Roxanne sounds warm, overall quite balanced. The sound signature, specially the mid and treble resemble my JH13 FP and JH16 non FP to a very large extent. Before I get my roxanne, I heard that roxanne is more mid centric compared to the JH13 FP. This is not true to my ears, although JH13 sounds brighter. Actually roxanne's mid range is a little bit more laid back compared to JH13. JH13 is more forward, but the combination of the forwardness and imbalance of mid and sub bass prevents me from enjoying the bass of JH13, I am glad that roxanne doesn't have that problem. My JH16 non - FP (with Twag) can produce similar type of bass as the Roxanne with 70% bass gain, but with more clarity and air in the presentation. Anyways, what I am trying to say here is if you already JH13 or 16 and wish to buy another CIEM, roxanne is not for you IMO unless you want adjustable bass alone, because it's definitely not a upgrade over 13/16 to my ears.
One thing bothers me the most is the treble extension of JHA. I just don't hear it.not in JH16, not in JH13 certainly not in roxanne either..where is the super extended treble everybody is talking about.....
In contrast, K10 is more accurate and neutral. The mid and treble are so much linear compared to roxanne's. In detail, K10's mid/upper mid is more forward giving you more emotion and fullness of the music, in terms of vocal position, body and brightness. Roxanne has up and downs above 2K Hz here and there. K10 has a little hump too at lower treble region (but very little), same as JHA product, but the clarity, imaging, transparency, micro detail and resolution is greater than roxanne due to the better/linear treble extension. So it doesn't give you the feeling that instruments are thrown all to your face rather than a well balanced presentation through the whole spectrum region. K10, a musical/smoother IEM actually sounds a little bit brighter than roxanne.
To me, accuracy is the key to enjoy music (providing the music is well mastered). In this regards, K10 surpasses roxanne for me.
