This document compares the frequency response of Thin Film Technology (TFT) headphones to other high-end headphones from Monster, Sennheiser, Ultimate Ears, Apple, and Audio-Technica. Various TFT models are shown to outperform the competitors in bass response and overall quality, particularly the TFTA-2100 series, while providing similar or better performance at a lower price point. Frequency response charts are presented to analyze the performance of TFT headphones versus these other brands across the audible frequency range.
