JBL Go 3 - Portable Mini Bluetooth Speaker, big audio and punchy bass, IP67 waterproof and dustproof, 5 hours of playtime, speaker for home, outdoor and travel (Pink)

Instead of a portable sound machine I have this, I just play white noise off of Apple Music. Battery life is great, just as portable as a keychain sound machine, and can use for myself too if needed. Really great product
