Hi,    If you like the idea of having a open beyerdynamic T 51 p (street safe, hear what your friends are saying, hear the lion creeping up behind you etc)  model of these headphones please vote yes.   If  enough yes votes are ticked , beyerdynamic may take a interest.  ...

  Though the most precious substance to a human is of course water (H2O) as we'd be dead within approx 7 days without consuming any. Though my 8 year old daughter argues that's it's Air (O2). Though carbon has to be up with the most precious also. Only a rather silly economic system would put...

 Nice rounded sound. Spatial (relating to, occupying, or having the character of space)  information (reverb etc)  in the music is reproduced very effectively on these headphones. There is a clear distinction between the spatial character in the music that the Beyerdynamic DT 1990 (open) produce...

Ok. I wasn't specifically refuting your claim as you didn't provide anything to backup your claim, you maybe correct,you maybe wrong,you maybe whatever. But in general ,non-scientifically trained people  can, and do, believe whatever they want about anything and everything they want. Which is...

The D.A.P doesn’t have to be capable of "High resolution" as their is no evidence that high resolution audio is perceptionally a "higher quality" experience for humans. Maybe it's placebo Audio that sells products. https://youarenotsosmart.com/   Just a D.A.P that has  low distortion and...

i5 Specs sheet - http://en.cayin.cn/products_info?itemid=87   Cayin i5  has 190mW+190mW at 32Ω ( click on the parameters tab)

Thanks for the info. In that case the FiiO X5 ii should have sufficient power as it has a rated 245 mW at 32Ω http://www.fiio.net/en/products/41/comparisons whilst according to this site http://penonaudio.com/Cayin-I5 the Cayin i5  has 190mW+190mW at 32Ω.   Though since some believe that music...

Hi,   Are there any D.A.P's that can sufficiently power the  beyerdynamic DT1990 headphones? (250 ohms). i.e- without the need of a extra amp.    Headphone Specifications:   Nominal impedance 250 Ω Nominal SPL102 dB SPL (1 mW / 500 Hz) Max. SPL125 dB SPL (200 mW / 500 Hz) T.H.D.< 0.05%...

Could prove useful information for others.

"FiiO X1ii - Worthy Upgrade?" I've recently just "upgraded".  I wanted something a little smaller.   The other main differences  of the x1 ii ,like the touch screen scroll wheel don't help much as far as managing/playing/finding music is concerned.   Upgrade if you want a  smaller player...

Hello,   Which headphones would you consider to be most like the following:   1. Capable of producing a Frequency response of 14 - 26000 Hz (value of hd518 for comparison).   2. Constructed to last with a slim and light form factor (maybe blue-tooth).   3. Open to the sounds of the...

  Thanks for the post, the info on how the RS1e maybe not so popular is interesting though purely speculative.   Of course people have a individual preference when choosing a particular sound signature, though my above post is specifically about the quality of sound in relation to Grado's s...

Hello,   I own a pair of Grado SR80. Thinking about the upgrade to the SR125e E series. I've  browsed this thread and there is the all too common "They sound better take my word for it" response (Donald trump style rhetoric). Though I haven't see any actual recorded measurements.   Quote...

Being a fan of the genre electronic music (especially deep/progressive house) it's a refreshing change to find some music that features lyrics based on evidence (The album Symphony of Science Collector's Edition is Good music for children or people whom are new to the vast genre that is...

Budgets not currently a issue with ultra portables as all I have seen to date a comparably inexpensive. Though I'd pay handsomely for a improved version of the sennheiser px100's II. Better components,smoother more tactile ear padding, wireless ( Micro technology allows the player to be...

  Yes belief can be quite comforting and provides hope to many. Yet self understanding ( Biology; Evolution;Ecology;Astronomy etc)  can provide insight and hope that there is so much more we have yet to understand about our existence.   Vanities and ego's can easily be mitigated with...

Hello,   I haven’t been reading the forums for a while. I'm interested if there has been any development in the ultra-portable line of headphones. By ultra-portable I'm referring to headphones like sennheiser px-100 II's & Ultrasone HFI-15G's etc.   # open back. # Light weight. # low form...

Great Thread.   Belief is such a inferior thought process compared to understanding. 

Thanks chupacabra314. That difference was produced by an oversight  .I hadn’t achieved a decent air tight seal.   Doh! I feel like a Muppet now (not a fool though ,as I learnt from my mistake). Oh well,at least listening to music with the correctly fitted westone 30's will quickly...

I stand completely corrected ! . I'm human thus prone to making mistakes. In this case it would seem I have learnt from them :-). It was simply a problem of the supplied tips not quite fitting correctly. So,even though the IEM's felt right they didn't sound as they should due to a lack of an...

  ( I did not have a air tight seal)   I did not state that the W30's did not have sufficient bass for me. The music track I compared the W30's on had been produced using a technique called side chain compression. What this does achieve, on this particular track, is slightly lower the...

  I couldn’t decide which to purchase, the W30's or UM30's. I eventually went for the W30's as I enjoyed listening to music with the original W3's. I'd also read they were similar, though more level, overall than the Westone 3's .   (Incorrect as I had an incorrect fitting seal)As I...

Thanks for that info. I've just ordered some A83's. As I prefer the cable over the ear design. I'll compare them with the 30's and decide which to keep.

Edit: Please note the below review is flawed as I hadn't acheived an air tight seal on the westone 30's at the time ( though I thought I had). My later review (several posts on) is more accurate.   It's a learned skill to be critical ,especially when you want to like something like an IEM you...

I've just ordered some W30's. (past owner of westone 3's) .   There will never be a perfect IEM,headphone etc etc as the word perfection is an absolute and there is no evidence of such a state ever existing,thus perfection is probably an imagined anthropogenic ideology (amongst many many...
