Bluetooth:
The link to my smartphone went very easy, you had to install only one app, switch on the appliance, connect and you could start right away. At KH himself some functions attached that only work when the unit, including the volume.
The sound on BT:
For Info:
I use the power amp application on my Xperia Z.
Audio files are mostly in FLAC format, or with 264kBit / s AAC with 44.1kHz.
Depending on the musical direction the sound is very good, detailed and almost flawless.
This includes:
1) "Wicked Game - Chris Isaak" Rock
2) "Machine Gun - Chase & Status" Drum & Bass
3) "the most of our resources - Kool Savas" Rap
4) "Freek-A-Leek - Petey Pablo" Hip-Hop
-> Top!
However, also shows the disadvantage of BT. Especially fast, strong rock - sound appears at BT rather weak and prone to itchy sound.
This includes:
1) "Long Forgotten Sons - Rise Against" Rock
2) "Ghosts - Celldweller" Electronic Rock
3) "Money - Serj Tankian" - Rock
-> Flop!
The sound via BT with iPhone 4s / 5s:
Having heard about my Xperia Z now with BT music, I have yesterday at 12:02:14 tested also times on the iPhone of my friend or a mate to sound. But first a little to "Pairing" with iPhone. (Press and then make a long power button) to activate Bluetooth on your iPhone and KH switch pairing mode. Then connect and you immediately hear music. One thing of 1 minute, max. . 2
The sound via BT when iPhone is a lot better than my XZ via BT. I tested then compared 3 songs and deliver this direct to the XZ:
1. "Breakdown - Breaking Benjamin" Rock
2. "vigilante justice - KIZ" Rap / Hip-Hop
3. "Hollywood Hills - Sunrise Avenue" Pop
-> Top!
Sound via cable:
When used with cable noticed that the already good sound is represented more clearly and precisely in rock - music where the KH is weakening at BT, shows its strengths with a nice gentle bass and analytical list of all instruments.
Pure listening pleasure!
Conclusion:
BT is particularly suitable for slow, electronic music and chanting as Rap / Hip Hop.
About cables all styles of sound perfect.
BT, however, the iPhone was sonically better than the XZ.
Since the coupling with both Apple and Android was just a test of the sound on BT is clearly recommended.
The test with the iPhone and slightly better sound I raise the rating of KH to 4.5 stars, so rounded up to 5 stars.
