So my Etymotic ER4PT cable finally gave up but Etymotic have upgraded the entire ER4 (their top tier / professional line of IEMs).
I thought about just getting a new cable however I thought I might give the new ones a try since the previous pair had survived since 2007, I mean that's a pretty good decade run.
I got the ER4XR, the imaging and resolution is pretty amazing with some great sound stage for IEMs (actually surprising when it happens, sounds closer to an open back headphone for some tracks due to the recording and depending on what I'm using for the source). Build quality is great again, way lighter than before, made of aluminium casings where possible rather than plastic. Just a kick of bass.
With the quality of service and commitment to owners of their headphones, it's great that companies exist who will give their devices services for as long as they produce the earphone (the prior model I had were around from 1991 to 2016, effectively 15 years of support).
Can't speak highly enough of them and the product they produce, plus the prices.
I did consider getting a bluetooth set of headphones but after trying them out the difference in sound and heaviness plus bothering with battery etc is just enough of a hassle to stick with high quality IEMs.
Edit: Just switched some Rage Against the Machine on and it's the first time I can clearly hear every single word that Zach de la Rocha is saying without concentrating. Bopping my head to a song I didn't rate too highly before but now love Snakecharmer.
