Most people tend to immediately associate headphones with listening to music. Given the habits, habits of society and the history of typical marketing, it makes sense. However, due to the popularity of modern high-definition TV, cheaper prices, cheaper prices, the use of wireless Bluetooth technology, headphones can also make video consumption has become a fantastic trend. So why not? There are more headphones to choose from, many of which offer a lot of features and solid audio performances.
If you want some privacy, want to consider the people around, if you like to wear a comfortable headset fluff, do not limit your experience just to music. Watch your TV with headphones!
Some may ridicule this idea, but there is reason to want to connect the headset to the TV. You may like to enjoy your own entertainment bubble, which is not affected by the surrounding environment, such as street traffic, neighbors, running appliances (such as washing machines, dryers, HVAC), roommates, pets, tourists or children. If you want a better bubble, the Bluetooth headset uses active noise cancellation (ANC) technology to find popular choices from companies like Bose, Sony, Sennheiser, Phiaton, etc., which can effectively eliminate most of the environment / ambient sound .Or maybe someone else, you do not want to bother watching TV, for example, people who may be sleeping or quietly reading in the neighborhood.
Because they are headphones, can only hear the audio. If the headset is also Bluetooth wireless, you can freely roam the room to the room without causing the inconvenience of the cable. Of course, in another room, watching movies seem silly, but some of us may like to listen to the morning news on TV.
In addition, when two or more (yes, multiple is possible!) People use the Bluetooth headset to watch the video, each can set their own ideal volume level. No more combat remote control!
Unlike a simple pairing of mobile devices, there is a little more idea when connecting a Bluetooth wireless headset to a TV. This is what you need to do:
Check if your TV has Bluetooth
Connecting a laptop to a Bluetooth mobile device is very simple, and there is not much difference in headphones. However, although Bluetooth seems to be in a variety of electronic products, but most of the TV are not worthy of Bluetooth. And those (usually smart TV) content does not always publish a Bluetooth connection on an external package. If you have a regular / standard TV (either LED, LCD, plasma, CRT, etc.) and know it, then you only need a Bluetooth transceiver / transmitter or two can be set with your headset.
Otherwise, if you have a new HDTV or smart TV, and you are not sure whether you have Bluetooth, please read the product manual and give it to reading (sometimes available online). You can also practice by investigating the TV’s menu settings. Turn on the TV, enter the system menu, and then scroll / navigate to the location where the sound option is located.
You can also check under the “Accessories” menu option, because some televisions use this part to connect the Bluetooth headset (except for input devices such as the mouse and keyboard). You may have to poke a bit, because there are usually a variety of features to view. When you see the option to add a Bluetooth device, follow the on-screen instructions to pair your headset.
If your TV does not have Bluetooth, or if it is, but can only pair with the input device – do not despair! All you need is a wireless transceiver / transmitter. But before you start searching for one of them, you first need to know the output port you are using.
Identify Available Audio Output
The type and number of audio output connections depends on whether you are using a TV or a stereo receiver / amplifier as the central part of the entertainment system. For example, if you watch a local / cable channel and / or a DVD player that is directly connected to a TV, you will know that the audio is passing through the TV. Therefore, you can connect the Bluetooth transceiver / transmitter to the TV so that you can send wireless audio to the headset.
However, if you connect a cable box or a DVD / media player to a stereo receiver, the audio will pass through the receiver (and may also be sent to the connected speakers). So, in this case, you connect the Bluetooth transceiver / transmitter to the receiver instead of the TV because the receiver is processing the audio output. Remember that the headset will need to click on the audio source, otherwise you will not hear peep.
Once you have determined which device should have a Bluetooth connection for audio output, you need to view the available physical output connections. Common types are HDMI, Optical / TOSLINK, RCA and 3.5 mm audio jacks. Your typical TV is only RCA connected, and the rest can be found on many stereo receivers (and updated HD televisions). See which audio output connections are available for free, as this will help determine which Bluetooth transceiver / transmitter you need to get.
Be careful when using any 3.5 mm jack labeled “headset” because inserting anything can sometimes cut off the sound being played through the speaker. It is important that you want to use the Bluetooth headset to enjoy the TV at the level you need at the level without interrupting the speaker audio of other people.
Select and Connect Bluetooth Transceiver/Transmitter
There are many Bluetooth transceivers (a combination of transmitter and receiver) and the transmitter is there, but only those with the right hardware can work properly. The key is to select the audio with a low latency Bluetooth adapter (not just the Bluetooth adapter) to keep the audio synchronized with the video (continued in the next section). Otherwise you will see and hear there will be a delay.
