Oppo's enco x2. Oppo's sound really, really good. Great soundstage but not quite the bass (but good). They won't link up to my laptop for whatever reason so I only use them to listen to music. Oppo's are my go to for music but they other are not far behind. I haven't had the one plus long enough to give my judgement but they are great too. I really like the Liberty 4 and soundcores app is easy to use. I use them mostly for watching TV or sometimes listen to music. I've had the Denon's and they are great but not worth the extra imo.
His reviews seem to be spot on for me but everyone hears different and has different likes. Btw, my wife liked my Oppos so much she bought some. Just a really good smooth sound. If you can't get it on ebay go to Aliexpress. I've mostly had good luck with Ali but I did have a problem with a fake one time
