Features:

• 2-in-1 Transmitter & Receiver:
  

BTI-077 can be used as either transmitter or receiver. In TX mode, connect the BTI-077 to the audio output device to make the TV/computer/iPad stream audio to Bluetooth speakers or headphones. In RX mode, it can stream music from mobile devices to home stereo or wired speakers. Simply upgrade and modernize old audio equipment.

• Upgraded Bluetooth 5.1 & aptX Low Latency:
  

Enhanced Bluetooth 5.1 technology ensures faster transmission and more stable connections within 33ft working range. aptX low latency achieves end-to-end audio transmission without lip sync delay. Note: aptX-LL requires your receiving headphones/speakers must also support aptX low latency codec.

• Unique OLED Display & 15-Level Volume Control:
  

Unique OLED display abandons the traditional blind pairing so that you can accurately connect to the desired device and get clear info about device status, codec, volume, and battery life at a glance. Easy access volume control makes volume adjustable from level 1 to level 15.

• Convenient Dual Link Support:
  

Supports simultaneous pairing with 2 Bluetooth headsets/speakers in TX mode, or pairing with 2 mobile devices in RX mode to achieve streaming audio. 

• 20+ Hours Long Battery Life:
  

Built-in 600mAh battery provides up to 20+ hours non-stop audio after 3 hours charging. Auto pairing with the last device makes it easy for repeated use.

Important Notes:

• 3.5mm AUX RCA or digital optical? 

In order to stream audio from the TV, it is very important to check the audio OUT ports that your TV can support. ELEGIANT BTI-077 can only be connected to the TV with 3.5mm cable and RCA cable. The audio output method of some LG or Samsung TVs is digital optical OUT instead of a 3.5mm AUX port. In this case, BTI-077 is not the right transmitter for you. You can choose ELEGIANT BTI-066.

• Low Latency Supported? 

Most headphones/speakers are mainly used for music, not for watching TV, and headphones/speakers do not support low latency. In order to avoid lip-sync problems, your headphones/speakers are supposed to support low latency codes. Please contact your device manufacturer to confirm this. Otherwise, the codec will be downgraded to aptX or even SBC, and you may experience significant audio lag. There is no problem with the BTI-077 transmitter.

• Musical Instrument? 

The latency of 40ms is still unacceptable for live sound monitoring. Therefore, those who want to use it with electric piano or guitar, beware! Bluetooth technology, even with Low Latency, may not suit your needs. Not recommended for live music (when playing guitar, keyboard, electronic drums, etc.)

• Hands-Free Call Supported? 

BTI-077 is no built-in microphone. If connected to BTI-077 as a receiver, the microphone of your wired headset will be disabled, so there is no hands-free calling.
