so far I only have a cheap no-name Bluetooth Headset uses. To listen to music via tablet or smartphone (now Xperia Z2) I have always attached a AKG with cable. Well I first tried a high-quality Bluetooth headset.
The sound is for me more than convincing. My standards are high. I hear the doubt no MP3's special FLAC files. I can not detect any sound compromising listening via Bluetooth or plugged cable. The sound itself is for the price m. E. well. I am not a fan of "fashion headphones" a la Beats by Dr. Dre. When in doubt, I expect that the sound without using the equalizer "fits" and representing what is played. Since the JBL comes off well. No exaggerated bass, but heard only the bass, which was also provided. Who is too little, which can indeed still play with the equalizer. Overall, in any case a fairly neutral for me sound / tuning.
The design I find convincing, despite the use of plastic. Who attaches importance on appearance and not as a slave, the "b" requires, is also well served here.
Glad I am to be able to select via cable or wirelessly listen. And if the cable is defective, there is sure to spare. Unfortunately, that was the shortcoming of my favorites so far, an AKG. That part is still functioning properly. Only the permanently installed cable is faulty the volume knob. Throw away because of a 5-Euro-cable is annoying for me. This no longer happens.
The only complaint is the Polsterrung. In warm weather you sweat including extremely fast. Since my AKG was (also plastic pads) better by far. I therefore consider thin foam pad - at least in summer - to pull it.
Overall, however, a strong buy recommendation from me.
