About this item

  • [TV COMPATIBILITY] The HT4186-Q is compatible with TVs with optical (TOSLINK), AUX (3.5mm), or built-in Bluetooth audio outputs. Please confirm your TV is compatible before purchasing.
  • [USING WITH SMART TVS] For Smart TVs with built-in Bluetooth (i.e. 2024 Samsung TV), the HT4186-Q earbuds connect directly to the TV. To simplify setup, we provide an interactive guide that you can access by scanning the QR code on your product when it arrives.
  • [NO LIP-SYNC DELAYS] Enjoy a perfectly synced audio & visual experience at a latency of less than 50ms with aptX Adaptive.
  • [POWERED BY QUALCOMM] With its advanced Qualcomm chipset, the HT4186-Q delivers clearer sound, stable connections, and perfectly synced audio & visual – all backed by Avantree’s 20+ years of Bluetooth expertise.
  • [BOOSTED VOLUMES] Optical connections often suffer from low, unadjustable volumes – the HT4186-Q solves this with a built-in 6dB optical volume boost.
  • [Use them Separately] Want to use the 4186-Q earbuds with your phone? No problem! The earbuds are versatile and can function independently without the transmitter. It is designed with precision-engineered 40mm stereo drivers, delivering powerful yet steady audio quality while ensuring a smooth & dynamic listening experience.

This is a well designed and innovative device that is worth the investment. This essentially proves a set of bluetooth headphones and a transmitter unit. The unit can sit next to your TV or digital box (etc) and it takes an optical or mini jack aux input and is powered by a usb-c cable (adaptor supplied) - the transmitter can also sync with other devices, like bluetooth speakers or third party headphones. This is very well engineered and designed and can be strongly recommended.
