Review Work (IEM)

Yamaha Eph-100 : Done the right tune

Yamaha Eph-100 reached Earmass!

Yamaha Eph-100 reached Earmass!

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.

It is gorgeous!

It is gorgeous!

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

Bi-Flanged ear tip,Eph-100 is really small and light,thanks to the Micro dynamic Driver!

So here is some specification that I copied directly from the official website :

Driver Type Dynamic, Closed

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”)

After take off the ear tips.

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

It fits nicely in my ears,and isolate well.

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.

Instead of photographing it like how I do usually, I choose to photographed it inside office this time.

It is light,so you can expect good comfort level for Eph-100.

Pairing

Pairing is easy. Find some headphone amp that give you more body,and you are good to go.

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.

Sound Quality

the treble is...Breathtaking!

the treble is…Crisp!

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.

Left and right are marked clearly.

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.

Contoured design body,with a lot of 'up and down'.

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.

Conclusion 

Undeniable, Eph 100 will be loved by majority of listener. It is good and well worth the price point.

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)

Yamaha branding again! I admit I have photographed this logo a lot.

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.

The Yamaha Branding,I love this logo a lot.

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).

No question asked,it is one of the IEM that really performed better than the price you paid,unless you are bass head or true audiophile that maybe find yourself well with a headphone,you should get these thing if it is in your budget.

  2. This is one of the most opposing and bizzare reviews I’ve read on the EPHs..Firstly the standout point of the Yamahas are its bass, and is one of the most enjoyable and “fun”/warm IEMS out there. The only weak point is the treble lacking some energy..Overall though it is a great iem

    • Wait until you listened to KennyG’s songs and learn to know what is good bass, then only you know what I mean here. It has good bass but for metallica or something similar, speed is crucial and clean bass is really not a priority there,

      Thanks

  3. I really enjoyed the review. Very straight forward. I was about to purchase them based on other reviews but I listen mainly to electronic music and probably need a little more bass.
    Any suggestion?
    Thanks

  4. Thanks for your suggestion! I have researched a little and everyone’s agree that there is too much bass? Even though i like it i also enjoy the rest of sounds as i listen to psychedelic trance. i had experience with grado and i loved the sound but here was not enough bass kick : ) What about the dubu d1000 or the Vsonic gr07 bass version?
    Thanks again for your time.

    • Don’t worry for the bass, it is not that heavy, it is more than adequate but in my opinion is nothing near obstructive.

      DN1000 definitely don’t have enough bass, while GR07 (Mine is not bass edition) might not be that nice as well for your types of music.

  5. Hi Su just got the Dunu DN-23 as you suggested and already enjoy them. What a sound for the money!! Cannot wait to see what are capable of after some burning in.
    Thanks so much again for the suggestion. I have sent a message on Facebook to Dunu as well : )
