With the continuous advancement of transmission technology, Bluetooth music playback has gradually moved from a supporting role to the forefront, with its sound quality slowly being accepted by discerning audiophiles, becoming an option among audio system sources. Many audio products priced in the tens of thousands have also integrated Bluetooth music playback functionality. In this issue, we have selected 10 products equipped with Bluetooth music reception capabilities to share with you. These 10 products all utilize the most advanced Bluetooth receiver modules currently available, supporting industry-trusted transmission protocols such as AptX-HD or LDAC, and with careful tuning by the manufacturers, they are capable of making Bluetooth music Hi-Fi.Brief Reviews of 10 Audio Products with Bluetooth Reception Functionality
TECSUN (德生) BT-80 Bluetooth Hi-Fi Transceiver Reference Price: ¥2,000 per unit>Receives and transmits>Supports aptX HD and LDAC encoding technologies>Coaxial digital output>Built-in battery Previously, TECSUN launched portable Bluetooth headphone amplifiers, namely the BT-50 and BT-90. The newly launched BT-80 is also part of this series, but the BT-80 is designed for Hi-Fi systems, with specifications that are not comparable. The appearance style of the BT-80 is consistent with the PM-80, CD-80, and TU-80, all adopting a compact body with a low-key black color, and the panel features milky white square buttons and indicator lights, giving it a professional equipment vibe. TECSUN’s BT-80 uses the Qualcomm CSR8675 flagship Bluetooth chip, which supports aptX HD and LDAC encoding technologies. Although the Qualcomm CSR8675 flagship Bluetooth chip comes with its own decoding, smart manufacturers bypass it and design independent decoding circuits, which can enhance sound performance. TECSUN’s BT-80 does exactly this, pairing the CSR8675 with the high-performance ESS9018Q2C decoding chip, with the purpose being self-evident. In addition, the BT-80 uses a rechargeable lithium battery for power, consisting of two 18650 batteries in parallel, providing a capacity of 5200mAh. Compared to AC power, batteries are a clean power source that does not introduce noise and interference from the AC grid. When used as a receiver, the BT-80 can connect to two devices simultaneously, although it cannot play music from both at the same time. Besides having an analog output, it also features a coaxial digital output interface for easy connection to external decoders. Unlike most Bluetooth Hi-Fi receivers on the market, the BT-80 is not just a simple receiver; it is a transceiver that can receive Bluetooth signals and also transmit Bluetooth signals. This transmission function supports both analog input and digital coaxial input.
Review: The BT-80 is TECSUN’s first desktop Bluetooth Hi-Fi transceiver, combining Bluetooth receiving and transmitting functions, while also featuring decoding input and headphone output. For those who have not experienced Bluetooth 5.0 and aptX-HD encoding, the sound performance of the BT-80 will surely change your previous impressions of Bluetooth audio, allowing you to experience a significant improvement in sound quality. Considering the functionality and sound performance of the BT-80, it has the potential to become a new member of Hi-Fi systems and a new toy for audiophiles.■ Type: Bluetooth transceiver, supports aptX-HD ■ Input: Bluetooth 5.0, digital coaxial, RCA ■ Output: Bluetooth 5.0, digital coaxial, RCA, 3.5mm headphone jack ■ Built-in battery: 3.7V (2 x 18650 lithium batteries) ■ Frequency response: 25Hz-20kHz ■ Dimensions: 212×43×282mm ■ Weight: 1.608kg
