So, I would say that these rank up there with my Cardas A8's in terms of fun and clarity. The A8's add a touch more clarity, but the Kinera's give you a little more in quantity; in terms of bass.
The Kineras don't stand up to the FLC8s' in terms of clarity, but they do have a much hard-hitting bass.They have equal soundstage; which is impressive. IF you listen to electronic; of almost any sub-genre, you'll be extremely happy with the Kinera. I have the KZAte and the Magaosi K3's as well. The KZAte's are much warmer and veiled in comparison. The K3's are brighter with less bass. I don't think the K3's are any more clear, despite having the extra BA, and have a tendency to be a little too sparkly. All in all, of my collection, with my amps, and my subjective perception of sound, and also taking 100 listening sessions, how many times would I grab the following headphones:
1. Legend Omega 30/100 "pure and sweet" $1200
2. FLC8s 30/100 "vibrant and fun" $300
3. Cardas A8 20/100 "bass dream" $200
4. Kinera BD005 10/100 "for a good time..." $30
5. CKS1100 6/100* "full sound" $125
6. Magaosi K3 3/100* "bright and precise" $140
7. KZ-Ate 1/100 "one-hit wonder" $25
*NOTE: with my Soundblaster E5, it has some good EQ-ing that can be done. When I tweek the EQ of these headphones, I can get a really good sound that could improve the rating. This is worth noting because, if an EQ is all it takes, that means the headphone hardware is highly capable. Consequently, they're a very good headphone, I'm just am not crazy about how the manufacturer has EQ'ed them in production.
I've had many, many other IEM's, but without having them to A-B, I don't think its fair to offer comparisons.
Although the Cardas are placed ahead of the Kineras with a seemingly large gap, I would actually place them very closely. I think I grab the A8's so much more often because I paid so much more for them, so there's a psychological thing happening there. I also think the CKS1100 may be a better "audiophile" headphone than the Kineras and is closer to the A8's. However, the CKS isn't as well suited for Electronic and is more for music with vocals and acoustic and the like.
