The Sennheiser BT T100 is a user-friendly Bluetooth transmitter designed for digital audio transmission. Packed with cutting-edge wireless technology, the Bluetooth 4.2-based BT T100 provides freedom of movement at home while listening to music or watching movies. With support for A2DP profiles and multiple audio codecs, it delivers high-quality audio performance regardless of the situation. The transmitter is equipped with both an analogue input in 3.5mm mini-jack format and a digital input, so it allows the simultaneous transmission of up to 79 channels to two headphones at once. What is more, it will fit easily into any bag thanks to its compact dimensions and low weight of just 85g, offering music lovers a simple and convenient way to enjoy wireless audio streaming.
Pairing Bluetooth-enabled headphones with the BT T100 is simple - all the user has to do is press a button on the front of the device, and the two-colour LED indicator next to it provides connection status updates at a glance. The transmitter can store up to eight Bluetooth headphone profiles internally and connect to two pairs simultaneously for shared listening. The Sennheiser BT T100's frequency response of 20Hz to 20kHz covers the entire spectrum of human hearing to ensure accurate and balanced sound reproduction, and for flawless audio transmission, it supports the Qualcomm aptX Low Latency codec, ensuring perfect synchronisation of sound and image - ideal for TV and home cinema setups when paired with compatible headphones. Additionally, it supports A2DP profiles and the SBC and aptX audio codecs for high-quality wireless sound.
The compact Sennheiser BT T100 enables wireless audio transmission from hi-fi systems, TVs, PCs, and home cinema setups that lack built-in Bluetooth, allowing them to stream sound to Bluetooth headphones. Designed for simplicity, it requires no technical knowledge and offers quick, intuitive setup. Beyond use at home, the BT T100 can also serves as a wireless monitor mix transmitter for live performances by streaming audio to up to two pairs of true wireless in-ear headphones, giving musicians the freedom to move on stage. To achieve this, the monitor mixer output connects to the BT T100's analogue input using a 6.3mm jack adapter (available separately). The included cables ensure flexible integration into any setup, and a 120cm micro USB cable provides the power supply, making the BT T100 ready to use right out of the box.
In June 1945, Prof. Fritz Sennheiser founded the Wennebostel Laboratory, which initially produced measuring equipment. Commissioned by Siemens in 1945, the young company developed the MD-1 microphone, which was launched in 1946. After the development of further microphones, the company was renamed Sennheiser Electronic in 1958. Two years later, Sennheiser introduced the MD 421 dynamic microphone, which is still in production today and still held in high esteem by many sound engineers. Further groundbreaking developments, such as the HD 414 headphones and the classic MD 441 microphone, hugely enhanced the company's international reputation, eventually making Sennheiser one of the leading manufacturers of microphone and headphone systems in the world.
To ensure optimum performance, the BT T100 should be placed as close as possible to the audio source, and users should avoid positioning it near metal furniture or reinforced concrete walls, as these can reduce its wireless range. The transmitter should be connected to an audio source via either the analogue 3.5mm audio input or the digital optical input, using the 1.5m cable included in the package. For older hi-fi systems or record players, an adapter from the relevant connector format to 3.5mm mini-jack (available separately) is required, and users can toggle between analogue and digital formats using a switch located between the two rear-panel connections. The digital connection offers the highest possible audio quality, as it supports PCM streaming for uncompressed sound reproduction.
