I picked up the 700‑yen Aluminum Wireless Earphone at Daiso Kyoto Shijo-dori store because I wanted a sub device for background listening during work. After testing it with both my PC (ThinkPad T14) and smartphone (Android), my impression is that it performs more than adequately for its price. It’s a practical option for anyone who needs a low‑risk, easy‑to‑use backup earphone.
■ First Impressions
The aluminum housing looks modest—neither premium nor poorly made. The controller buttons are oversized and feel cheap, but the overall usability is decent. Build quality aligns with what you would expect from a 700‑yen product.
■ Pairing and Usability
Pairing was smooth right out of the box, likely because it already had some charge. Both PC and smartphone connected without any issues. The Type‑C charging port includes a protective cap, which is uncommon at this price. However, once closed, the cap is surprisingly hard to open, so leaving it slightly open may be more practical.
■ Sound, Latency, Call Quality
The sound is balanced for the price—no excessive bass, and perfectly fine for background music. Video playback does show some latency, which is expected from a non–low‑latency earphone. Call quality is slightly muffled but usable for basic conversations or meetings.
■ Fit and Comfort
Comfort is average. It fits fine for daily work or walking, but not secure enough for running or exercise. There is no noticeable discomfort during longer sessions, but nothing exceptionally comfortable either.
■ Battery Life
The manufacturer claims around 7 hours of playback time; this is still under testing. At the very least, it handles several hours of work without any issues.
■ Overall Verdict
For 700 yen, it’s a surprisingly usable earphone. It’s ideal for people who want a sub device they won’t feel bad about losing. While my main earphones sound noticeably better, this Daiso earphone works perfectly for light tasks and background use.
