Sennheiser IE 400 Pro SBK

Comfortable and sounds good

Treble is a little high but not a bad thing. Overall still good tuning and balance. Easy to wear but not very easy to take out. Isolation is very good. Case is a good inclusion in the package. Currently using for DJ monitoring and mix referencing.

Impressive - worth the money

I have been totally captured by the sound quality of these in ear monitors. The single drive performs with balance, control and personality. Sennheiser themselves describe these like "punchy" in ear monitor, but, subjectively, their punchiness is never disproportionate nor too colorful. They got the guts when required and only when required. I'd definitely recommend to replace the silicon tips with the foam ones (included) as they delivered a significant improvement in terms of sound isolation and comfort. And yes, they made in EU.

Really solid in-ears

With the included foam tips sound insulation is nigh on perfect, while the rubber tips let a bit more through.

Really distinct bass and great sound overall.

When it comes to comfort, if wearing them for only a few hours a day they're totally fine, but after having them in my ears +8hrs/day for multiple days the plastic starts scratching up your ear. You might have better luck with different shaped ears, but for me I have to reserve them for use on the move and use my DT990 Pros as my day-to-day monitors.

In terms of production quality I've had no issues in a little over half a year of usage.
