So it's true just not that the need of the adapter Packages dependent on iPhone or Android, but it depends on how recent your smartphone! When Samsung Galaxy S4, for example, the adapter is not necessary, had the S3 to my knowledge probably still the old polarity, for then the adapter is intended. Even older models have no 4-pole, but a 3-pin connector, as a remote control is not yet supported, and for that you can not then make the headphones responsible.
2. Sound quality:
I find the sound quality considering the price balanced well, no more and no less, what do you expect for a 20-headphones ?! I had previously Philips and Creative headphones from the same price range and the JVC are with respect to the overall impression of sound, fit, Equipment for me the most convincing model. The sound spectrum is even at high volumes (which certainly comes in conjunction with the S4 to the limit of acceptable) over the entire range of clean displayed, whom so too lax the bass or the treble are not clear enough, let him but a significantly better model for a maximum of 20 (not 120) call with remote control, then I'll try it from you!
3. Processing / Cable sheathing:
Yes, the cable sheathing is nothing special and maybe that's a good thing. In my experience, are rather soft-rubber or textile-like sheathing, which tend to be perceived as a high quality, much more vulnerable to the transmission of friction noise in motion (eg on previous Philips In-Ears), the hard / rigid sheath of JVC I find this regard exemplary. In addition, the cable is through the base-oriented sheath slim and pleasant after all the Y-fork point is again additionally protected. IMHO this whole "Praemium sheaths" are always just a marketing gimmick, because if you look at the Amazon reviews, can be found at just about any in-ear model 5-10% Customers who get their cable within the first year of use broken , said to have been no matter how many and great Carbon Fiber Silicone NASA special layers this now equipped. For me, the cable hold thanks halfway careful storage always so 3-5 years until a cable break on one of the three pain points and then I have to stop again invest 20, that will not be probably the JVC great otherwise, we'll see .. ,
4. Fit / Other:
- The passport is feeling anyway purely individual, for me are the JVC partly because of the short cable outlet on the earpiece very comfortable, sit tight in my big eavesdroppers and external noise quite well off.
- The wired remote control is pleasantly delicate and light and well placed in the mouth at the right height Höhrerkabel.
- That the jack is just, I think optimally as pocket carrier. While the connector is thus further from the smartphone out as an angled, but without providing further cable bend in the right direction, namely upwards for pocket opening! In addition, angled plugs have often made me problems with the use of smart phone cases with small cut-outs for the headphone output.
CONCLUSION: Safe for purchase recommendation when all around good headphones at a reasonable price and not a magic plant expected!
