  • HASSLE-FREE SET UP - No need to go through the complex Bluetooth pairing process; simply plug the HT4186’s transmitter into a power source and your TV’s audio output port, power everything on, they’ll quickly connect with each other, and you should be good to go. Works brilliantly with older Non-Smart TVs as well.
  • UNIVERSALLY COMPATIBLE - Thanks to Avantree HT4186’s Optical, AUX, and RCA input cables, it is universally compatible and works with all TVs on the market, smart or non-smart. With it, you’ll be able to listen to your favorite movies at your own volume; you’ll no longer have to turn the speaker volume way up and disturb your family or neighbors.
  • NO LIP-SYNC DELAY - With "FastStream" Bluetooth built-in, the HT4186 provides <40 ms audio latency – significantly lower and better than the 200+ ms of typical Bluetooth solutions on the market. With this feature, no matter what content you're watching, the audio and visual will always be perfectly synchronized.
  • USE THEM SEPARATELY - Want to use the 4186 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.
  • ADD A 2ND HEADPHONE - The HT4186 supports dual-link audio and allows you to add a 2nd pair of Bluetooth headphones to it. We highly recommend using a headphone that supports FastStream Bluetooth (e.g. Avantree Aria) for the best no-audio-lag experience. (Note: Audio may become off sync if you use a non-FastStream device).

Top Questions

  • How to get My Avantree TV Headphones / Transmitters work well with my Samsung Smart TV?

    If you're using one of the latest Samsung Smart TVs, you could encounter an issue when using Bluetooth Transmitters or Headphones. The issue is due to the fact that Samsung Smart TVs tend to pair with any Bluetooth devices it can find unless you manually deny the connection. 

    This could lead to odd behaviors on your Samsung TV such as no picture, Blue / Black Screen with an error message, TV headphones and base not reconnecting, no sound on TV headphones, transmitter cannot pair to headphones, etc. 

    Bear in mind when using Samsung Smart TVs: 

    1. If your headphones / transmitters suddenly stopped working with your TV, it may be because your Smart TV performed an automatic update and reset all of its settings to its original form. Smart TVs also do automatic updates because they are connected to your Wi-Fi, just like a computer. Even though you didn't do anything, the TV changed itself. In these cases, follow the steps from the beginning to troubleshoot the issue.
    2. The TV remote control does NOT turn TV off. It only puts the TV into standby mode. The TV will still perform its "Smart" functions in standby mode. For example, the Samsung TV will still aggresively connect to all devices it finds. The best way to turn the TV OFF is to physically switch it OFF or to pull the plug.

    Here is the FIX for the above issue with Avantree TV headphones and transmitters.

    1. REMOVE / DENY the Avantree Device from Samsung TV's "External Device List."
    2. Keep the TV OFF (Not in Standby) if you have any issues reconnecting the headphones and the base. 

    DENY the Device:

    When the Samsung Smart TV detects your Avantree Device, a popup will appear on the screen, asking you to Allow or Deny the device to connect to the TV. You MUST DENY the device from connecting, otherwise it will not be able to connect with the other device in its set.

    REMOVE the Device:

    If you did allow the device to connect to your TV, or if your device connected to your TV automatically, you will need to remove the device from within your TV's settings.

    Settings >> General >> External Device Manager >> Device Connection Manager >> Device list - >> Edit >> Select all Avantree Device >> Delete

    After removing / denying the Avantree device from the Samsung TV's external device list, your Avantree devices should work properly now. If not, you might need to re-pair & lock the headphones with the base again. Here is how to do it:

    1. Turn OFF your Samsung Smart TV. Either flip the physical switch on the TV, or pull the plug from power. If you cannot physically turn OFF your TV, an alternate method to try is to press and hold the power button on your TV remote for 6 seconds until the TV turns off.

    2. Turn on your Headphones and Transmitter. It is recommended to have your transmitter plugged into a wall outlet, not your TV, as the TV should be off at this point.

    3. Get the Headphones and Transmitter into pairing mode (rapidly flashing RED & BLUE). For more information, please refer to your devices' user manual or support site. 

    4. If your Headphones and Transmitter have a LOCK function, please LOCK the headphones and the transmitter together. For more information, please refer to your devices' user manual or support site.

