Hey there! This is my first post so be gentle with me haha!
I am wondering to buy a new pair of headphones to use with my mobile phone, the Sony Ericsson Xperia Arc S. After a long time looking for the perfect headphones and at same time learning about sound science, I decided to choose the Sennheiser PXC 360bt, which looked cool, seamed to have a great noise cancellation system, great sound quality, and what at first look seemed good, they had Bluetooth, so I could listen them without cables and with a supercool quality with the aptX codec (obviously, all this is reflected in its price, €160 in the cheapest website).
First deception, the aptX codec was not supported by my mobile phone, the Sennheiser support said me that I could listen them with "standard bluetooth quality"; it's ok, I like "standard" things, haha. But after googleing, I've noticed that the BT quality is not the same as the quaility given by a 3.5mm cable or an USB (obvious? well, i'm quite stupid), as the BT just gives a max bitrate of (correct me if I'm wrong) 320kbps; and here's my first question, does that mean that if I'm listening to music via BT I will never be able to listen at lossless (.flac) qualities, like 1000kbps or more? If so, BT is a joke.
Luckily, the headphones come with a 3.5mm cable to connect them to the device, that's a good thing, so I could listen to my favorite songs with lossless quaility via cable connection, and if sometimes I need to use BT, I'll have it. Another question I have is about 3.5mm cable and USB; I heard that USB gives a higher bitrate than 3.5mm, is that true? If so, is there any adapter for 3.5mm to micro-USB (you know, that one that you use to connect your phone to the computer...), and would it really help to increase the sound quality?
In summary, is it worthwhile to buy a pair of headphones with BT technology, which I don't really need, even if they bring the 3.5mm connector? Because maybe for same price I can get a one with cable connection and with better sound quality. What do you think? Also, and I know that it's not the place to talk about it, I would like you to recommend me some full-size (not on-ear) headphones which cost over €150-€200 with great sound quality and noise cancellation, and also good-looking ones (there are some really really ugly haha...).
Thanks for your time :)
