Question 1

How many strands?

Accepted Answer

The number of strands is meaningless as to the quality of the cable. The ONLY reason for using stranded wire is that it is much more flexible than solid wire.

Question 2

Does anyone know the diameter of the whole cable shield included? Is 3/8"?

Accepted Answer

Product received on 5/26/2021 was 7.5 mm or ~9/32"

Question 3

i realize this states for in wall but does not specify if UL approved, is it actually UL approved so it will pass building code for in wall use?

Accepted Answer

Attached is an excerpt from UL.com guide card for AVLV2 category code.  It describes how certified wire should be marked.  You can check for UL certification at UL.com on-line certification directory if you know manufacturer name or file number.  The seller may be able to get you this information for proof of certification.

REQUIREMENTS

The basic standard used to investigate products in this category is ANSI/UL 758, "Appliance Wiring Material." In addition, IEC TS 60695-11-21, "Fire Hazard Testing - Part 11-21: Test Flames - 500 W Vertical Flame Test Method for Tubular Polymeric Materials," may also be used.

UL MARKING
Components Recognized under UL's Component Recognition Program are identified by markings consisting of the Recognition Mark of UL (shown below) on the attached tag, the reel, or the smallest unit container in which the product is packaged.

In addition to the above tag, reel or container marking, the Recognized Component Mark  may optionally be surface printed on the appliance wiring material. When used, the product name "Appliance Wiring Material" (or "AWM") will also be surface printed adjacent to the Recognized Component Mark , followed by the Recognized company's identification and/or file number. If the Recognized company's file number is an element of the surface printing, the Recognized Component Mark  is required to also be surface printed.

The Listing or Classification Mark of UL is not authorized for use on, or in connection with, Recognized Components. Only those components that actually bear the "Marking" should be considered as being covered under the Component Recognition Program.

Question 4

Can is be used outside? Direct 14/4 direct-burial speaker wire

Accepted Answer

The wire that I purchased was 14/2 and was not rated for direct-burial or in-wall use.   You should look for wire specified for that application.  This would not be suitable for that, though I would be comfortable hanging/stringing it along under eaves or a patio roof, so long as it was reasonably sheltered.
