Do I need an amplifier for IEMs under $100?

Most IEMs under $100 are efficient enough to be driven by a phone. However, a dedicated DAC/amp dongle ($20-50) will provide cleaner power, lower noise floor, and slightly better sound. It's a worthwhile upgrade if you already have good IEMs.

Are $80 IEMs really as good as $500 ones from 5 years ago?

In many ways, yes. The advancement of driver technology, manufacturing precision, and competition in the Chinese IEM market has compressed the price-performance curve dramatically. A $80 IEM in 2026 often matches or exceeds the technical performance of a $300-500 IEM from 2020.
