Lightweight Retro Bluetooth Speaker with TF USB FM Aux for Travel

Honestly, no. But I use mine indoors - on my desk, in my bedroom, or in the kitchen. For those spaces, it's perfect. Most waterproof speakers seal up the ports and sacrifice sound quality. This one doesn't, and I can hear the difference.

Yeah, I've taken mine on a few trips already. The 1200mAh battery is small enough for carry-on. Just toss it in your bag and you're good. Security never even asks about it.

Yes, it surprised me. The 40mm driver with dual diaphragms and 2.1 channel stereo actually gives you punchy bass and clear vocals. It's not a big system, but for its size, it sounds way bigger than it looks.

Around 5 to 6 hours of mixed use at medium volume. I charge it every couple of days. It's not all-day battery, but for daily listening it's more than enough. I never worry about it dying mid-session.

Yes, if your TV has Bluetooth or AUX. I use mine with my laptop for shows and movies - no delay, no lip-sync issues. Works like a charm.
