Jaybird Freedom (F5) - $199 JB Hi-Fi ($50 off)

Not sure when Australia will see the X3's but possibly these sound just as good???? If not as good a battery life. A few bucks cheaper via Amazon but local bricks and mortar?

Key Features

Micro-Sized Premium Metal Buds
In-ear sport Bluetooth buds have traditionally used all plastic materials, as metal inhibits signal performance. Our innovation in engineering and miniaturization has allowed us to re-invent the manufacturing process, using high-quality injection molded metal parts creating stunning fashionable accents with a premium iconic feel — without affecting signal performance.

The all-metal housing has the added benefit of removing distortion resulting in an incredible sound never before heard in a wireless in-ear bud.

Upgrade Your Ride
That perfect song – sets fire to your soul and liberates your workout which elevates everything you do. From the trails to the streets, Freedom delivers.

Sport + Fashion
Elegant sand-blasted metal accents in vibrant colors become an extension of your personality and style, while also being more rugged than ever, bringing your music to wherever you play.

Secure-Fit
We’ve reinvented audio for sport, with the smallest ever wireless buds and an incredible patented universal over/under secure ear-fit system.

Mysound
Customize your sound to the way you want to hear your music. Your own sound profile is then saved on your Freedom buds no matter what music device they’re paired with or what music service you use. No more complaints of too much or not enough bass – you’re now in control.

8 Hours Play Time
Revolutionary on-the-go charging for truly infinite battery life. 4 hours on the buds + 4 hours on the included charging clip means you never have to stop — you can listen while you charge!
