Yes. A-Bing right now with the Serial. The output volume is the same as the H50. However, since the 50 is simply the brighter pair, it sounds that the mid is recessed.
Whilst on the Serial the Mids are the star of the show, will sound like they are that forward, but not by very much.
This is a bright track esp. the re-issue versions. It is sibilant on the 50 and thus need to tip roll, not on the Serial.
regarding the Serial....
I testified my very first thoughts in the Serial thread exactly a week ago upon very first listen straight out of the box.
7 days later I can say :
HOLY COW !!!!!!!!!!!!!!!!
What an amazing piece of work!
what a brilliant earphone that is!
I have left it burn in for a week without listening, mostly for 90 hours or so.. and the frog turned into a prince!!!!
From all of the iems in my possession the SERIAL changed the most after thoroughly and extensively burn in procedure.
furthermore I had to try numerous tips in order to find the best result in terms of transparency and emotional vocal response
a lot of tip rolling there......
I have never experienced a change in tonality and sound profile like that before with any other iem I ve got.
the vocals/midrange came to life and what I had originally thought about the Serial (veiled / thick midrange /not a Penon house sound) has now changed dramatically...
warm, analogue, true to life presentation
Very very emotional transparent vocals
The depth of the stage is truly admirable.
the coherency of the drivers is excellent
the bass is simply exceptional
the detail retrieval in the midrange is outrageous.
sure.. it may not have the ORB's sparkle up top and maybe sound a bit darker in tone, but it is an absolute monster of an iem ready to handle any genre with ease and finesse.
a week later I feel dazed.. but not confused any more.....
the most unique feature of Serial to my ears is the depth and height of the stage something hard to achieve to my small experience and knowledge..
the more I listen the more I find more quality elements in their profile..
A week later I tested it (between other sources) with an older combo of mine Fiio X3 dap & HUM Hypno class A amp.
Hypno amp injects some color into the midrange making it more analogue than ever.. That resulted in a super sonic audition with excellent dynamics, I had never experienced such a dynamic presentation before with other iems using that combo.
Due to that unexpected change in tonality/profile of the Serial I have started burn in H50 as well for some days now...
nevertheless first impressions from H50 were pure awesomeness all over the place...
