Pros: Build, package, accessories
I´m not good to write something about audio stuffs and to write in english but i hope that my experience helps somebody.
For health problems with my ears, i sold all my headphone stuffs.
in my headphone experience history, i had some good amplifiers like Little-Dot MKVI and a unique and massive balanced beta-22.
I had some headphones like Grado HP-2, Sennheiser HD-800, AKG K-1000, Beyerdynamic T1, Ultrasone Edition 10, Audeze LCD-2, Hifiman He-500 and He-6, etc. etc. etc.
And i tried the famous Stax 009
Why the RHA 750i?
In first place, to use when i drive with my iphone 4s.
perfect for this use.
and, of course, to listen music.
i have in my Iphone Radio Tuna and Spotify.
Therefore a lot of music...for free!!!
Honestly, i will not describe the high, the mids and low frequencies; the separation of instruments, the headstage, etc. etc. etc.
It´s a 100€ headphone amplified by an Iphone and without hi-res music.
Well....I´m really happy with the result.
The headphone is fairly balanced with a powerful bass response.
No metallic high frequencies.
I don´t know the result with a dedicated amp/dac like the fiio alpen that i had.
But the headphone returs very well the original sound message.
In my opinion is a best dela considering the price and performances.
and RHA is an european builder.
In the middle of chinese and us products, it´s a good thing.
