Bought this to improve focus while working from home. With all the distractions, concentration can be challenging. This has been incredibly helpful. I run it in my office with focus-enhancing frequencies. Creates a productive atmosphere and my ability to complete tasks has improved dramatically. The sound is subtle—doesn't interfere with calls or work. Compact enough to sit discretely on my desk. Colleagues have been asking about it during video meetings. Very straightforward to use with clear instructions. Valuable addition to my workspace that's significantly boosted productivity.

As someone who's battled anxiety for years and tried everything, this has been revolutionary. Use it during stressful work periods and before sleep. Switching frequencies is simple, and the calming ones really work. Was skeptical about frequency healing initially, but after a week of regular use, my anxiety dropped significantly. Great sound quality and user-friendly design. Headphones enhance the experience, but it works well without them too. Customer service was excellent when I had questions. If you're hesitant, just try it—it's made a real difference for me.

Works exactly as described and well-priced (speaking as a former electronics technician). For those saying there's no sound—you need to plug headphones into the right socket for audio, otherwise it generates an electromagnetic field at the indicated frequency. You don't need headphones to benefit. With headphones, limit to 20-minute sessions, but the electromagnetic field can be used continuously. Well-constructed product. Support team responded immediately to my questions.
