JBL Tune 780NC: 76h battery… but it needs battery to work WIRED?!

Impressions

Seriously, I thought I’d be able to plug it into USB, charge it and still use Bluetooth at the same time. It didn’t even need to play audio directly over USB (although they could’ve added that too). But nope: battery dies, the headphones turn into a paperweight.

“Oh, but 5 minutes of charging gives you 5 hours of use...”

FUCK THAT! What a piece of crap!

I was already disappointed when I tried the spatial sound. What the fuck kind of garbage “feature” is this? It just adds some shitty echo and reverb and makes everything sound like crap. It doesn’t even have an accelerometer to at least try to give you some sense of spatial audio, or if it does, it sure as hell doesn’t work... It literally does nothing except make the audio sound worse!

Another thing that pisses me off is the advertised 76 hours of battery life. No, man... I’m actually pissed. 76 hours with ANC turned off (which is understandable) and BLUETOOTH.

BRO, THE HEADPHONES NEED BATTERY TO WORK WITH THE FUCKING AUDIO CABLE...

Nah, man. You’ve gotta be kidding me... I’m done...

I miss my Edifier W820NB. It broke because the build quality was kinda shitty, but the sound was perfect, the 40-hour battery lasted me the whole week, and when it died I could just plug it into USB and, as a bonus, get Hi-Fi audio while it charged...

Also kinda regret not taking a chance on the QCY H3S. It was like 100 reais cheaper...

Sorry for the rant!
