For EFL students, vocabulary is a fundamental component of learning English. Good vocabulary mastery is essential for improving language skills, such as reading, writing, listening, and speaking. In the digital era, technology offers innovative approaches that can be adapted to various student learning styles. However, previous studies tend to focus on the use of technology in general without linking it to students' different learning styles. This study aims to describe the types of digital technology used by students as well as identify the use of digital technology against its suitability for different students' learning styles. This research used a qualitative method and a descriptive research design. The researcher used observation, questionnaires, and interviews as data collection techniques. The participants were 25 eighth-grade students of the 2024/2025 academic year at SMPN 44 Semarang, selected based on purposive sampling. The finding of this study is that there are many types of digital technology used by students in vocabulary learning, such as Smartphones, YouTube, Word wall, PowerPoint, Google Assistant, Canva, interactive quizzes, Word Office, e-books, and online dictionaries which play an important role in improving vocabulary mastery. Based on the analysis, 9 students have visual learning styles, 6 have auditorial learning styles, 6 have read-write learning styles, and 4 have kinesthetic learning styles. Each learning style shows different technology preferences: visual students are more suitable with technologies such as videos on YouTube, social media, PowerPoints, and digital images; auditorial students with songs on Spotify and podcasts from YouTube and interactive discussions; read-write students with interactive quizzes, digital text, Google Assistant, AI applications, and online dictionaries; and kinesthetic students are more suitable for using practice games from word wall, and interactive presentations.
