NF ACOUS RA05 USB-C IEM Earphones With MEMS Microphone

Why A USB-C Wired Earphone Makes Sense For Phones And Laptops

Many phones, tablets and laptops no longer have a 3.5mm headphone socket, which leaves a wired earphone with a USB-C plug as the simplest way to get good sound without a Bluetooth connection. There is nothing to pair, no battery to charge and no lag, and the earphone works as soon as it is plugged in.

The RA05 is built for that kind of everyday use. It has a dynamic driver tuned for clear, balanced sound, a built-in microphone for calls and online meetings, and a lightweight housing that stays comfortable over long sessions.

NF ACOUS is rapidly building a reputation among musicians and audio professionals by engineering in-ear monitors and studio headphones that prioritise clinical precision.

Available now at Audio Direct, these monitors consistently earn high praise in customer reviews for their outstanding detail retrieval, lightning-fast transient response, and exceptional vocal clarity.

Models like the NM25 and NA20 feature lightweight, ergonomic resin shells that guarantee fatigue-free comfort during marathon mixing sessions or live performances.

Description

Reference-Level Accuracy In A Machined Aluminium Shell - NF ACOUS NM25 In-Ear Monitors

The NF ACOUS RA05 is a USB-C wired in-ear earphone with an MCL-6C dynamic driver and a high-performance MEMS microphone. It delivers balanced, engaging sound with clarity, natural tonality and detail, and suits music, calls, online meetings, video and mobile gaming on any device with a USB-C port.

Sound And Acoustic Design

The 6mm MCL-6C dynamic driver is paired with breathable acoustic damping for a smooth, refined sound. NF Acoustics also lists DSP customisation as a feature. Sensitivity is 102 dB/mW with a 16 ohm impedance, and the frequency response runs from 15 Hz to 30 kHz with distortion below 1%.

Calls And Connectivity

A MEMS microphone gives clear voice communication for calls and meetings. The USB-C connection is plug and play, with no batteries or charging, and it uses a 5N oxygen-free copper cable.

Really happy with the PC and the service received. Communication was excellent throughout the build process. All delivered in good time and received with plenty of helpful advice, especially from Kieran after delivery to help me set it up.

Will definitely recommend. Many thanks

Michael Cole

Very bright and easy to see

M butcher

Ordered guitar strings which arrived in two days, inside package was an offer for a guitar tuner which also arrived in two days. Excellent customer service.

Terence Hamilton

At the offer price this was very good value for money. I have generally found Snark tuners to be very good although with the low tunings I use I often find they can take a little time to give an accurate reading moving from string to string. Otherwise, Great!

Jake Glanville

The Snark SN1X clip on guitar tuner is a very handy and accurate tuner, very easy to use and at a great prices too! 👍🌟🍺😸

Jason Davey

This is my second Snark Tuner, there are various versions, this one is for use at home the other is RF shielded and has rubber protection incase dropped. Both work excellent and are the best clip-on tuners I have used. The service given by Audio Direct was first class, Dave even telephoned me to discuss a query I had not something many online traders would do so overall 10/10

Elfed Weaver

Brilliant company and good prices, many thanks 🙏

Powerful, purpose‑built music production PC that fits extremely well with the demands of Asian music

If you’re into producing Asian music — Bollywood & Bhangra this system is exactly what you need

i have huge sample libraries — sitar, tabla, erhu, taiko drums — plus modern synth layers and this PC handles all of it without breaking a sweat.

Musical, dependable looper offering rich stereo sound, generous memory, and helpful rhythm options. Ideal for practice, songwriting, and live performance

It sounds like it's supposed to sound, easy to shape the tone on each of my electric guitars. Yes, each of the amplugs is a one (or two) trick pony, but they do what they're supposed to well, and they each sound like the amp they emulate.

Daniel

Really good clear display, large screen for easy use. Light touch activation button, accurate tuning. Sturdy strong feel but light, Nice shade of blue shell. fits securely to headstock, easy to detach. Pleased with my purchase.
