Best IEMs & Earphones for Nothing Phone 4A Pro in 2025
Looking for the best headphones and IEMs to pair with your Nothing Phone 4A Pro or Nothing 4A? We rank the top wired and wireless options, including budget picks from GK AudioLab and KZ.
Why Your IEM Choice Matters More on the Nothing Phone 4A Pro
The Nothing Phone 4A Pro (and the standard Nothing 4A) ships with a high-quality USB-C audio implementation β one of the better DAC outputs among mid-range Android phones. This means it can actually reveal the quality differences between budget and mid-tier IEMs in a way that lesser phones cannot. Pairing it with the right earphone unlocks its full potential.
Nothing Phone 4A Audio Specs (What Matters for IEM Pairing)
- USB-C audio out: Up to 24-bit/96kHz output via USB-C dongle
- Bluetooth: 5.3 with LDAC support β class-leading for wireless audio quality
- Output impedance: Low enough to drive IEMs in the 16β120Ξ© range without noticeable coloration
Top IEM Picks for Nothing Phone 4A Pro
π₯ Best Overall: GK KUNTEN ($89) β Wired via USB-C Dongle
The GK KUNTEN is the ideal partner for the Nothing 4A Pro's capable USB-C DAC output. The 43Ξ© impedance sits in the optimal range for USB-C dongle power output, and the Super-Linear driver's low distortion reveals the quality of the Nothing Phone's internal DAC beautifully. If you haven't heard a high-quality IEM through a proper DAC chain before, this combination is genuinely revelatory.
π₯ Best Budget Wired: GK X1 ($19)
The GK X1 pairs effortlessly with the Nothing 4A's USB-C output. At 32Ξ© and 110dB/mW sensitivity, it drives to satisfying volume with no dongle amplification needed. The balanced tuning complements Nothing's software EQ presets well.
π₯ Best Hybrid for Nothing 4A: GK G3 ($35)
The GK G3's combined BA+DD driver architecture rewards the Nothing Phone 4A Pro's higher-resolution audio output. The BA driver's treble precision becomes especially apparent when streaming FLAC or high-bitrate Spotify through the phone's DAC chain.
Wireless Option: Nothing Ear (2) or Nothing Ear (a)
If you want wireless and stay in the Nothing ecosystem, the Nothing Ear (2) and Nothing Ear (a) offer tight integration with the Nothing Phone 4A Pro β including dual connection, in-ear detection that pauses the phone's media player, and in-app EQ tuning. For audiophile-priority listening, still recommend wired GK IEMs. For convenience-priority, Nothing's TWS lineup is the natural fit.
How to Use Wired IEMs with Nothing Phone 4A Pro (No Headphone Jack)
Like most 2024β2025 flagship phones, the Nothing Phone 4A and 4A Pro do not include a 3.5mm headphone jack. To use wired IEMs:
- Purchase a USB-C to 3.5mm DAC dongle β we recommend the Apple USB-C adapter ($9), Hiby FC3 ($40), or CX31993-based generic dongles (~$10 on AliExpress)
- All GK AudioLab IEMs use detachable 0.78mm 2-pin cables β you can upgrade to a balanced 4.4mm cable for higher-end dongle DACs if desired
- No software changes needed β the Nothing Phone 4A automatically routes audio to USB-C when a dongle is connected
Final Recommendation
The Nothing Phone 4A Pro deserves a great IEM. Our top pick is the GK KUNTEN for wired listeners β it extracts the most from the phone's excellent USB-C DAC output. For those who want to stay wireless, the Nothing Ear (2) offers the tightest ecosystem integration. Either way, your audio experience on the Nothing 4A is a big step up from stock earbuds.
