Brand: Sony
The Sony TC-177SD is a discontinued cassette audio deck that was produced by Sony Corporation. The model number TC-177SD indicates that it is part of Sony's popular TC (Tape Cassette) line of audio products, and the "SD" at the end signifies that it is a super compact version of the TC-177 model. The super compact design refers to its smaller and more lightweight form factor, making it more portable and easier to carry around. This feature made the Sony TC-177SD popular among users who wanted a high-performing audio deck that they could take with them on the go. However, as technology has advanced and cassette tapes have become less popular, Sony has stopped producing this model.
