They cost $230 and hit about the same on an identical track and settings as the xb90ex which are really peculiar and do not hit hard unless set correctly. Strange since they are "XB" series marketed 16mm with 200mW max input. They will hammer but it's not as easy as it's marketed to be.
The 7550?
I enjoy lachan's vids a lot and don't really watch anyone else. He likes and see's the ma900 exactly as i do so i have an idea of what he likes and can use that to either agree or disagree with him as his general opinions seem fairly consistent. I just saw this vid 2 minutes ago and didn't know about the felt in the 7550 but I also liked the 7550 more than the 1000 for the reason he stated as well....the highs.
(done with video)
The 7550 have a max input of 500mW as well...that's ******* nuts. The EX1000 are 200 like the xb90ex. That spec really only comes into play when pushing a set with an amp.
I have only played with them but will soon own a set and am fairly sure they will be the hardest hitting IEM found so far. When the xb90ex get warm in my ear from a Cayin C5 on high gain and bass boost on the 7550 did not. Folks can wait until i get them and share exact settings before they invest but they are better than my Sony A2 in stage/presentation and bass.
All the IEM on the impact list need an amp and eq. The 7550 can take a lot of both. A LOT.
I heard both the 2 and 2.5 before buying the 2.5 and thought the lack or rolled off sub-bass was unacceptable. The bass range is the shortest numerically and having a portion of the 20-35Hz range rising instead of elevated turned me off. The bass tracks i listen to often have multiple hits from 35 to 55 to70 but above 75 the bass is more of a sound than any thing that you feel. That being said it is a list and not my thing alone and the asg 2 are bass beasts. They should perhaps be on the list. Which set to you think they should replace on the impact list?
Honest question. Opinions and input is welcome. This list is still evolving.
Will do.
JVC is a strange beast. They make magic but never when they try. Hardest sets to place may be theirs and a lot of their stuff could fit on the no amp list. Will continue to modify that list
