Big on sound – precise in design

Now you can have your sonic revolution and carry it easily too. The new JBL Synchros S300 breaks from traditional headphone design. Lightweight, yet durable, with a steel headband and leather ear cushions, the S300 is comfortable for hours of listening. Modeled after the same JBL sound systems used in the world’s most prestigious clubs, the S300 delivers a balanced audio experience with amazing clarity and deep, powerful bass. The earcups rotate and fold in for simple, compact storage. Available in 4 colors, the S300 is compatible with both iOS and other Smartphones.

We meant it when we said we’d build a revolutionary line of stylish headphones. For those who know authentic elegance when they see it and hear it – meet our new JBL S300 Headphone. Its precision boldness and rugged good looks come fused together by a steel headband that’s both lightweight and durable. Its premium leather ear cushions provide your ears with more than just perfect listening. For the fearless interloper within us all, the JBL S300 demands seeing - as much as hearing – to be believed. Score another instant JBL classic.
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.
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.
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
