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...
