Delivery was great and was delivered well packaged and with care. Prior to purchasing this i had tested a few portable speakers including a smaller version to this at currys to get an idea. Due to being a better value i decided to go ahead and purchase of Amazon. The sound is very bassy and loud. Battery life is great depending on use of course but I do not have to charge this that often. This gets more power and louder when plugged into a wall socket. For some reason it adds more wattage by doing that. Overall the sound quality is excellent and the bass would shake your room but in a smooth way rather than like a subwoofer. The mids are clear and the highs are very decent. I tried a sony srsxg500 and a marshall acton against this and felt this gave me the overall sound quality i was after. The sony sounded clear but lacked in overall bass and punchiness. The marshall had great sound at low levels but again at higher volumes it ran out of steam and the box enclosure would shake and rattle which put me off. Marshall acton was a great speaker overall as everyone has different taste. Those that hear guiter based songs should try a marshall. This JBL Xtreme plays all songs very clearly and with punchiness. They also own Harmon Kardon or vice versa used in Bmw vehicles. I also tried the xtreme against the flip 6 whilst in store. The flip 6 was pretty decent and if budget is an issue then go for flip 6 as it is pretty decent for the price. The xtreme is for those that want more deeper bass, louder and overall a fuller sound. I would defo buy this again in compared to the choices out there as this for me is by far the best speaker hands down against the competition. I recommend you head to currys to hear it in person to get an idea but as a blind buy you will not be dissapointed with this. Comes with a wall charger and a something to hook the speaker onto so you can carry it around. Buy without hesitation, no matter what genre you like this will play it well. Amongst the ones i tested this was worth tge price. The speaker is waterpoof and dust proof so for those who have pool partys its perfect for that. Battery life is fantastic i have not yet had to charge it and its been 2 weeks so cannot comment on how long it takes to charge. The charger is usb c. Excellent speaker and great price!!!
