Have been using these for 5 - 6 months. I am disappointed with its battery backup. If I play it at full volume, the battery lasts for just 1 and a 1/2 hours. at 60 to 70% volume it lasts around 3 hours. Considering the brand is Philips, I expected a better battery output. One area where the speakers perform well is the sound quality and loudness. These are significantly loud for a speaker of that size.If you don’t mind the battery backup, then you should opt for these
