7Hz G1 IEM | 10mm DLC Dynamic Driver

Q: Is the 7Hz G1 a planar or a dynamic driver?

It is a single 10mm dual-cavity dynamic driver with a Diamond-Like Carbon (DLC) diaphragm - not a planar. The stiff DLC diaphragm gives fast, clean, detailed sound.

Q: Does the 7Hz G1 need an amplifier?

No. At 18 ohm and 107 dB/V it plays loud and clean from any phone, laptop or USB-C dongle. No amplifier is required.

Q: What does it sound like?

Balanced and natural. It is tuned to the Harman target, so vocals are clear and the overall tonality is even and easy to enjoy across genres.

Q: Does it have a microphone?

Yes, if you choose the mic-cable version - it adds an HD inline microphone for calls and gaming. The plain version is audio-only, and you can add a mic later with any 0.78mm 2-pin mic cable.

Q: Is it good for gaming?

Yes - the clean, balanced tuning keeps footsteps and cues clear, and it is comfortable for long sessions. Use your PC or console mic, or add a mic cable.

Q: Can I upgrade or replace the cable?

Yes. The 0.78mm 2-pin connector is a universal enthusiast standard, so you can fit upgrade cables, balanced cables or a Bluetooth adapter.

Q: Which ear tips should I use?

Size for a firm seal first. Wider-bore tips open the treble; foam tips add isolation and warmth. Four pairs are included to experiment.

Q: How is it different from the 7Hz Zero series?

The Zero models use a twin-dynamic-driver design, while the G1 is a single DLC dynamic driver tuned to Harman - a clean, coherent, single-driver sound.

Q: Do I need to burn it in?

No. Any change from burn-in is subtle, so you can use it straight out of the box.

Q: What is included and what is the warranty?

The earphones, an OFC cable and four pairs of ear tips. Backed by 14-day cover against product defects with genuine-unit verification and cash on delivery across Egypt.
