JBL Boombox 4 Portable Waterproof Speaker with JBL Pro Sound, 4 Speakers, Black

how do I start. this Bluetooth speaker has great sound I don't listen to rap hip hop dance music I listen to 50 60s 70s 80s 90s rock maybe some alternative rock . . and newer age rock bands! I listen to bands like PinkJ . Floyd The Beatles CCR Boston yes rolling Stones Zeppelin and the list goes on and on phenomenal sound quality highs are crisp the base is low and the mids are just right I don't need bass boost on 1 or 2 or any fancy lights I just want to hear the sound naturally I keep it on the setting it came with sounds perfect recently purchased the Sony ult 7 sounds. goodI but the JBL Beat it hands down I love the build quality it seems pretty rugged and it's not too heavy now volume I never listen to anything over half volume I have a lot of high-end equipment that I refuse. to go over half this Bluetooth speaker it's not bad around 50 to 60%..anything over that will head into harmonic distortion your ears can only hear to so many decibels so it's perfectly fine for me 50 to 60% of the volume,
