This is a super duper quick, non-technical comparison based on my personal experience of both headphones.
Bose is more comfortable, lighter & has better noise cancellation. (both passive & active due to its around the ear design) But it does not work if you run out of batteries(AAA), uses a proprietary cable, isn’t wireless and feels more flimsy.
Sony is better in everything else. Better loudness, more louder / punchier bass if needed, better overall sound quality (better mids/highs), Bluetooth wireless (BIG difference), music/call controls, works without batteries (BIG diff), rechargeable via Micro USB cable, works without noise cancellation active, NFC pairing, works with standard 3.5mm audio cable and feels better made (more solid). It’s just not as comfortable (Bose foam is softer & is around the ear) and by design, it isn’t as good in noise cancellation. (it’s quite noticeable)s
Considering comfort is very much subjective, it’s hard to compare. Regardless, Bose is definitely more comfortable still. But due to its lower price, better sound quality, performance and features, Sony MDR-ZX750BN is a clear winner of the two.
I didn’t like the standard case the N9 comes with in the retail packaging as it blocked my earpiece speaker hole and just didn’t make my N9 feel “nice”. So I got the CC-3015 as it was the only genuine Nokia N9 snap-on case you could buy. (I don’t like pouches or full leather cases which cover the screen.)
Anyways, Here are my thoughts and impressions with pictures below:
1. It snaps on tight and there is no way it will come off by accident or dropping etc. There is zero rattle or looseness to it. Although, it does allow about 1mm of slide up or down so that the top of bottom of the N9 can protrude out of the case. However, unless you slide it purposely yourself, it does not slide by itself easily so this is a non-issue in my books.
2. When laid flat on the screen side on to a table, the entire glass front does not touch the desk surface. This means that you can place it face down without a fear of scratching your glass. (yes, Gorilla glass does scratch quite easily still. I have quite a few scratches and chips already on mine)
3. As it has an indented cutout on the sides, it does not intefere with the swipe motion whatsoever. This is my favourite part. It doesn’t interfere with the volume or power button presses also.
4. Is it real leather? Anyways, it feels fairly classy and even has real thread stitching which adds some extra touch. It does not feel like it will rip easily or get loose/stretched. It’s very tightly and near seamlessly glued on to the hard case itself. It’s not as soft as I expected. Seems like a very thin leather. Not a minus. Just saying. I actually don’t mind the squircle design either. Although, I would have preferred white instead of pink squircles on my black version. =P
5. I would have preferred the hole for the camera and the LED flash to be bigger. Although it doesn’t interfere with the camera too much, there is always a potential of extra light reflections from the outer edge of the camera hole. Also, the LED light output would be somewhat affected as well due to it slightly blocking the outer spill light from reaching wider angles. I haven’t tested this yet and maybe it’s not an issue in real life but I thought I would mention this anyways.
6. It improves the grip-ability of the N9 also significantly. It no longer feels like it’s going to slip out of my hand while holding it. No way. I love how this case gives you that extra tactile feedback while holding the phone. The four protruding corners make it feel much more secure in my hand. This is a huge plus for me.
Overall, I really like it. It’s definitely better than the standard silicon/rubber case it comes with in terms of looks and it also protects the glass front on flat surfaces. I would have hoped Nokia made the case more like the Nokia N8 case (CC-3000) which to me feels better and is also lighter and thinner. But this CC-3015 case is still worth the money for those who wants a genuine case, don’t mind the colorful design and want a nice snap-on hard case that feels great in hand.
Anyways, I recommend this case. It’s staying on my N9 that’s for sure. =)
