this is more speaker for less money than the JBL Boombox 3 deal. but the Sony's are much less portable.
$349 is the lowest price I have seen so far for the XP500. https://au.camelcamelcamel.com/product/B09YXH4DBS
Currently $444~449 everywhere else.
XP700 has been $399 before in July. https://au.camelcamelcamel.com/product/B09YXH5L32
Sony's biggest models are battery powered (same can't be said for the Large JBL Party speakers). they also support LDAC and have a single mic input for karaoke.
in a Sony vs Soundbokz vs JBL comparison. the Sony and JBL quite obviously had deep extending bass, while the Soundbokz (biggest one they have) lacked deep bass. I think Soundbokz get's louder though so that's just how it's designed. Edit: Soundbokz also has swappable battery packs and better battery life than the JBL and Sony.
I recommend the XP500. why? when you get to this kind of size, the less weight the better. XP500 is 11kg, while XP700 is 17kg.
the smaller XP500 also not only has the handle, but it has built in wheels making it easier to move around if you need to. -google images was showing me the wrong image.
XP700 has an extra 5 hours battery estimate over the XP500. both are IPX4 splash proof.
XP500 Speaker size: Tweeter 5cm x 2, woofer 14cm (5.5") x 2
XP700 Speaker size: Tweeter front 6cm x 3 rear 5cm x 1, woofer 17cm (6.7") x 2
*battery life depends on volume level.
I want one, but don't need one.
