Full-size gaming headsets have long been a popular choice for most gamers. IEMs (in-ear monitors), on the other hand, have traditionally been overlooked. While traditional headsets like the Logitech G Pro X 2 provide an immersive audio experience, the clamping force, weight, and bulkiness can make them uncomfortable for some people. This is where IEMs come in.
The term IEM traditionally refers to any in-ear earphone, but it usually implies an enthusiast-grade, wired model. IEMs are tiny, lightweight, and pack a punch! And just because they’re enthusiast-grade, they don’t necessarily have to cost an arm and a leg.
The linked article makes some very good points, especially too when it comes to the weight and bulk of headphones when wearing them for many hours.
A very important question to ask is: Why do you really want the device? Don’t just buy headphones because they are cool looking and seem popular. I made that mistake myself when buying a gaming chair – after about 3 years it was no longer comfortable at all (the seat wears flat) and they’re actually not very ergonomic. I eventually tossed out my gaming chair and replaced it with a very good, ergonomic office chair with a 10-year warranty.
Rather buy for quality and comfort, and it will probably last much longer and also be far comfier to wear.
So, yes for IEMs a potential downside to consider is whether you need a microphone, as that can often be a shortcoming with IEMs.
