strong striking resounding, blechernder sound in Bluetooth connection, a KO criterion

Have the same problems with the BT05 Sound Marketers, as I unfortunately could read only after the purchase in one or the other reviews here (I am a bit too much on a 4-rating).

The sound via Bluetooth simply tinny and reverberant. As you would be in a laundry room, as if a lot of noise - especially heights -. Very strange filtered out or minimized in the short term (swallowed) are, the volume varies quite minimal between different pitches within a song!

A pity, I find that it DeleyCON apparently fails at a digital Bluetooth connection to sound correct 1: 1 transfer. Think this is due to some compression methods. I have multiple Bluetooth devices, dongles, etc. Among others the following for mobile use Philips SBT75 / 12 Bluetooth Mini-Speaker for iPad / iPhone / iPod / Android / tablet / notebook / smartphone (battery) black and Raikko POCKET Beat 2.0 Bluetooth Stereo . mobile mini active speakers including battery (2x 3 Watt, microUSB, Line-IN) and black for the home: Logitech cordless Music Adapter for Bluetooth audio devices and also 2 other cheap dongles from China ...

... And none of these devices I've ever had such problems!

Back to deleyCONs:
Via supplied cable, the sound very loud and clear, as I imagine, but also expect and presume !! No Hall effect. But my main reason for buying was the wireless aspect and that you can skipping songs by the buttons on the headset. That this problem only when radio plays notice (as I read in another review), I can not confirm. I want to order 95% listen to music and the difference of Bluetooth cable is unfortunately Gravital, there have certainly been in direct comparison (during the same songs) 10x reconnected, the difference in sound falls every time a tremendous ear!

Furthermore, it is absolutely incomprehensible for me that the reviews of the On-Ears are thrown with the in-ears together in a pot. Those are 2 different products that need to be evaluated very different by their very size / nature / battery life / sound, etc. (this is none Falls Rating affecting)> ergo urgent action on Amazon!

Conclusion: If you want to use the headphones with a cable, could access at the product (however, there are also better in the price range of wired). For those who prefer a modern cordless Bluetooth version without annoying cables position while laying on a clear sound value, stay away and keep looking!

Addendum: I have tested it with the Galaxy Note III. In another review, in the reviewer had the same problem with a HTC One & Galaxy S2, this reverb with a HTC X8 has (the mind only the Bluetooth 3.1 standard has) no longer. But I wonder if the BT05 Sound Planters (ausdrücklick as Bluetooth 4.0 touted) compatibility problems with a grade 3 from the date of the flagships (of course Bluetooth 4.0) and various other devices have, as future-proof then this deleyCON headset?
