Hidizs has prepared two new models of in-ear monitors under a common name and some features shared between the two. Main code name is «Mermaid» with the additional labels «MS4» and «MS1». Mermaid MS4 is more advanced hybrid model based on three BA drivers by Knowles and one dynamic driver while MS1 features the same single dynamic driver unit.
Hidizs Mermaid MS4 specifications:
The most exiting is the choice of optional accessories Hidizs would provide the both models with:
- Type: Hybrid, 3BA + 1DD
- BA units: Knowles 33518 (high frequency) + 30017 dual
- Dynamic driver: 10.2mm, Hidizs design, high-sensitivity polymer diaphragm (dual magnetic circuits|dual cavity)
- Shell materials: high density military grade CNC aluminum-alloy, aluminum-alloy gold-plated output nozzle, hand-made resin top panel
- Frequency response: 15Hz - 40kHz
- Sensitivity: 112dB/mW
- Impedance: 12Ω (at 1kHz)
- Rate power: 10hW
- Headphone connectors: 2pin, 0.78mm
- Cables: OFC, 4 strands
- Weight: 16g
- audio cable with the regular 3.5mm jack (included, stock)
- audio cable with 2.5mm balanced jack
- audio cable with 4.4mm balanced jack
- following the recent trend: several modern DAPs were released with Pentaconn 4.4mm (JEITA standard) balanced outputs and general tendency of DAP manufacturers to incorporate this standard instead of 2.5mm balanced output
- audio cable with USB DAC ((type-C) + type-C->USB A coneverter))
- possibility to get better driving ability and more balanced sound instead of using low quality audio outputs from smartphones, PCs or tablets.
- CS42L42 chip
- Up to 24bit/192kHz
- 75mW + 75mW @ 32ohms output power
- SNR: 117dB
- Dynamic range: 115dB
- Distortion: <0.0006%
- Built-in microphone for voice calls
- Bluetooth 5.0 audio cable
- gives a wireless freedom with a support all of common bluetooth transfer protocols (getting the data which ones exactly)
