  • JBL Professional Audio Sound with PureBass performance
    It’s no trade secret we’ve created the world’s most legendary loudspeakers. Artists from the Beatles to Maroon 5 have used JBL equipment to create some of their most historic recordings. So it should come as no surprise we’ve taken Pro-Audio sound to new highs – and depths – of power and portability in our Synchros Series. Introducing JBL Professional Audio Sound with PureBass performance. One listen to our S300 – and the phrase “clarity of sound” will never sound the same. PureBass performance is much more than a tag-line, it’s a philosophy. Focusing on the full audio spectrum, not just the low end, the headphones deliver a balanced audio experience with amazing clarity, and deep powerful bass; producing clear separation of notes, avoiding the boominess and muddy sound found in other popular headphones.
  • Collapsible design
    When it comes to convenience, the perfect pair of headphones should satisfy in all departments – whether in wearing them out on the town or in storing them at home. The S300 headphones incorporate fold-up, 3-D flexibility into their design that lets you fold them, collapse them, and store them neatly away – ready for whatever adventure befalls you.
  • Detachable cable with Apple 3-button mic/remote cable
    On-the-go compatibility with an iPhone or other popular smartphone isn’t just a nicety these days in a premium headphone – it’s what you need. The JBL S300 is built with that principle in mind, coming in two possible configurations: one using an Apple 3-button mic/remote cable and one using a universal 1-button mic/remote cable to keep you’re listening fun and flexible. Either option synchs easily with your S300, allowing you the freedom to enjoy your music or easily take calls without missing a beat

Synchros S300i is rated 4.6 out of 5 by 5.
Rated 4 out of 5 by from I'm satisfied! After much searching, I am satisfied that these are excellent headphones. Are there better headphones to be had? If so, I have not heard them, and I have tried many. The S300i have that characteristic JBL sound: tight, but not overwhelming bass; a full, rich, and balanced sound; and a clarity that you can't find elsewhere. Would over ear headphones be more comfortable? Perhaps, but these fit the bill easily. My only question is what would the S500 and S700 series sound like? Can they be that much better than the S300i?

Rated 4 out of 5 by from Actually 4.5 stars The sound is good, for the first time i can hear all the instruments, i LOVE the focals, but isn't the treble is too much? Would be better if it's really balanced. And the pure bass is AWESOME, the bass is balanced, but below 30 hz i can't really feel it. It feels high quality, but i got this with the left one is a little bit loose, but overall it's really durable. I like the design did not use wires to connect between drivers and looks cool with those leathers, and with many nice touches too. Once you take one of these things, you will never want to take these off, it's comfortable. But the noise isolation is so-so, i still can hear background noises. With high durability, clear sounding drivers, looking awesome, and it's very comfortable. This is no brainer price. For 150 bucks? This is awesome
