The 3.5mm headphone jack was initially introduced in the 19th century, but it's gradually getting phased out since Apple released the iPhone 7 in 2016. Luckily, the iPhone 15 models introduced in 2023 feature a USB-C connector, which offers more options of enjoying lossless music on wired earphones.
The E2023S set provides a pair of Janus3 earbuds and one USB-C terminated decoding cable featuring in-line controls and microphone, which enables you to plug and play.
The front cavity of the Janus3 is sealed and fixed with the driver unit. The driver unit, which sports a dedicated rear cavity, mainly relies on the space and structure of the front cavity for tuning. The CNC aluminum alloy unibody moulding process allows precise machining dimensions down to 0.03mm, ensuring high consistency in the frequency response curve for each pair of Janus 3 earphones. The rear cavity's structural space is used to connect the speaker vent and the earphone socket. The high-strength polycarbonate material is used as the rear cavity, which greatly reduces the weight compared with metal, ensuring that the earphones' centre of gravity is inward facing.
The Janus3 is compact and lightweight, so it fits well even with a small ear canal*
*Small ear canal is a relative term to most people, not big and small. The outer ear canal and auricle size vary from person to person, while the Janus3 is comfortably smaller compared to some of the larger HiFi earphones.
Straight-down wearing is the most common way to use. Select suitable ear tips according to the size of the ear canal, to secure comfortable fit as well as certain sound insulation. The Janus3 is designed with a curved hook angle, when wearing straight-down, the silicone ear tips will have a downward force at the position of the tragus and the external auditory canal, without going too deep into the ear canal, so as to make the wearing more comfortable.

Over-the-ear wearing provides better stability and is generally used during sports activities. The angle of the curved hook will thus probe fully into the external auditory canal, which provides better sound isolation and a more powerful bass experience.

The diaphragm of a driver unit is the key to sound performance, and the dome material is the key core. Both lithium and magnesium have lower density than beryllium's 1.85 g/cm^3, so using lithium magnesium alloy as the diaphragm dome alloy material provides both high rigidity and light weight. Lithium-magnesium alloy also has a very impressive damping coefficient, using it as diaphragm dome can not only dramatically increase the bandwidth and playback more details, but also effectively suppress excess resonance, so that the high frequencies are presented in a more natural way.
For Windows computers without USB-C output, an adapter is required to use the E2023S. For the first time of using the E2023S on your computer, it will be automatically detected as USB and install the driver. The installation completes when it's read as "Realtek USB2.0 Audio".
