PlayStation 5 is a beast
Style: PS5 Disc, Configuration: Console only
I never thought I would be a gamer at 62yrs old but after playing the PlayStation 5 at my cousins home & seeing the great graphics ,the choice of all the different types of games available for anyone's & everyone's interest, I had to have one. Are they expensive? Yeppers! But, they are well worth it as this will last for many many years, even if I wind up in a retirement home, this will come with me & I will never be bored. I might drive someone else "Batty" ( if I have a room mate he wont be there for long but thems the breaks kid!) This was purchased at an absolute excellent price & I am very thankful. Delivery was fast & on time. Thank you

Wish I invested in the Playstation 5 sooner
Style: PS5 Disc, Configuration: Console only
Before buying this I had the Switch 2 and Xbox Series X; however, after buying the Playstation 5 I am blown away right out of the box. The Series X and PS5 are both 4K next generation systems, and though the Series X has the 12 teraflops graphics processing the PS5 looked way batter on my 4K TV. I also like the added functionality of the controller adding to the gaming experience with the touch pad, microphone, and gyroscopic motion control. The console is even turns on automatically by changing TV to the system's HDMI input and puts the TV into gaming mode. That is something the Series X and Switch 2 of course never have done. One down side is the system is notorious for not supporting audio cds which going back the original Playstation in 1994 the brand was always able to support. Plus if you get a cd stuck in the disk drive like what I did recently Sony made it possible to remove the disk without destroying you console in a few easy to follow steps. That saves gamers alot of money in repairs if something like that were to ever occur which is a well thought out solution. With former Xbox exclusives moving to the Playstation 5 I highly recommend adding this system to your collection.

