Bluetooth transmitter

Which Bluetooth transmitter do I need?

• Audio connection: 3.5 mm, Toslink or coaxial.
• Audio latency: important when watching TV, movies and gaming.
• Number of headphones: some models can connect two pairs of headphones simultaneously.
• Transmitting or receiving functionality: some devices work as both a transmitter and a receiver.

Each model in the Marmitek range is designed for a different application:

• BoomBoom 50: simple wireless TV audio. 3.5 mm connection, SBC codec, one pair of headphones.
• BoomBoom 55 HD: TV, movies and gaming with low latency. 3.5 mm, Toslink and coaxial connections, aptX Low Latency, aptX HD, aptX Adaptive, aptX and SBC, two pairs of headphones simultaneously.
• BoomBoom 100: transmitting and receiving Bluetooth audio. 3.5 mm and Toslink connections, aptX Low Latency, aptX, SBC and AAC (AAC in receiver mode only), two pairs of headphones simultaneously.

BoomBoom 50: a simple Bluetooth transmitter for TV

The BoomBoom 50 is ideal if you want to send TV audio to one pair of Bluetooth headphones. It is extremely compact, making it easy to hide behind your TV. You connect it using a 3.5 mm audio connection and power it via USB. This model uses the SBC codec. Audio latency is approximately 170–270 ms. This is usually not a problem when listening to music. For movies or gaming, a model with aptX Low Latency may be more suitable.

BoomBoom 55 HD: low latency and two pairs of headphones

The BoomBoom 55 HD is suitable for watching TV, movies and gaming. It supports aptX Low Latency, among other codecs, with audio latency of approximately 32–40 ms. You can connect two pairs of Bluetooth headphones simultaneously. This model also features a 3.5 mm audio input, an optical Toslink input and a coaxial digital audio input. To use aptX Low Latency, your Bluetooth headphones must also support this codec.

BoomBoom 100: Bluetooth transmitter and Bluetooth receiver

The BoomBoom 100 works as both a Bluetooth transmitter and a Bluetooth receiver. In TX mode, you can send TV audio to Bluetooth headphones, for example. In RX mode, you can receive music from a smartphone or tablet and play it through an existing sound system. The BoomBoom 100 supports 3.5 mm and Toslink connections, aptX Low Latency and up to two simultaneously connected devices. This model is particularly suitable if you want to both transmit and receive Bluetooth audio.

Which connection do you need?

Before buying, check which audio output your TV, computer or sound system has.

3.5 mm or AUX

Many televisions, computers and other audio devices have an analogue 3.5 mm audio output. Does your device have a headphone output? If so, you can usually use a Bluetooth transmitter with a 3.5 mm input.

Optical or Toslink

Many televisions have a digital optical audio output. This is labelled Optical, Toslink or S/PDIF. The BoomBoom 55 HD and BoomBoom 100 can be connected via Toslink. Not getting any sound after connecting? Check your TV's digital audio settings. With some device combinations, the output must be set to PCM Stereo.

Coaxial digital audio

Does your audio source have a digital coaxial output? The BoomBoom 55 HD also features a coaxial digital input.

When do you need aptX Low Latency?

Every Bluetooth connection causes some audio latency. You usually won't notice this when listening to music. However, when watching TV, movies or gaming, latency can become noticeable if the audio and video are no longer in sync.

aptX Low Latency is therefore particularly useful for:

• watching television;
• movies and series;
• gaming;
• other applications where audio and video need to stay in sync.

The BoomBoom 55 HD and BoomBoom 100 support aptX Low Latency. However, your headphones must also support this codec. Otherwise, the connection will switch to another available codec.

Can you use two pairs of Bluetooth headphones at the same time?

Yes, provided the Bluetooth transmitter supports two simultaneous connections. This is useful if you want to watch TV together while each using your own headphones. Within the Marmitek range, the BoomBoom 55 HD and BoomBoom 100 support up to two simultaneous connections. The BoomBoom 50 does not support this feature.

Bluetooth transmitter or Bluetooth receiver?

• A transmitter and receiver perform opposite functions:
• A Bluetooth transmitter sends audio, for example from your TV to Bluetooth headphones.
• A Bluetooth receiver receives audio, for example from your smartphone and sends it to an amplifier.

Want to stream music from your phone to an existing stereo system? Explore Marmitek's Bluetooth receivers. Want to use both functions? The BoomBoom 100 combines a transmitter and receiver in a single device.

How do you connect a Bluetooth transmitter to your TV?

Connecting a Bluetooth transmitter usually involves four steps:

1. Check which audio output your TV has.
2. Connect the transmitter via 3.5 mm, Toslink or coaxial.
3. Connect the transmitter to a power source.
4. Put the transmitter and Bluetooth headphones into pairing mode.

Once paired, the TV audio is transmitted wirelessly to your headphones. Want to learn more about the connections and settings? Read how to connect the BoomBoom 50.
