The primary difference between the DB1 and the DB1E model is the driver sensitivity and impedance. The DB1E uses a high-sensitivity and medium-impedance driver with 80Ω impedance and 107dB sensitivity. It uses imported black copper-clad aluminum coil. Temperament DB1 adopts a high-sensitivity and low-impedance driver with 30Ω impedance and 110dB sensitivity. DB1 uses an in-house developed pure copper coil for improved sound performance. Professionally Designed Titanium Alloy Acoustic Cavity Structure:- DB1 series of earbuds adopts a professionally designed Titanium Alloy Acoustic Cavity Structure. Temperament(K’s Earphones) have got more than 10 years of experience in designing premium flat-head earbuds. With that expertise, they have designed the DB1 Series’s cavity structure delivering a super strong lower-end response!!! Powerful Performance With A Large Dynamic Driver Unit:- Temperament DB1 series of flat-head earbuds promises a powerful sound performance with a deep-hitting lower-end, transparent midrange, and a smooth treble region, all thanks to their 15.4mm large dynamic driver that uses Diamond cut suspended diaphragm coil and a powerful Tesla-level magnetic circuit. Finely-Crafted Ear Shells Using Five-Axis CNC Machining Process:- Temperament DB1 series of flat-head earbuds features high-quality 316L Stainless Steel ear shells. The shells are crafted using a high-precision 5-axis CNC machining process. The DB1 series boasts the same ergonomic shape and design as the Bell Series by K’s Earphones. The pairs are super comfortable and ensure an easy listening experience. High-Quality Modular Stock Cable With Swappable Terminations:- DB1 series of earbuds have a modular cable design. The cable is in two parts, the main part consisting of a two-pin connector cable and the sub-cable part with termination plugs. The package for both DB1 and DB1E includes 2.5mm, 3.5mm, and 4.4mm plugs in the package.
