Hey Head-Fi. So I've moved closer to my work to be within walking distance I'm looking for a new pair of mobile cans to use on the trek to and from. Several years back I had a pair of sony DRBT30Q headphones: http://store.sony.com/p/bluetooth-headphones/en/p/DRBT30Q They... were not very good. I loved the retractable cord but that was about it. If I had my phone in my pocket it would cut out on occasion, and the sound quality wasn't as good as I would have liked. I did like the base design, but unfortunately the only thing I've found that they've made since this model is the DR-BT140Q: http://store.sony.com/p/bluetooth-headphones/en/p/DRBT140Q From the specs it looks like a slight improvement on the tech side, but on the audio range it seems about the same as the older pair. Some time now I've been hunting for models of a similar design that are newer but all other makers have about the same specs. At this point I've pretty much given up on the earclip design and am starting to look at over the ear cans. I've repeatedly tried IEMs for the higher quality but in the end they always bug my ears too much. I tried going the wired route with my Grado PS500s: http://gradolabs.com/page_headphones.php?item=d591958ec49fad264e22d3a4ce8777ff but walking with them always ends up with cables getting tangled or loose. At this point I'm debating between two bluetooth cans, the Sony MDR-1RBT: http://store.sony.com/webapp/wcs/stores/servlet/ProductDisplay?catalogId=10551&storeId=10151&langId=-1&productId=8198552921666484169 and the Sennheiser MM 550-X: http://www.sennheiserusa.com/best-bluetooth-stereo-headset-noise-canceling-mm-550-X_504515 I'm split down the middle between the two as both seem to be about the same quality from what I've researched, but I can't make up my mind. I don't care about the noise cancelling on the 550X, but since the price is about the same and I can easily leave the noise cancelling portion off, I am still at an impasse. My phone is the Galaxy Note II so I believe that it will support the Apt-X of the 550X, but honestly I'm highly skeptical that it makes that much of a difference. Any input would be appreciated.
