Do WR700 wireless headphones work with all digital music players?
Yes, they will work with any digital player that has a 3.5mm (1/8”) audio jack. Note: Because WR700s do not include an in-line mic or controls they are not recommended for use with the third-generation iPod shuffle.
How do I sync the headphones to the transmitter?
1) Make sure the volume setting on the audio player is low, then insert transmitter into a suitable headphone jack, using the extension cable, if needed. Press the power button. The LED will then start flashing, indicating that is in Search Mode. 2) Press and hold the power button on the right earpiece until red LED on button flashes. 3) Once the headphones detect the transmitter the LEDs will flash in unison.
How many headphones can be synced with a single transmitter?
Our technology enables up to 4 users to share the listening experience from the same audio source.
How many batteries are required and how long do they last?
Four AAA batteries are needed and included with the WR700s. Two in the headphones and two in the transmitter. When listening at average volumes, the batteries will last 30-40 hours.
When I plug my guitar into an amplifier or PC and use the TDK WR700 headphones to monitor the guitar's sound, there is a noticeable delay which makes playing very difficult.
There is a delay of 0.125 seconds during transmission from the audio source to the wireless headphones. The delay is required to give the headphones an opportunity to request a retransmission of data or to select a new frequency channel when interference is detected, greatly improving the quality and reliability of the audio signal. Unfortunately, when playing a musical instrument the time delay is unexpected, making it very difficult to simultaneously play and listen. Professional wireless in-ear monitors and instrument pickup systems are designed for minimal delay using analog VHF radios.
My WR700 wireless headphones try to turn on, but won't play music. Are the batteries dead?
As the batteries drain, the WR700 headphones will detect the low voltage and light the LED to indicate that the batteries should be replaced. The headphones will continue to operate for a while longer. When the batteries are completely discharged, the WR700 headphones will turn on, but then immediately shut off. Once this happens, the headphones are no longer operational and the batteries should be replaced.
