I bought JBL T150A few days ago and after I unwrapped the package I tested jbl and you don't believe me when I listen to a song I got shocked yes because it's base was amazing and sound quality is very good but sometimes sounds become too loud to hear at full volume.
So if you are listening to a low base song with loud sound then you have to lower the volume to feel the goodness. I liked it most of its bass and as all the latest songs are of heavy bass it makes listening better in jbl. Its better then sony, philips, even samsung because i've tested all but stopped at jbl and its quality is pretty good and it is durable also and you can use it for long time without any problem.