If you plan to use an RCA or 3.5 mm connection to output audio to a Bluetooth headset, we recommend using the TROND 2-in-1 Bluetooth v4.1 transmitter / receiver. It is compact, affordable, rechargeable, with its own cable, and supports low latency two transmitter and receiver modes. Why is this important? To check your headphones. If your Bluetooth headset does not support low latency – or if you want to use Bluetooth to upgrade your wired headset, you need to select a pair of Bluetooth transceivers. Set a send mode and connect it to the TV / receiver audio output. Connect another receive mode and insert it into the 3.5 mm jack on the headset.
If you plan to use the Optical / TOSLINK connection to connect the audio output to the Bluetooth headset, we recommend using the Indigo BTRT1 Advanced Bluetooth aptX Low Delay Transmitter / Receiver. It is similar to the above products, in addition to 3.5 mm port, but also has the optical input / output additional advantages. Batteries like this are missing internal batteries and need to continue working from nearby sockets to make them more suitable for use with televisions or receivers.
If you plan (or must) use an HDMI connection for audio output, we recommend using an HDMI converter. Although you can find options for wireless HDMI audio / video transmission hardware, they typically cost hundreds of dollars. The HDMI converter converts the HDMI signal to Optical / TOSLINK and / or RCA. Therefore, in this case, you will still use one of the aforementioned transceiver / transmitter in conjunction with the HDMI converter.
Once you need to use the Bluetooth adapter, follow the instructions. When you test together, make sure to select the correct audio output on the TV / receiver.
Note: Some emitters can send audio to 2 pairs of bluetooth headsets at the same time. Although it sounds great, but this does not lead to low latency. Keep in mind that low latency is critical to audio / video synchronization. So what if you want to connect multiple Bluetooth headsets? The best way to do this is to use a simple audio / headphone splitter – you need to select the RCA / 3.5 mm output option to make it work. Use the audio cable to connect the TV / receiver to the headphone splitter. Now you can insert multiple transceivers / emitters into the headset splitter; one for each pair of headphones you want to use. Ensure that each wireless pairing is performed separately to avoid potential device confusion.
Resolve Bluetooth Audio/Video Sync
A reasonable problem with using a Bluetooth wireless headset with video content is the potential to delay audio. When you find a minute on the screen, you will recognize it. If you have a more modern TV (smart TV and / or HDTV), you can check the built-in solution. Find the “audio delay / sync” setting (or something named) under the sound options in the TV system menu. If present, the adjustment should appear as a slider / bar or box, and its value is usually in milliseconds. Sometimes you may see a list of all the individual inputs / outputs that can be adjusted. Moving the slider / number down should help minimize the delay and synchronize the audio with the video.
In rare cases, you may encounter video instead of audio delay. This happens when streaming content is streamed because the video (sometimes buffered) takes extra time on the screen, which causes it to lag behind the sound. In this case, you can adjust the sound settings to increase the audio delay, slow down the volume, and synchronize it with the video. Make small adjustments and tests until you find the perfect match.
For best results, make sure your smart TV is using the latest firmware update, as this may affect options and / or performance. If you are still experiencing audio / video sync issues, check if any of your TV’s sound settings are not currently set to “Standard”. Enabling various sound modes (such as virtual, 3D audio, surround, PCM, etc.) may inadvertently inject delay. If you stream video through an application or a separate device (such as YouTube, Netflix, Amazon FireTV, AppleTV, Microsoft Xbox, Sony PS4, Blu-ray player, Stereo Receiver / Amplifier), double-check the physical connection and audio Each setting.
Older electronic devices may lack these audio adjustment settings. Therefore, the best way to keep audio and video synchronized when using a Bluetooth headset is to select hardware that supports low latency Bluetooth.
Low Latency is Critical
If you are using a regular TV and / or receiver, Bluetooth wireless audio / video synchronization issues may not exist with the correct product. Looking for Bluetooth APTX low latency – it needs to work on both headphones and / or transceiver / emitter. Low latency Bluetooth has a delay of no more than 40ms, which creates the appropriate synchronization between what is seen and what is heard. As a reference, a typical Bluetooth wireless headset exhibits an audio delay from 80 milliseconds to 250 milliseconds. Even at 80 milliseconds, our human brain can feel the video delay of audio, so with a low latency Bluetooth aptX is vital.
If you want to browse many known Bluetooth aptX compatible products, you can visit the aptX website. Although the list is updated frequently, they do not necessarily show all the content. So do not be afraid to do some Google search for more information.
