Many thanks for your answer. I dont have a great experience in headphones yet.
My first headphones i purchased many years ago was a studio monitor from AKG. "The reference phones of the radio stations". This reference headphones sounded so lifeless with nearly no bass to me that i instantly lost my interest in headphones.
One day at my work at Philips Medical Systems (ultrasound) i received an old system back from one of our customers. I checked the accessories box and found a new sealed "Koss Porta Pro" headphone inside. As noone wanted it i took it home and tried it out with my awesome iRiver IFP-795 MP3-Player. That was the first time i discovered that headphones can actually have bass.
After this new experience i purchased "The Plug" from Koss and found out that in ears can have great bass too. My interest in head & inearphones was back again.
Next headphones were the beyerdynamic 770 Pro 80 Ohm. I really enjoyed the headphones. Due to some other interests my music listening time went smaller and smaller. As i was working very long in front of my Pc i recognized that im really missing listening to music.
I bought the Fidelio X2 and the AKG 712 Pro. The Fidelio X2 ist still my prefered open headphone (of course, i dont have a closed one atm) for daily Pc use. I did not get warm with the AKG 712. Too less bass and a bit too quiet mids.
The Sony Z1R must be a nice headphone but not my price range yet. So i narrowed my selection to the Monitor 5 and Denon AH-D5200/7200.
If the SEM5 sound is not thin and boring as you said and is a step up in bass in comparison to the fidelio X2 and beyond the experience with the AKG sound signature i think it can be my favourite. Before i wrote this i found out that theres a dealer called "Hifi Klubben" in Cologne which is not far from me. There i can listen at least to the denon headphones i have chosen. I chose the denon 5200/7200 because i red that they are the updated version of the "audophile Basshead cans from Denon". Dont get me wrong i dont want a too boomy bass in all my songs. I listen to every kind of music. I experienced that i like a present bass at nearly every genre. For example: When im listening to Metal-Music i want to hear the punchy double bass. If this is too thin, quiet or non present i cant enjoy the music.
This is not my prefered music but i recognized that its a very easy track for me to hear if a headphone satisfy me with the bass qualities. Its "Lil Wayne - Lollipop" After 20 secs there is a bass that can sound very nice and satisfying with good quality bassy headphones. If this track goes deep with the Monitor 5 i guess i will like it. Bass with the Fidelio is nice with this song but the deep frequences get lost a bit. Maybe because its an open headphone? Listening with Yamaha EPH-100 in ears the Lollipop bass is also very enjoyable.
I also like detailed high frequencies. If i put on a new headphone and easily discover the details without deeply focusing to just hear them im happy. But if the recording and artist ment the highs to be so delicate i did not say anything. Thats ok. I dont want any frequency to sound unnatural load. ... so i need a neutral sound signature. (with emphatized bass, mids and highs that reveal all details and dont sound harsh) <---
Puuh. I hope i find my "fun-headphone" with either one of the new Denons or the Monitor 5 (which should have really good mids as i red)
How is the difference about "lush" and "neutral" mids? Are the neutral mids more quiet?
