Music is a form of art which has been enjoyed by many people since Antiquity. Technological progress has enabled us to hear our favorite songs wherever, whenever and at whatever level we want through portable personal stereos for long periods of time. The aims of this study were to characterize the hearing habits of personal stereo users, without hearing complaints and to correlate the hearing habits and the audiological findings of these adults. Methods: 85 adults (54 females and 31 males), ages between 18 and 34 years, without occupational noise exposure, and personal stereo users participated in this study. They answered a questionnaire about hearing habits and had their hearing evaluations performed at the Federal University of São Paulo. The procedures included: Pure Tone Audiometry; High-frequency Audiometry; Immitance measures; Transient Evoked Otoacoustic Emissions (TEOAE) and Distortion Product Otoacoustic Emissions (DPOAE). Results: Study participants are exposed for more than two hours daily to music presented through headphones for more than four years, usually by transport. The trouble understanding the speaker in a noisy environment increases proportionally to the increase of environment noise and twenty-one subjects reported having tinnitus. The majority is worried about hearing health and believes that bad habits can damage their hearing. There was a 6 kHz notch in the delineation of audiometric configuration from the average hearing thresholds which is characteristic of Noise Induced Hearing Loss (NIHL). Most individuals who claimed to have tinnitus use headphones for over 5.1 years. There was a higher percentage of individuals who use headphones in the ear canal and the thresholds of 12 kHz above 25 dB. Conclusions: The results of this study showed that, although individuals did not show hearing complaints, issues related to noise exposure were observed, such as tinnitus and stress, reflecting the difficulty in understanding speech in noisy environments. Campaigns to prevent hearing damage that focus psychological and social consequences it can cause had an important role in increasing public awareness, especially in younger population
