AKG N400 NC

Note: N400 is about to face its end of product life. Akg.com and Harmanaudio.com are already out of stocks, you still may find some leftovers from third-party retailers.

This is a requiem and a lullaby for this very nice TWS set with high overall standards.

I use following 2 wireless IEMs on a daily occasion.


◦AKG N400NC for any needs for noise cancelling and on the go


◦AKG N5005 for high-res Tidal /lossless streaming

I’ve tried LDAC and Aptx Adaptive and found that I have no urgent needs for “ultimate” hi-res wireless quality especially at practical environment for using these sets such as on the flights & public transportations.

—What makes N400 my endgame as TWS?

▶︎Akg’s app that is pretty intuitive, doesn’t require your confidential personal information like latest SoundPeats app do.

▶︎EQ is fully adjustable, you can twist tuning by touch screen, very easy and intuitive.

▶︎Unlike AirPodsPro, you can fully adjust the ANC’s offset phasing, that is crucial functionality especially when you are adopting third-party ear-tips.

▶︎Although N400 isn’t latest blessed sub$100 beast like Moondrop’s LCP princess —Aria 2020—, N400’s hardware spec is par or above long time benchmarked Moondrop’s Starfield. Great enough as you want on non-LDAC or Aptx-HD/Adaptive.

—Any recommendations for the EQ?
Here are some EQ you may try with N400 w/ AZLA Xelastec.

full-time default:
Neutral with huge sub-bass boost


True-neutral for a flat presentation


V-tuned one, for fun


@tgx78 ’s MEST-OG inspired “divine” tuning: crisp and nicely tuned
