In a crowded true wireless earphone market, QCY has built a reputation for delivering remarkable performance at budget-friendly prices. The company’s new flagship model, the MeloBuds N70, continues that tradition — priced under $70, featuring a USound MEMS driver.

According to Yoshihiro Sasaki, the MeloBuds N70 are the first mainstream true wireless earbuds to incorporate USound’s MEMS driver, and it does so within a hybrid architecture that pairs a dynamic driver for low and mid frequencies with a MEMS driver for the high range. Both drivers are integrated into a single audio module, Greip, developed by USound, engineered specifically for this hybrid configuration.

The result is a sound signature that exceeds expectations for its price:

“Bass is strong yet tight, mids remain clear, and highs are sharp and extended without harshness. Especially in the upper midrange, the MEMS driver delivers a level of clarity and resolution rare even among more expensive models.”

The reviewer notes that the adaptive ANC system performs effectively in everyday environments, reducing train noise while preserving vocal intelligibility, and praises the N70’s extensive feature set, including multipoint connectivity, in-ear detection, and a Japanese-language companion app.

After experimenting with different eartips to optimize fit and acoustics, Sasaki concludes that the MeloBuds N70 is not just an impressive low-cost option but a product worthy of daily use:

“What began as an experiment to test a new technology ended up becoming my main pair of TWS earphones. USound’s integrated MEMS driver elevates the N70’s sound quality far beyond what its price would suggest.”