    Now, the headphones and transmitter will be locked together, so that the next time you use them they should automatically re-connect with each other and show solid BLUE on the headphone. NO need to re-pair them each time.

    If this does not fix it, pls contact support@avantree.com.

  • How to PAIR, CONNECT and LOCK headphones to transmitter again in HT4186?

    All of the Avantree TV headphones sets are "FACTORY LOCKED" before shipping. This means that as soon as they're turned on, they should automatically connect with each other and show Solid Blue on the headphones. There's NO need to pair them each time you want to use them.

    If they still fail to connect, please follow the steps below to RECONNECT and LOCK them together again.

    Note: During this procedure, please use another power source to power up the transmitter instead of using the TV's USB port. After that, temporarily keep your TV turned off. This is because Smart TVs often interfere with the paring process.

     

    1.     Get the Avantree Audikast Plus transmitter into Pairing Mode

    ·       Connect the Audikast Plus to a power source and turn it on.

    ·       Press & Hold the “A”/”1” button until you see the Bluetooth indicator flashing RED & BLUE.

    2.     Get the Headphones into Pairing Mode.

    ·       Make sure the headphones turned OFF.

    ·       Make sure that the earbuds are off. From there, hold the power button for about 5 seconds until the LED indicator alternates between flashing RED & BLUE.

    3.     Wait for them to Connect. Once connected, you will see "FS" and "A"/"1" turn solid on the transmitter. The headphone will turn solid BLUE.

    4.     Lock them up again - Press & hold the "A"/"1" button on the transmitter for about 10 seconds until the "A"/"1" indicator turns PINK for a couple seconds. Now, the transmitter and the headphones are LOCKED and will always link to each other once turned on.

    If you're still having issues, please email support@avantree.com for further assistance.

  • Can I have audio through my TV's Speakers AND Wireless Headphones at the Same Time?

    Hearing audio through the TV speaker AND the headphones at the same time

    If you'd like to get sound on both your TV speakers AND headphones at the same time, it DEPENDS on whether the TV is able to support getting sound out to two sources simultaneously. It is NOT related to the transmitter. The transmitter receieves the sound from your TV's output and streams it over to your Bluetooth headphones or speakers.

    However, if you connect the transmitter to your TV via OPTICAL port and you can see the following options under the SOUND OUTPUT settings on your TV...

    You can actually get sound simultaneously! Follow these steps:

    1. Go to SOUND OUTPUT and change this to OPTICAL / EXTERNAL SPEAKER
    2. Once there's sound going out into the headphones, go back to SOUND OUTPUT and change this back to TV SPEAKER

    If your TV doesn't support simultaneous output to both the TV speakers and headphones, here are some alternative methods you can consider:

    For Audio Transmitter Users:

    Solution 1: Connect the Transmitter to a TV box / AV Receiver instead

    If you have a TV box (DirecTV, Xfinity, Bluray Player, etc.), you should be able to find audio output ports on the back of them. Try to connect the Avantree transmitter directly here instead of the TV. This method essentially allows you to "go around" the TV's built-in speakers.

    Con: will not work on streaming apps if you have a Smart TV or streaming device

    For all users:

    Solution 2: For users with TV Sondbar / AV Receiver

    2.1 Use Transmitters with Passthrough Function

    If you have a Soundbar or Stereo Receiver, check your transmitter to see if it supports passthrough. If not, you can return your current product and consider purchasing one of these: Orbit, Oasis Plus, Opera, Medley 6018, HT5009, HT5006, Duet, or Quartet.

    Our industry leading "Passthrough" function allows you to put the transmitter/base between a TV and an external speaker and have audio come out from both devices AT THE SAME TIME.

    2.2 Use Audio splitter/extractor

    • For AUX Output - Use an audio splitter (e.g. Avantree TR302) to share the TV's audio between an EXTERNAL SPEAKER and the Transmitter. The splitter in this example is a 3.5mm audio splitter

    • For Optical AUDIO OUT - Use an optical splitter (e.g. J-Tech splitter) to share the TV's audio between an EXTERNAL SPEAKER and the Transmitter. The splitter in this example is an optical audio splitter.

    • For HDMI ARC OUT - Use an HDMI Audio Extractor (e.g. HAX05) to share the TV's audio between an EXTERNAL SPEAKER and the Transmitter. The splitter in this example is an ARC supported HDMI audio extractor.
