Review on JBL Flip 4 Grey: Waterproof Portable Bluetooth Speaker for On-the-Go Music by Rebecca Harris

I compared 3 similar portable speakers (same price around $100 each): JBL Flip 4 - best sound quality of 3 (amazing quality - very similar to Bose Soundlink). Mini) - No noticeable crackling at max volume with high treble in music - Strongest/deepest bass (my desk shook at max volume) - Very loud max volumeUltimate Ears WONDERBOOM - Smaller than JBL 4 but bigger than Bose Micro - Crackle at max volume for some songs with high treble (didn't expect that) - Bass not that strong (very weak bass) - Very loud max volume (similar to JBL 4) Bose SoundLink Micro Bluetooth - Smallest of 3 - Max sound was 75% sound JBL 4 /Ultimate Ears - Sound "muffled" and fuzzy (quality nowhere near Bose Soundlink Mini) - Open charging slot (is it really waterproof?) similar to Bose Soundlink Mini but waterproof!) and Ultimate Ears for portability (75% the size of the JBL 4). The Bose Micro, while very small, had very poor sound quality for the price (most disappointing).
