[MENTION=5598721]porscheoscar[/MENTION]: in the link you provided at the end, you have a picture of Seidio DILEX (former ACTIVE) case. You mentioned about $6 ebay holster, so I'm not sure which one you meant. Seidio makes he best holsters, I reviewed all of their cases for Note 2, Note 3, S4, and Nexus 7 (in my signature link). That spring loaded latch is the key to secure fitment, but it always trial'n'error with other than Seidio cases. But it sounds like you are using Spigen case and ebay holster? Can you take a picture of your setup and "write" a link?

Regarding M-100, indeed they are amazing quality and fantastic sound. But I still wouldn't consider them all-around headphones. In the last few months I have been busy reviewing a lot of headphones here on XDA (again, check out my signature link, also a sticky at the top of accessory forum). I looked at V-Moda M-80 and M-100, Audio Technica ATH-M50, Sennheiser MOMENTUM, and Beydynamic COP. M-80 and M-100 are fine-tuned for a specific type of music. For example, they are great for EDM, but when you listen to Avicii latest album "True" with electro-country-progressive flavor and compare it to MOMENTUM - you will realize how much details you are missing in upper mids.

Take a careful look at upper left graph of frequency response of MOMENTUM vs M-100. Do you see what I mean? There is no question about how sweet M-100 sound, but they have "holes" in that flat frequency response in order to boost low frequency and treble. At the current moment M-100 are the most comfortable, coolest looking, and compact for traveling headphones I have tested so far, but their sound is more appropriate for edm, rock/pop, hip-hop/r'n'b/rap, and any synthetic music. Also, while I was streaming movies (for example, watching Homeland through showtime app on my Note 2) - I was raising volume to hear dialog better, bass was raised as well which got in a way of some of the dialog. M-80 has less recessed mids but also less bass; and their on-ear design is not as comfortable. MOMENTUM sound amazing, but they don't have as much bass in comparison to M-100, and lately I started to notice my ears don't feel as comfortable inside of those over-ear pads. They are super light, but a bit of stretch when it comes to earpad fitment; and the main problem they don't fold and have a HUGE carrying case :( ATH-M50 are fantastic for music or any sound production since they have a great balanced of lows, mids, and treble (especially mids hit male/female vocals right in a sweet spot). But they are not as detailed, and also bulky for outside use; not too mention fixed cable without in-line remote/mic. I have seen a lot of mods converting it to removable cable, but I would prefer not to do it. COP had an interesting concept of audio port slider to adjust bass frequency response, but they are SO BULKY - it's just not funny. Also, they tried to copy V-Moda really badly with that metal fork over the earpad and replaceable earphone covers.

Now, I just got B&W P7 for review which so many people raving about. Will see in a day or two what the whole fuss is about. Also, Meelectronics guys sent me their ATLAS headphones. Curious about those as well. I'm on headphone roll right now, so you guys can enjoy some reviews in my upcoming reviews (most of these are loaners sent to me for review purpose).
