Accessories help for my replacement note 7

[EternalSeeker]

Dear LTT forum,

I have decided to create a thread with all my questions (I will include a TLDR as well). 

TLDR: Looking for BT headphone, smartwatch and screen protectors that work with spigen slim armor case.

--------------------------------------------------------------------------------------------------------
Question 1: Looking for a Bluetooth headphone for primarily thenote 7 but can be used for other devices?

So as the question states, I am looking into bt headphones preferably on ear. I currently use a AudioTechnica ATH MSR7 with my pc at home but its to heavy to carry outside. Most wired headphones stop working because of damaged cable at the gym as well. So I am looking for a bt headphone with good audio signature (something like the audio technica i have), is lightweight, good build quality, great battery (with wired 3.5mm support), has built in microphone and aren't to flashy and won't smell bad due to sweat and will stay on my head during weight training and cardio. I have looked at some, boss qc 35 are amazing and feel great but to expensive, sony H'ear are too flimsy and plastic for my taste and don't have clear low ends, beats solo 2 sounded good but they are beats so I don't know. I haven't found a store with the Jabra moves so I don't know. Any help will be appreciated!

Question 2: Looking to get a smart watch for my note 7?

So I am looking for a good smart watch to replace my sieko watch. Something with a clean look, scratch resistant, maybe even water/dust resistance, has fitness features, built in gps, allow me to control most of my apps, allow me to reply to text/email and make calls, etc. I am really loving the gear s3 frontier, should I wait for it?

Question 3: When my replacement comes should I use my clearplex warrenty to get another screen protector and back protection or get a new protector and skin to go along with mycase?

So I currently have a black onyx note 7 (which I will replace with another onyx note 7). I have the spigen slim armor case that is gun metal black. I love it and will be using it. So I currently have a clearplex hd screen protector and I love its feel, clarity and sensitivity compatibility with my phone. It works well and I don't loose any screen sensitivity or clarity. I was thinking of getting this screen protector applied to my new note 7 (when it comes) and also cover my phone back and sides to protect it from scratches since its already shatter resistant (due to gorilla glass 5) and my tpu layer case. The issue is that in the case it causes the screen to peel a bit even after 24 hour cure time (picture of my screen protector at the moment "imgur.com/a/gEMCW") so I am conflicted. I think it maybe because the screen goes edge to edge (which in theory should help scratch protection) so to people who have cases like thespigen slim armor or have used protectors like clearplex, what should I do? Is it worth switching protectors? is it worth to get skins to protect the back of the phone?

Question 3: Should i invest in wireless charging and extra type-c cable and a battery bank or just stick to extra cables and battery bank?
