Lynxsonic 4:33 User manual

Yaaaaaaaaaay!!! You are now the (hopefully) proud owner of a pair of
"first edition" LYNXSONIC 4:33 headphones. Thank you for supporting this
project and apologies that the delivery took longer than expected! We've
had a number of teething problems to solve which delayed things but we
would rather take a bit longer to get them right than rush the headphones
out at lower quality. Y
This booklet describes the packed functionality of the 4:33...there are
many awesome features so we've tried to make the user interface as
intuitive as possible whilst still only having a few buttons... on top of
everything else we really love using the "free talk" button... check it out!
The LYNXSONIC team wishes you many hours of "quiet enjoyment" !!!

Q&A
1) What is ANC?
ANC stands for “active noise cancellation” - this feature is designed to
eliminate ambient noise in your environment allowing you to enjoy your
music without distraction while working, traveling or simply relaxing. It is
most effective at reducing LOW frequency noises such as those from an
airplane engine or a large crowd ( frequency from 20HZ-800HZ).
2) Why do I still hear certain noises with ANC on?
The ANC feature is best at reducing constant/steady LOW frequency
sounds. Sudden, irregular noises, such as shouting or car horns, are not
as effectively canceled out.
3) Is LYNXSONIC 4:33’s “AMBIENT Mode” a kind of hearing aid?
No, LYNXSONIC 4:33’s “AMBIENT Mode” is not a hearing aid. LYNXSONIC
4:33 is designed to improve the ability of the general population to hear
conversationsin noisy environments.
4) Why am I still suffering an audio delay?
To achieve Low Latency, your Bluetooth transmitter has also to be aptX
LL supported. If your Bluetooth transmitter does not support aptX LL you
will have a latency between sound and image.
5) Can I still use my headphone if the battery has run out?

Yes, when the battery is low, you can use the 3.5mm audio cable to
stream the music, just like the wired headphones.
Note: The touch on the headphones will not work at this connection.
6) How to charge?
There are two ways to charge LYNXSONIC 4:33:
A. (Wired) You can charge LYNXSONIC 4:33 via the supplied Type-C
charging cable to your own USB chargers.
B. (Wireless only for Deluxe edition) You can charge LYNXSONIC 4:33
via wireless charger. Put the left earcup on to the wireless charger.
While in charge, the LED indicator on right side will show RED, and it will
disappear when it’s fullycharged.
7) How to connect with two mobile phones?
Pairing with two mobile phones.
A. [Connect the FIRST phone] From off, press and hold the power
button for 5 seconds until the LED indicator blinks blue and red
alternately, then pair with the first phone as pernormal.
B. [Connect the SECOND phone] Turn it off, then press and hold

C. [Search and connect the headphones on the FIRST phone

time. Simply make sure both of your devices and LYNXSONIC 4:33 will
