I used a Speck Candyshell for a year on iPhone 6, and my only gripe (and this isn't the case's fault) is that dust tended to get into the lightning and headphone port because I carry the phone in my pocket. Otherwise, a fantastic case. I'm looking for a non-bulky case with port covers. I've used the Switcheasy Numbers case with my 5s (another great and cheap case), but want something with a bit more protection. I'm trying the Otterbox Commuter, but am not that happy with it, so the search continues. Big cases like the Defender are out, as are cases requiring a headphone adaptor (Lifeproof). Any suggestions?
