I ended up returning this product. It does not work as advertised. 1) It says it is both available AND not available on mobile on different parts of the page (I told multiple people at Logos about this and as of one month later it hasn't changed). It is absolutely not available on mobile, for the record. 2) The product description claims that when you play the audio you can "follow along as each word is highlighted as it is read—just like karaoke" This is 100% false advertising. All that happens is the bouncing circle appears on the first verse of each new chapter. It doesn't even appear to note when a new verse is being read (as is the case with the audio for the ESV), let alone each word! (and yes, I attempted to use the NA27 which is marked as a resource which offers the karaoke feature. Completely untrue!) 3) As of Oct 2018 the same audio can be purchased on Amazon for about $19.95. Given that this Logos product is, essentially, not integrated into Logos software I would recommend saving your money with the cheaper option. Either way you will not be able to follow along "like karaoke." This has been a very frustrating experience with Logos.
