Best Mini Speaker with iPhone for Outdoors?

[microscopic.truth]

Here's the criteria:
- a full battery life of around 1.5 hr for my walks etc
- must be louder and better than my built-in iPhone speaker
- can be plug or bluetooth (as long as reliable and long enough battery life)
- size should be as small as possible - not more than my iPhone SE for example

Here's one example just to give you and idea of what I have in mind - but it's not good quality and I don't want a fixed plug it's a crap design:

Many of those types of speakers around

Bose soundlink micro, JBL Clip, JBL Go (does not really have a clip or arm mount), bunch of generic brand things on Amazon https://www.amazon.com/dp/B07LBFMT55/ref=sspa_dk_detail_5?psc=1 This Doss may be good https://www.amazon.com/dp/B07HHNJCZL/ref=sspa_dk_detail_0?psc=1 I have a Doss speaker in larger size.

Why not use headphones? Will sound better and nothing extra to carry.

My first thought exactly. For walking? and carry that weight? Outdoor speakers tend to be bad, they got nothing to bounce their sound off.

If u just absolutely cannot wear earphones, don't quote me but my brain is telling me stereo speakers worn as a necklace and the drivers sit over your chest and fires up to your ears, just don't ask me where I saw them.
