Bluetooth is an easy upgrade. A small adapter can add wireless support to a PC or TV without turning the setup into a hardware project, which is useful because nobody wants to open a desktop case for a feature that fits in a pocket.
For PCs, USB Bluetooth adapters are often simpler to install than PCIe cards and work across more systems. Around $10, the ASUS USB-BT500 and TP-Link Nano 2-in-1 AC600 offer serviceable options for adding Bluetooth to a computer that lacks native support.
USB also avoids one of the basic traps in this category: connector compatibility. Some adapters, such as Noble’s Sceptre, use only USB-C, so check the available port before buying. The smallest adapter is still useless when it cannot physically connect to the machine.
Match the adapter to the wireless job
Not every Bluetooth adapter handles the same type of connection. The Creative BT-W5 is a multi-purpose Bluetooth adapter, while the Avantree DG80 supports AptX Low Latency but is audio-only. That distinction matters if the goal is wireless sound rather than keyboards, controllers, or other components.
Codecs determine how Bluetooth carries audio. SBC is one option, while AptX Low Latency supports a higher bitrate of 352 kbps and can reduce the delay between what appears on screen and what reaches wireless headphones. For watching video, that timing matters more than a feature list packed with irrelevant promises.
For more demanding setups, the Sena UD100-G03 supports up to seven simultaneous connections and reaches 900 feet. Upgrades can extend that range to more than half a mile, which is excessive for a desk but useful when a single adapter needs to cover a much larger space.
The current Bluetooth generation is 6.3, and Bluetooth 5.0 and beyond are backwards-compatible. That makes version support less of a panic button than it sounds, although connection count, range, connector type, and codec support still deserve attention.
Adding Bluetooth to a television
Most televisions made in the past decade likely already support Bluetooth. As Adnan Ahmed put it, “Bluetooth has become mainstream in most televisions now, with many infrared remote controls relying on the technology too.” Before buying an adapter, check whether the TV can connect to the headphones or keyboard directly.
Streaming devices offer another route. Apple TV, Roku, and Fire TV Stick feature Bluetooth as a standard, allowing wireless headphones or keyboards to connect directly. A Roku Streaming Stick HD costs around $30 and can add Bluetooth support to a TV that lacks it.
There is one catch: Bluetooth accessories only work when the TV is set to the input source used by the streaming device. That means a wireless headset paired through Roku will not automatically follow audio from every other TV input. Convenient, yes. Magic, no.
A dedicated Bluetooth transmitter handles a different setup. Plug it into the television’s audio output, using an optical port, 3.5mm headphone jack, or RCA outputs, and it can send sound to Bluetooth headphones or speakers. These transmitters are available at around $25 and need a power source, often through a USB port on the TV.
Choose a transmitter with AptX Low Latency when audio delay is a concern. The codec can reduce the lag that makes dialogue feel detached from the actors, which is a small technical improvement with an obvious payoff.
The sensible choice depends on the equipment already in place. Use a USB adapter for a PC that needs broad, simple Bluetooth support; choose an audio-focused adapter when codec performance matters; and use a streaming device or dedicated transmitter when the television lacks the right connection. Most televisions can last a very long time with the right audio upgrades and a streaming device that unlocks on-demand content.
