Frequently Asked Questions - Nika Compact 23905 TRUST
How do I connect the Trust Nika Compact 23905 headphones to my smartphone?
Plug the 3.5 mm audio jack into your smartphone's headphone port. The headphones will work instantly without the need for additional drivers or batteries. For calls, use the integrated microphone and in-line remote.
Are the headphones compatible with my computer?
Yes, these headphones work with PCs, Macs, and laptops that have a 3.5 mm audio jack. For devices with a single combo jack, the headset will support both audio and microphone function. On some computers, you may need to select the headset as the default audio device.
How do I use the in-line microphone for calls?
The in-line remote includes a built-in microphone and a button to answer or end calls. Simply press the button once to accept an incoming call, and press again to end it. When listening to music, the same button can play or pause the track.
What should I do if there is no sound from one side?
First, check that the audio jack is fully inserted into the device. If the issue persists, try connecting to another device to rule out a source problem. Inspect the cable and jack for damage. If the issue remains, the internal wiring may be faulty; contact Trust support for repair.
Can I wear these headphones for long periods?
Yes, the soft padded ear cushions and adjustable padded headband provide comfort for extended use. However, we recommend taking short breaks every hour to avoid listening fatigue and reduce the risk of hearing damage from prolonged volume exposure.
How do I clean and maintain the headphones?
Clean the headphones with a soft, dry cloth. Do not use water, alcohol, or cleaning agents, as these may damage the materials. If necessary, gently remove ear cushion covers for cleaning, ensure they are completely dry before reattaching. Store in a dry place away from direct sunlight.
Are the headphones foldable for travel?
Yes, the foldable design allows the ear cups to rotate inward, making them compact and easy to store in a bag or backpack. The 1.2 m cable is also flexible and can be bundled with a tie or wrapped around the headband.
What is the warranty period?
The Trust Nika Compact 23905 headphones come with a 2-year limited warranty. This covers manufacturing defects and functional failures in normal use. To claim warranty service, keep your receipt and contact the retailer or Trust customer support.
Can I use these headphones with devices that have a USB-C port?
The headphones feature a 3.5 mm jack, so for USB-C-only devices you will need a USB-C to 3.5 mm adapter (not included). With the adapter, you can connect to smartphones, tablets, and laptops that lack a dedicated headphone port.
How do I adjust the headband for a comfortable fit?
Hold the headphones by the headband and extend the adjustable sliders on each side to match your head size. Place the headband over your head and ensure the ear cups fully cover your ears. The sliders have clicks to maintain the selected length.
