Products Details

Here is what some music professionals mentioned about SoundFlux?:

Another masterpiece from our industrial design team who have won several awards over the years, to name a few: the?iF Award, Red Dot Award and IDEA Award.?SoundFlux will not disappoint you with its high-end look and finish, which separate itself from a numbers of plastic toy-alike competitors.

Our Dual-Driver True Wireless Stereo Headphones provide a much wider dynamic range than most single driver headphones currently available on the market. The two professional quality 6mm dynamic drivers work in unison?with noise cancellation technology to cover a wide range while?offering a clear and?pure sound experience.

  • Dual Driver
    • One focuses on creating a solid foundation - bass
    • The other focuses on keeping the high end accurate and clear,?mid and highs - treble
  • Professional Audio DSP
  • Lossless Codec
  • Dual-Driver Ambient Noise Cancellation
  • Software Optimization

Regular headphones have a limited range of frequency response since their single driver can only cover part of a?human's hearing range. They either perform average in both bass range and treble range, or are tuned to cover one and leave the other poorly compromised.?

Powered by a dual driver audio system, SoundFlux? covers both bass range and treble range naturally with the two professional grade drivers.

Adjust EQ from headphone

Three preset EQ settings to choose from:

  • Naturally Balanced
  • Vocal
  • Enhanced Bass

SoundPass? Mode, when enabled, allows you to be aware of your surroundings and engage with the environment without pausing your music.

A simple triple-press of the multi-function button will?activate SoundPass? mode, and you can talk to people without pausing music.

And yield traffic while jogging.

Frequently Asked Questions

How can SoundFlux activate Siri?

Press and hold the button on either side for 2 seconds while idling. If you are listening to music, you need to pause the music first.

How can I tell the battery level of charging case?

When the case is being charged, the white LED flashes to show the battery level. When the case charges headphones, the LED also flashes. In other circumstances, the LED keeps off. Please check with the manual regarding battery level indication.

What codec is supported?

For iOS devices which default is AAC, such as iPhone, iPod and iPad, SoundFlux streams music based on AAC codec. It can be traced in the Bluetooth log (codec code '2'=AAC while '0'=SBC). For Android, the AAC codec was not default but needs to be forced. Our engineering team are analyzing to see if there is any improvement can be made.

Does SoundFlux work with my laptop?

SoundFlux works with all MAC, Windows and Android. For most of the time you just need to connect them to your laptop. For some laptops, you might need to change the 'output device' to Bluetooth (SoundFlux) since some computers does not switch automatically.

Why the battery life is shorter than targeted?

Previous engineering samples were tested to have 4.5 hours of battery life, with Bluetooth module consuming below 10mA. However the beta version software had many bugs and couldn't catch shipping. The module manufacturer fixed them with a stable version software but not fully optimized in power saving (around 1.5 times of beta version). We just found out and now work with them to find a possible improvement for a lower power stable version software and software solution for over the air updates.

How to compare the sound quality of SoundFlux to other headphones?

As true wireless stereo headphone, we compare SoundFlux with its peers, since true wireless headphone is a very different form factor than wired Bluetooth (two earpieces connected by cord) or even wired headphones and requires different technology. SoundFlux has better sound quality than most true wireless headphones in market at same or even higher price point.
