This is how I tested my TH60

Some of my 60's 70's German headphones They are cheap & sound amazing, way way better than Orpheus or Stax or anything (I am sorry:zipper_mouth:) Their headbands & ear cups are made by high quality leather (except the left one & the right one)，same leather as a Mercedes seat, they last forever...

    After the "I just bought a new toy, and it's so great!" excitement had gone, today I switched back to the Telefunken TH30/TH60, then I found that the Telefunkens sound more musical, emotional, engaging, have more soul & depth in the music. I felt I missed something in the music when...

Here's the examples of good sources & bad sources plenty of bass, full bodied, beautiful sound: https://www.youtube.com/watch?v=obsbYMpRkxc https://www.youtube.com/watch?v=filt7u3nRFc https://www.youtube.com/watch?v=nqUyyyQuTZM   no bass, digital, washed out, thin sound...

On good sources(tapes, vinyls, good 1541/1540cd/dacs) the bass quantity of SR is just about right, bass is real & convincing, SR is the best, the king of transducer IMO.   Bass boost is an easy way to have more bass on portables & most sources nowadays(I am sorry, but yes, 95%  of them are...

​STAX aren't that good, vintage German alnico speakers & flagship headphones are better that Stax, but er4sr is superior to all of them

insert it deeply in to the ears,   it will sounds better than all electrostatic headphones ,include HE90

  I mean really, these 6 words killed ER4B,

  Oh you...lol.... you know why there aren't many people buying ER4B?...... It's because your website is telling people, "The ER4B has a diffuse field curve, it's for binaural recording"     But we know that, most(>90%) headphones have a diffuse field curve, included studio monitor...

​The mids are the best I've heard, vocals on my ER4SR are so real   I've heard HE90 & most STAX, and there are no comparison. ER4SR are far better than those electrostatic headphones

      I did a listening test on ER4B, using some sine waves, to my ears, the 3khz & 14-16khz  regions are significantly louder than other frequency too. Because these peaks, cymbals sound too forward, timbre is too bright & thin. With some EQs fixes ,the ER4B sounds like a live...

  Quote:     Thanks very much for the reply, sorry for my grammar mistakes, English is not my mother language. the peaks were shown in the official FR graphs too.   I play guitars, when I listening to ER4S, because the 6khz-10khz roll-off, the dynamic is compressed, timbre...

ER4B/SR bass is the best I've heard, in terms of quality & accuracy   3 reasons why there are not enough bass on ER4: 1. Tips are not deep enough 2.Bad quality source ,.ER4 needs a good vinyl or digital source to get proper bass.(In digital sources,  only a well made TDA1540/1541 CD...

  Quote:   How about when listen to those high quality ,neutral recordings? when  I listen to ER4S, the 6k-10k roll off makes the music lost energy, the sound is flat, boring, I felt asleep when i listen to it. because the mid high roll off destroyed the music instrument harmonics, it...

      The ER4SR is super. On my TDA1540 DAC, it beats my vintage Telefunken Alnico speakers & headphones, the ER4SR is better in almost every aspect, very smooth, delicate​ & real.   ER4SR > vintage Alnico > Electrostatic, in terms of sound quality, timbre and accuracy. it's the best...

My diy pchifi system+Telefunken TL800 speakers https://www.youtube.com/watch?v=3G1ZrRE6YZA     Someone's Vinyl+Klangfilm 405 speakers: https://www.youtube.com/watch?v=oN0ho6bYAzw   A well tuned PC can sound even better than vinyl     My blog(chinese)...

A properly driven & sealed TH600 will sound better than ER4S/4B (& ER4S/B are better than hd540)   I would only recommend TH600/500/60/50 to very experiened users because: 1.A lot of them,about 50%,are defective  (no sound) 2.10-15% sound weird (a high peak at 250hz) 3.Require good...

After TH600 broken-in (just 1-2 days), the  "plastic sound" should gone too.   but to get good quantity bass & good sound, the only way is use them on a high quality source (include HD540,people should not use EQ to fix the bass)

  Sorry to hear that, when seal properly, it should at least fix the "bathroom" sound and those TH600 headphones need a top quality source,like Sony Qualia 010,they are super revealing (TH30 will sound much better than TH600 on a portable player) and please give it 1-2 days to break-in 

I've recorded some Telefunken TL800 videos https://www.youtube.com/channel/UCCOogF34wJcJZo1HWHtxqmw     A properly sealed TH600, the sound is almost as good(or bad?) as the TL800    

if you want a quick listen   try push the TH600 earcups  

    TH600 is like Etymotic ER4, if you do not seal it properly(100%sealed), it will sound like junk

You need high quality digital source or vinyl to get real bass on the hd560 the best vintage sennheier are hd110 & hd224x ,sound is a lot smoother than other Sennheiser   My rating of Sennheriser: HD224x=HD110 when they are properly driven, the sound is comparable to HE90, very smooth ,lush...

sennheiser hd224x

I wrote an "enjoyment rating" in my profile, included hd540 hd560 you may have a look at it: http://www.head-fi.org/u/19408/pkshan