Quality Thumping Boombox
Color: Black, Color: Black
I've been a longtime user of JBL products, but the Boombox has been my favorite speaker in their entire lineup. The built in handle, waterproof design, and fantastic battery life are what drew me to it in the first place. I owned the original Boombox for nearly 8 years. It survived dozens of camping trips in extreme heat, and was tested by FL beach trips, one of which ended in a violent rainstorm. It never failed me and could hold up to any abuse, which is why I have no problems recommending their Boombox lineup to anyone.
My excitement for the Boombox 4 grew when I found out it would use an easily replaceable battery, simply by popping off the bottom cover. I had to replace the internal battery of my BB1 after 7.5 years, and it was a terrible experience that took around two hours, and was very frustrating at times. I told myself I would never buy another Bluetooth speaker that didn't have a hot-swap style battery compartment. I'm happy to see that the new speaker lineup does this.
SPECS
The new JBL Boombox 4 has significantly more power than the original model from 8 years ago. We're talking a jump from 40 watts to 200 RMS watts on battery power. That, combined with the larger drivers let me know that I was in for quite an upgrade. If you already have the 3rd gen BB3, I would think this wouldn't be a significant upgrade for you, but coming from the OG BB1 it most certainly was for me! The ports on the rear flip cover are power and USB Type C.
APPEARANCE
After unboxing the new Boombox 4 I could tell it was a bit larger than the old Boombox 1, but not by much. I'm happy to see JBL go back to a handle that appears to be a part of the speaker, instead of looking like it was thrown on as an add-on, like that of the Boombox 3's handle. It's also comfortable to hold, and the weight distribution of this speaker is spot-on. I can't tell that this new speaker is 1.5 pounds heavier than the BB1. Overall it's a very good looking speaker. The pictures don't do it much justice. You need to see it in person to really appreciate the craftsmanship.
INDOOR LISTENING
My initial listening experience with the new BB4 was ear-to-ear grin worthy. I immediately realized this upgrade was legit! There's so much more lower end grunt. While playing indoors at lower volumes, I found that for certain music genres I really appreciated the low-end bass boost mode. It provides the thump you crave, even at low levels. As you raise the volume up to anything over half, I find the bass boost unnecessary, and perhaps even a bit overpowering. That's likely subjective to each persons personal tastes, as well as music genres. It's nice to have the option to use it when you want it.
OUTDOOR LISTENING
My OG BB1 was my favorite go-to speaker for outdoor Bluetooth music sessions, and this one excels even more at that. The BB4 has significantly more power on offer, so it's easier to fill any space with fantastic sounding music. With our modest sized corner lot, I find that keeping its volume around the 50% point is plenty to fill our yard with great sound, while not being distracting to any neighbors who may be around outdoors. What impressed me most with the new speaker is how much further and clearer both the highs and low frequencies come through. With the BB1, once I walked away more than 20 feet the bass really fell off and wasn't too noticeable, but with the BB4 I can still hear the low notes from that distance. I'm truly impressed at what the BB4 can do as an outdoor speaker. To respect my neighbors, I didn't run the Boombox 4 at maximum output, but for the brief time I had it up around 80% it was obvious that this speaker is plenty loud for most people.
AURACAST
Next I paired the Boombox 4 with my PartyBox 520, using Auracast. I turned on both speakers, started playing music from one, then hit the Auracast button on each. Within 5-8 seconds they paired up and were in sync with each other. Obviously pairing a speaker like the Boombox 4 along with a much larger one like the Partybox 520 is going to create a situation where you mostly hear the larger speaker. This leads me to the decision that the best way to utilize a setup like this is to run one indoors and the other outside. For a nice sized party, the Boombox would serve well indoors and the PartyBox would be perfect outside.
CONS
If I had to knock JBL for anything with the new BB4, it would be their decision to omit the 3.5mm aux port. This was a feature all the previous models had. I know there's a USB Type C port for lossless audio playback, but it doesn't work with a Type C to 3.5mm aux adapter. I enjoy projector movie and game nights, and I used my BB1 for the audio when viewing content with the projector by way of a simple aux cable.
I did a bit of research and discovered that my Google Chromecast has Bluetooth audio playback available, but not the Roku streaming stick that I've always used for the projector. I was able to connect the Boombox 4 to my Chromecast and use it to play the audio, so I'm thankful that works! Still would have loved a 3.5mm aux port.
SUMMARY
JBL continues to impress with their newer lineup of speakers. As bittersweet as it was to let it go, I'm happy to be rid of the Boombox 1, as the Boombox 4 is an amazing upgrade in nearly every way. I won't have to worry about complex battery swaps in the future, which is probably the main reason I went for the upgrade. I'm happy with the extra power this speaker puts out. For anyone looking for an all-purpose, outdoor Bluetooth speaker, this is the one! No need to worry about water or dust interrupting your music sessions. Stop thinking about buying a Boombox 4 and just pull the trigger!

Perfection.
Color: Black
HANDS DOWN THE BEST BLUETOOTH SPEAKER ON THE MARKET. I have bought pretty much every BT speaker on the market (obsessed). I'm an audiophile and my main system is worth 10s of thousands. I had multiple jbls, bose, and a whole slew of different brands i dont care to list. I gave away most of them to justify buying new toys (my friends love it lol). I am not giving this thing away EVER. All my previous complaints have been addressed. Replaceable battery, stable base, lighter, smaller and double the output. For indoors i use a custom EQ to tame the bass. Because it is RIDICULOUS (alot of overhead!). I crank up the treble to sharpen it up and I find that 30% volume will fill most indoor spaces with excellent, long playtime and sharp music while barely trying! It has plenty of overhead to deliver excellent volume and presence for the beach and any outdoor event up to 60 people. This is the perfect setup. Need more coverage? order a second one for stereo (i will). This is the end game Bluetooth speaker. Everything else is a mere shadow of this beast regardless of price. JBL knocked this out of the park. My search has ended.

Excellent upgrade from Boombox 3
Color: Black
This bluetooth speaker packs a good punch without flooding the overall soundscape with excessive bass rattle. Great sound at good value.
