KZ ZS10 Pro
Five drivers per side — a 10mm dynamic plus four balanced armatures — for under fifty bucks is the KZ pitch, and the ZS10 Pro delivers a genuinely fun, energetic V-shaped sound that got a lot of people into IEMs. At 24 ohms and 111dB sensitivity your phone drives it easily; no amp needed. Now the honest part: KZ quality control is a known lottery. Most sets are fine, but channel imbalance and driver failures show up in reviews at a rate you don't see from bigger brands, so buy from a seller with easy returns. The upper treble has peaks that get spicy at volume, the stock cable is thin and tangly (it's a standard 0.75mm 2-pin, so upgrades are cheap), and the accessory kit is bare. As a first IEM or a beater set, it's still an easy yes.

Seventeen dollars gets you Apple's wired earbuds with a small DAC built into the USB-C plug, which is quietly the whole story: they bypass your phone's jack-less design and play at full volume from any USB-C phone, iPad, or laptop — an amp is beside the point, and Apple doesn't even publish an impedance figure. The open, unsealed fit is love-it-or-hate-it: no silicone tips to fuss with and you can hear traffic, but there's zero isolation and bass is thin unless they happen to fit your ears just right. The inline remote and mic are genuinely good — many people keep a pair purely for calls because they beat most Bluetooth mics. Longevity is fine but not endless; the cable survives pockets better than the old 3.5mm version, and at this price they're effectively disposable.
Sony
Sony MDR-7506
The MDR-7506 has been hanging in broadcast booths and video rigs since 1991, and almost nothing about it has changed — including the flaws. At 63 ohms and 106dB/mW it's sensitive enough that any camera, mixer, or phone drives it fine without an amp. The sound is bright and detail-forward: sibilance, hum, and edit points jump out, which is exactly why engineers love it and casual listeners sometimes find it fatiguing. The 230g folding frame is featherweight for all-day wear. Two gripes come up constantly: the 3-meter coiled cable is permanently attached and heavy for desk use, and the stock earpads famously disintegrate into black flakes within a year or two — nearly every long-term owner ends up buying aftermarket pads and considers it part of the price.
Beyerdynamic
Beyerdynamic DT 770 Pro (80 Ohm)
The DT 770 Pro's velour earpads and gentle clamp make it the comfort benchmark among closed studio headphones — people track drums in these for eight-hour days. The 80-ohm version is the sweet spot for home studios, but be honest about power: a phone or thin laptop jack will get it loud-ish, while an audio interface or small amp is what brings the bass control and volume headroom it's built for. The tuning is V-shaped for a monitor: elevated lows, slightly recessed mids, and a treble spike around 8kHz that bothers treble-sensitive listeners. Isolation is excellent for tracking. The build is famously serviceable — every part is replaceable — but the 3-meter cable is hard-wired and non-detachable, which feels dated at this price. Made in Germany and commonly seen still working after 15 years.
