Crinacle is one of the reference measurers in personal audio: he publishes frequency-response curves for hundreds of headphones. An IEM co-developed with him starts from a target curve justified with data rather than from whatever sounds flashy in a shop demo. That's why this model became the default recommendation at its price.
An in-ear seals the ear canal, so it isolates far more than any closed cup. At a LAN or in a noisy house, that means hearing footsteps that an open or semi-open headset loses. It's the reason a good share of professional CS players compete with IEMs under a pair of isolating earmuffs.
Two dynamic drivers, 10 and 7.8 mm, instead of mixing a dynamic with balanced armatures. The advantage is coherence: the two driver types have different response times and marrying them well is hard and expensive. With two well-integrated dynamics the result is more homogeneous, which is exactly what you want for locating sounds.

| Careful, this isn't a headset | It's an in-ear monitor with no microphone: to talk you'll need a separate mic, desk or cable-mounted |

Fields with no data show as “—”: it means neither Amazon nor the manufacturer publishes that figure. We'd rather leave it empty than estimate it.
It's the most serious audio option on the list under 70 dollars, with treble detail — where footsteps live — that no headset at this price reaches, and with far better isolation. The catch is big: no microphone, so you need a separate one to communicate.
It sounds very good and isolates, though in a game where audio is secondary the argument counts for less. How comfortable an in-ear is over hours depends a lot on your ears and the tips you use.
Excellent sound quality for long sessions, and very light. Since it has no microphone, if you play on a server with voice chat you'll have to solve that elsewhere.
Good sound, but for Roblox, where voice chat is the norm, a mic-less IEM complicates more than it adds. A Cloud III is more practical for that use.
Ideal for: Someone who wants the best sound and isolation under 70 dollars and already has a separate microphone.
It has 1,625 reviews at a 4.3 average, a very solid base for a niche product. What usually recurs in this model's opinions is that it delivers a level of sound you don't expect at the price; the standard complaint with any IEM is the fit in your ear, which is personal.
