JBL Flip 7 Portable Speaker, 35W, Bluetooth, Auracast, 16-hour battery life, IP68, Red Bold JBL Pro sound with AI Sound Boost We've beefed up the bass and tweaked the tweeter. The result? Stronger, clearer bass even at maximum volume and crisper highs thanks to a clever new tweeter dome design, adding more depth to the speaker's sound. We've also added our new proprietary technology, AI Sound Boost, which analyzes music in real time to deliver maximum acoustic performance with less distortion. It's like a little audio genius in every Flip 7. So now we can give you better sound, without the extra pounds. Same size, more power. Up to 16 hours of playtime Keep the mood alive for 14 hours on a single charge - and when we really need to squeeze some extra energy from our jubilee or another dance with our sweetheart, we can get an extra 2 hours with Playtime Boost. Multi-speaker Connection via Auracast™ Wouldn't it be great to share the vibes with our tribe? Now we can. With Auracast™, we can effortlessly stereo pair two Flip 7 speakers for a wider soundstage, and we can connect multiple Auracast™-compatible JBL speakers to cover more ground with the same playlist. Water, Dust and Drop Resistant Have you ever dropped your speaker, rolled it down a dusty hill and dropped it in a lake? No? Well, believe it or not, it happens. So we built the JBL Flip 7 to be as durable as possible. In addition to our legendary water and dust resistant design (IP68*, industry leading, BTW), we also made sure that if you drop it from 1 meter onto your concrete floor, it will still kick ass. But please, don’t drop your speaker just for show. Throw a party instead. *Based on lab test conditions for submersion in up to 1.5 meters of fresh water for up to 30 minutes. PushLock System with Interchangeable Accessories Grab it. Strap it. Slap it. Now we can carry our sound our way with the new Pushlock Interchangeable Accessory System. All this power at the push of a button - Wrist strap and carabiner included in the box. Lossless Audio Playback When music goes lossless, it gets even better. For true audio enthusiasts, we’ve made lossless audio possible by connecting to your laptop or other audio device via our USB-C port. But of course, you need a compatible lossless audio source to make it work (requires compatible lossless audio content from supported apps/services). JBL Portable App It's an app. We've all used them, and they can be very useful. The JBL Portable app gives you access to support, updates, and customizable audio controls - so you can get the right sound for your mood at any time.
