I’ve got just about every basshead IEM except the uber expensive Empire Ears Legend X. I have had a hard time figuring out what the actual construction differences are between this and other TFZ IEMs like the No.3 and honestly they sound similar, so I wasn’t expecting an improvement over the No.3 but there’s just a tiny bit more sub bass extension in these, and the highs seem to be just a bit more smoothed out. The vocals are clean, and pronounced which is great to hear. Just with anything, there’s not “one IEM to beat them all” so some songs make these sing and others are just OK. Their strongest is in the electronic music genre. Here are some thoughts based on some song replays:
Simplify by Los Coast: There’s a bass line that rides through the song and it sounds awesome on this set, but there’s a ringing bell in the song that is a bit sharp at times.
Where we Started by Lost Sky: the bass line is impactful and clean clear female vocals make these things absolutely slap.
Bury a Friend by Billie Eilish: This song has an intentional and impactful bass track that is made to invoke a response and these make that song sound amazing.
Savage by Whethan: This song has slower and heavier moments and in the vocal positions, the singer is clean and clear, and when the bass lines come in, they are impactful without overriding the vocals.
Overall these are my new favorite IEMs. There are others like the No.3 and even the VE Bonus IE Pro’s that have impactful bass, but these also have some clean (but recessed) mids and crisp highs.
The texture is not necessarily the best and when you get a seal you can hear the driver flex and crinkle but this is the case with most of the larger DD IEMs.
If you are looking for next level basshead IEMs but dont want to drop a house payment on the EE LX, these will do nicely.
