Avantree HT4186 Neckband Earphone Set with Bluetooth Transmitter for TVs with Optical Digital AUX Plug and No Audio Wireless Earphones for TV

【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. [TV Compatibility] HT4186 is compatible with TVs with built-in optical (TOSLINK), AUX (3.5mm), or Bluetooth audio output. Please check if your TV is compatible before purchasing. 【Usage with smart TV】For smart TVs with built-in Bluetooth (e.g. 2024 Samsung TV), the HT4186 earphones can be paired directly via Bluetooth. In this case, you don't need to use the transmitter, so slide it to "OFF". [No Lip Sync Delay] HT4186 with built-in "FastStream" Bluetooth provides audio latency of less than 40ms. Significantly lower and better than typical Bluetooth solutions on the market that are over 200ms. This feature ensures that audio and visuals are always in perfect sync, no matter what content you're watching. [Use Separately] Do you want to use your 4186 earphones with your mobile phone? No problem! The earphones are highly versatile and work independently without a transmitter. Designed with precision-engineered 40mm stereo drivers, delivering powerful yet stable audio quality for a smooth and dynamic listening experience. 【Add a second headphone】HT4186 supports dual-link audio, allowing you to add a second pair of Bluetooth headphones. We highly recommend using headphones that support FastStream Bluetooth (e.g. Avantree Aria) to provide the best experience without audio lag. (Note: Audio may be off-sync when using non-FastStream devices.)
