Tin HiFi T1S is a successor to the famous T1 Plus which brings several improvements in sound with its re-developed acoustic silicone sleeve. T1S adopts a redesigned acoustic cavity structure that improves the mid-range response and better vocals, and at the same time produces a powerful bass response. Redesigned Dynamic Driver With Beryllium-plated Diaphragm:- Tin HiFi T1S features a 10mm dynamic driver unit. This driver adopts a beryllium-plated diaphragm. Beryllium is an extremely lightweight and robust material that provides a faster response with lower distortion compared to other diaphragm materials. Tin HiFi has provided 98% beryllium plating on the diaphragm. With this, the pair benefits the user by producing a rich midrange, deep-hitting impactful lower-end, and smooth yet detailed treble response. Professionally Adjusted Tuning:- Tin HiFi has got years of expertise in designing single and multi-driver IEMs. Improving the tuning profile of the famous T1 Plus, the T1S brings a re-developed acoustic silicon sleeve and a new brass cavity for its dynamic driver. They help in improving the sound tuning with a clean midrange and smooth vocals. Ergonomic Design For A Comfortable Wearing Experience:- Designed after a study on multiple ear samples, the T1S has got an ergonomic shape with solid resin shells. Each earphone weighs just only 3.2grams. It’s so lightweight that you won’t even feel it inside your ears. An extremely comfortable wearing experience is guaranteed. High-Quality 2-pin Connector Cable:- Tin HiFi has included a high-quality silver-plated wire with standard 0.78mm 2-pin connectors. It allows the pair to perform true to its potential with no low signal loss during transmission. The cable has a 3.5mm gold-plated plug.
