear and spacious for a IEM. As I said,it blessed by impressive detail level.
Sound Stage : Its sound stage is typical for a IEM,fail to bring up ambience of a live recording,but not bad and better than some.
Instrument Separation : It is good.
Tested tracks are all in Lossless format unless otherwise stated.
Baby come to me – Kenny G Ft Daryl Hall (At Last…The Duets)
Instrument and vocal has good seperation yet integrate nicely. It has sense of distance as well. Honestly,the bass hit with good body and has good texture.
单数，刮目相看 – Gary Cao
Vocal is good and it is fast. Maybe it is too fast,so it is a bit less expressive than I would like,but generally it is good.
Meditation from Thais – Yoko Fujita/Keiko Ogura (Stradivarius The Sunrise)
Lack a little bit of detail and clarity if I compared to Shure Se425,but Eph-100 play this quite good and violin sounded lean.
Good : Treble response is superb and crisp, well placed price point,Detailed and good instrument Separation,All frequency sounded good,clear sounding,Yamaha Branding on the housing,Material (Durable)
Bad : Lack some ‘excitement’,Bass head will not like this,Not rich sounding.
I like this IEM,from outlook,build quality,price point to sound quality.
First,it has some really good build quality and most importantly,it is comfortable and fit securely in ear,isolate plenty of noise. Of course you will still heard some ambient noise, but it is really good. The material Eph-100 used can withstand scratch and drop (not purposely done,might damaged the driver and magnet inside anyway). So after purchasing Eph-100,you can less worried on the matter of durability and focus more to enjoy the sound quality.
Eph-100 has good sound quality. Honestly,timbre is not my type of liking,don;t get me wrong,it is good,but not the type that I like. Overall I prefer something that is fuller and thicker,not like those on the Bowers and Wilkins P3 though. Besides my personal preference,I can say this Eph-100 has good sound with good clarity. I can’t say it is neutral,but it had done a good job to keep all three frequency band in good sound. Bass is not prominent like what you expect but the overall sound quality of it is good,and I think it is far beyonds its price point,which is Rm560 (150USD).
