Welcome to my review of the Alpha & Delta JAPP Wireless Sports Earphones Review. These wireless earphones are named after the inventor of Bluetooth, Jaap Haartsen. They retail for $90.
Alpha & Delta designed the Jaap is to overcome the existing problems that plagued truly wireless earphones namely: poor fit, poor battery life and poor connectivity.
First up they feature a behind-the-ear hook design which ensures it stays secure during workouts. I even tried shaking my head to make them fall off, and they didn’t. The tips are using the patented SpinFit bud which is amazing from a comfort and sound quality point of view. They are also IPX5 sweat resistant, so ideal for working out.
The battery life is 6 hours plus the supplied battery bank/charger provides another 8 hours.
In terms of connection, I never lost a beat. Each earphone feature a dual antenna design. To start you pair the left side and then turn on the right earphone, which pairs automatically with the left. Neat.

In use, the earphones fit really well and their design is also comfortable, despite its size. I felt the charging solution felt a bit cumbersome but it works well. It is also nice that a carry case to hold everything is included.
The sound quality is pretty good as the SpinFit earbuds provide a solid seal in the ears. Treble is controlled and bass fairly deep. Mids are reasonably clear too. Average soundstage but overall these are a pleasure to listen to music with for extended periods of time.
Despite their larger size, the Alpha & Delta Wireless Sports Earphones sound good with decent bass, fit securely and comfortably and are recommended.
