Bluetooth Adapters & Audio Modules Specifications
Selecting the correct Bluetooth hardware depends on whether you are transmitting data, streaming audio, or building a custom circuit. Here is a technical breakdown of our core Bluetooth inventory:
| Product Category | Key Technical Features | Best Use Case |
|---|---|---|
| USB Bluetooth Adapters (Dongles) | Bluetooth 5.3 / 5.4, Plug & Play, Backwards compatible | Upgrading desktop PCs to connect wireless mice, keyboards, and headsets. |
| Audio Transmitters & Receivers | 2-in-1 TX/RX modes, DAC, NFC, aptX Low Latency support | Bridging non-Bluetooth TVs or vintage Hi-Fi amplifiers to modern wireless headphones. |
| DIY Audio Decoder Boards | Bluetooth 5.0+, Lossless Audio decoding, 5V-12V input | Custom speaker builds and engineering projects requiring embedded wireless audio. |
Important Note (Hardware Limitations & Latency): A very common mistake is attempting to plug a USB Bluetooth Dongle into a TV or car stereo's USB port to transmit audio. This will not work. USB dongles require a Windows or Linux operating system to install drivers. To transmit audio from a TV, you must use a dedicated Bluetooth Audio Transmitter connected via a 3.5mm AUX or Optical cable. Furthermore, while Bluetooth 5.4 offers excellent range, it inherently has latency. For competitive FPS gaming, we strongly recommend dedicated 2.4GHz wireless headsets over standard Bluetooth.
Frequently Asked Questions (FAQ)
Q: Can I connect two pairs of Bluetooth headphones to one USB adapter on my PC?
A: No. While a standard USB Bluetooth adapter can connect multiple different types of devices simultaneously (e.g., one mouse, one keyboard, and one headset), Windows OS restricts audio output to only one Bluetooth audio device at a time. If two people want to watch a movie using wireless headphones, you need a dedicated Bluetooth Audio Transmitter with a "Dual Link" feature.
Q: Why is there a lip-sync delay when watching movies using my Bluetooth receiver?
A: Audio delay occurs when the transmitter and receiver use the basic SBC codec, which typically has a latency of 150-250 milliseconds. While fine for music, this causes noticeable audio-visual desync in movies. To eliminate this, both your transmitter and headphones must support low-latency codecs like aptX Low Latency (aptX-LL). We stock low-latency transmitters in-store for you to test.
