Higher than the Stars - Hidizs MS1 Review

Project A³  |  March 13, 2020

Introduction:

Hidizs is no stranger to the portable-audio scene, having manufactured and sold a wide consortium of audio-related products. Having launched several projects on the Kickstarter platform, from the widely celebrated AP80 Digital Audio Player (DAP) to the Mermaid MS1 and MS4 earphones, Hidizs is more than just a proof of concept, with the AP80 collectively earning 20 times their goal, with the MS4 receiving 10 times the targeted amount.

In the spirit of prior successes, The MS1 Rainbow is looking to capitalize on that success. Priced at $65.00 USD, the MS1 Rainbow touts a 10.2mm bio-cellulose driver. Given the reasonable price-tag, will the Hidizs MS1 Rainbow carry on Hidizs' winning streak? Available at Hidizs and Aliexpress.

Specification:
· Hidizs 10.22mm dynamic driver with macromolecule bio-diaphragm
· Frequency Respnse: 20-40kHz
· Support call and wire control functon
· German high-ensity and skin-friendly resin housing (colorful and fashionable)
· 4 core silver-coated OFC cables
· Two pins 0.78mm plugs and support cable replacement
· 3.5mm gold plated plug
· SPL: 112dB
· Impedance: 20 ohms
· Weight: About 6g

Unboxing:

The Hidizs MS1 Rainbow comes stashed in an attractive, rectangular box. Inside the box, you'll find a leatherette pouch, the MS1's themselves without the the cable attached to them, several silicon eartips and a few instruction manuals.

The MS1 Rainbow satisfies most of the pre-requisites I would expect from an earphone out of the box, but a hard-zippered case would have been a nice touch. However, I am thoroughly satisfied with what I have received.


Scalability:

All the sources that I own have high output power, and the Hidizs MS1 is an earphone that isn't power or current hungry. With a given impedance rating of 20 ohms, the MS1 is easily driven by both my Super X-Fi DAC, at 12 steps out of 100. Furthermore, the Dethonray DTR 1 (on low gain), reaches adequate listening levels at approximately 30 steps out of a 100.

The Hidizs MS1 is an IEM that doesn't require a high-powered source for it to sound great. The in-line microphone is a clear signal that the MS1 Rainbow was targeted at an "on-the-go audience".

However, because of this, the MS1 doesn't scale exponentially with higher-end gear. Audible improvements made by changing the source gear doesn't result in large changes. Your mileage may vary. 

Fit:

The shells are feather-light, coming in at a minuscule 6 grams. It sits flush in my medium-sized ear canals, and I don't see or feel any unfinished surfaces. However, the seam that separates the shell from the face-plate isn't finished or sealed with lacquer.

Using the MS1 Rainbow was a comfortable experience. I never felt any discomfort, and I barely noticed its presence in my ears on the bus-ride to school.

Isolation is above-average, but like all dynamic-driver based earphones, small vents are a necessary evil to release air-pressure generated dynamic driver's back-waves. Because of that fundamental feature, wind has a tendency to generate unwanted noise, significantly affecting its ability to isolate well.

Lastly the cables are well-braided, with a smooth cable sleeve. The hardware utilized for the Y-split, the in-line microphone and the 3.5mm jack are well-finished and feature custom tooling, with their brand name printed onto the 3.5mm jack. It rolls-up nicely, without forming a tangled mess.
