Introduction
As somebody that’s passionate about music, I prefer a very specific combo: in-ear type earphones with a portable amp. The reason is simple, if audio is your number one priority, this combo easily outperforms any other setup. An added bonus is the fact that in-ear earphones basically act like earplugs, passively providing lots of sound isolation.
As always, there’s a catch: this setup isn’t that very portable or convenient: In-ear earphones, usually called In-ear-monitors or IEM require a tight seal in order to perform, requiring the need to be placed uncomfortably deep inside the ear-canal. For this reason they also require constant cleaning and it’s also the reason why IEM are not something you could share with others.
Another difficulty comes from the fact that you need to put them in correctly, requiring specific techniques like slightly opening the jaw or moisturizing the sleeves. Many first-time IEM buyers usually don’t know about these techniques and end up with a subpar listening experience. They are extremely effective at blocking out all sounds, meaning that throughout the day you’ll find yourself constantly taking them out just to have a normal conversation. Lastly, there’s also the issue with wires and lugging around an amp isn’t my idea of fun. I needed something more practical which brought me to the Nokia BH-905 and the updated BH-905i. Armed with almost $500 worth of 905 goodness I set to answer the question: IEM (Shure SE535 and SE425), 905 or 905i?
