The TDK BA100 Noise Isolating In-Ear Headphones were developed and tuned at TDK's Audio Research Lab to provide 26dB of noise isolation. Coupled with its balanced armature micro-drivers, the BA100s are designed to provide clear vocals and full bass. They can be used for the playback of music in a wide variety of applications.
TDK includes a pair of Comply foam ear tips as well as small, medium, and large sized silicone ear tips to provide a choice for comfortable noise isolation. The cable can be worn straight down or over your ear depending on your preference.
The BA100s feature a 20" cable in addition to the included 30" headphone extension cord.
