ISOVOX

ISOVOX is a Swedish company that manufactures portable vocal isolation booths designed to provide professional recording quality in any environment without requiring acoustic treatment of the surrounding room. The company's flagship product, the ISOVOX 2, is a compact, enclosed booth that sits on a desk or table and surrounds the performer's head and microphone, creating an isolated acoustic environment that eliminates room reflections, echo, and ambient noise from recordings. For actors, particularly those working in voiceover, audiobook narration, ADR, and any application where clean dialogue recording is essential, ISOVOX provides a practical solution that delivers studio-quality audio from a bedroom, apartment, hotel room, or any other untreated space. The product was born from the frustration of professional musicians and voice artists who needed consistent recording quality across different environments without the expense and permanence of building a dedicated vocal booth. ISOVOX has been adopted by professional voice actors, Grammy-nominated musicians, podcasters, and content creators worldwide who value its combination of portability, effectiveness, and professional-grade acoustic isolation. The booth represents a fundamentally different approach to acoustic treatment — rather than treating the room, ISOVOX treats the recording position itself.

The ISOVOX 2 achieves its acoustic isolation through a combination of dense acoustic foam lining the interior of a rigid shell that is shaped to surround the performer's head and microphone from all directions except the open entry point where the performer positions themselves. The interior foam is specifically tuned to absorb the frequency range of the human voice, with particular attention to the mid-range frequencies where dialogue intelligibility resides, resulting in recordings that sound clean and dry without the boxy coloration that can affect some portable isolation products. The rigid outer shell provides a degree of mass-based sound blocking in addition to the absorption provided by the foam, reducing the amount of external noise that reaches the microphone. The design allows the performer to position their head inside the booth comfortably while maintaining enough space for natural head movement during performance, which is important for voice actors who need physical freedom to deliver expressive, dynamic reads. The booth accommodates most standard microphone setups including large-diaphragm condenser microphones on shock mounts. Ventilation is designed to prevent the buildup of heat and humidity that can become uncomfortable during extended recording sessions.

Portability is central to ISOVOX's design philosophy, and the booth is engineered to be lightweight and travel-ready despite its rigid construction. The ISOVOX 2 weighs approximately 15 pounds, which is light enough to transport in a car, check as airline luggage in its optional travel case, or carry to a temporary recording location. The booth requires no assembly — it is a single unit that is placed on a surface, and recording can begin immediately. This contrasts with many portable acoustic solutions that require setup, hanging, or configuration before use, making ISOVOX the fastest path from arrival at a location to a professional-quality recording. For traveling voice actors who work from different locations throughout the year, the ISOVOX 2 provides consistent acoustic quality regardless of the room they are recording in, eliminating the variable of room acoustics from their workflow entirely. The booth can be stored on a shelf, in a closet, or under a bed when not in use, making it practical for actors who live in small apartments. The compact footprint means the booth takes up minimal desk space during use.

The acoustic performance of the ISOVOX 2 has been validated by professional recording engineers, voice actors, and musicians who have compared recordings made inside the booth to recordings made in professionally treated studios and found the quality to be comparable for vocal applications. The booth effectively eliminates the room reflections that are the primary culprit in making home recordings sound unprofessional, producing a clean, dry signal that can be processed, mixed, and mastered to professional standards. For actors recording self-tape dialogue, voiceover demos, audiobook chapters, or ADR lines, the difference between recording with and without the ISOVOX is immediately audible and represents a significant quality improvement. The booth's isolation also works in reverse, reducing the amount of sound that escapes into the surrounding environment, which is a meaningful benefit for actors in apartments or shared living situations where recording volume can disturb neighbors or family members. This bidirectional isolation makes it possible to record at full performance volume without self-censoring, which is essential for authentic voice acting that requires emotional range and dynamic expression. The consistent acoustic environment also means that recordings made across different sessions will match in tone and quality, which is important for audiobook and serialized content projects.

ISOVOX has cultivated a strong reputation within the professional voice acting and music recording communities, with endorsements from working professionals who rely on the booth for their daily recording work. The company's focus on a single product category — portable vocal isolation — has allowed them to refine and optimize the design through multiple iterations based on user feedback from professional recording applications. The ISOVOX community shares recording comparisons, setup tips, and workflow optimizations that help new users maximize the booth's performance. For actors considering a transition into voiceover work, the ISOVOX 2 paired with a quality microphone and audio interface provides the foundation for a complete home studio that can produce commercially viable audio without any room treatment. The booth has been used to record voiceover for commercials, animated series, video games, and audiobooks that have been distributed through major platforms. The Swedish design aesthetic means the booth looks clean and professional in any setting, which can be a consideration for actors who use their recording space for video calls and virtual auditions in addition to audio recording.

The ISOVOX 2 is priced at approximately $600 to $700, which positions it as a premium portable isolation solution significantly more expensive than acoustic blankets or foam panels but dramatically less expensive than constructing a permanent vocal booth. Optional accessories including a travel case, mounting hardware, and replacement foam panels are available at additional cost. The investment is substantial for actors who are just beginning to explore voiceover work, but for working voice actors who record daily, the per-session cost becomes negligible over the life of the product, which is designed to last for years of regular professional use. Compared to renting studio time for voiceover recording, which can cost $50 to $200 per hour in major markets, the ISOVOX pays for itself within a few dozen recording sessions. The one-time purchase with no ongoing costs contrasts favorably with the cumulative expense of studio rentals, and the convenience of recording at home in the booth at any time of day or night provides additional value that is difficult to quantify. For actors who are serious about voiceover as a revenue stream, the ISOVOX 2 is a professional investment that enables a sustainable home recording business.

ISOVOX is highly recommended for working voice actors, actors building a home voiceover studio, and any performer whose career involves regular audio-only recording where clean, professional-quality dialogue is essential. The booth is particularly valuable for actors in urban environments where ambient noise, thin walls, and acoustic reflections from hard surfaces make professional recording challenging without some form of isolation. For actors exploring voiceover as a secondary revenue stream alongside on-camera and theatrical work, the ISOVOX provides the acoustic foundation for a commercially viable home studio when paired with a quality microphone and interface. If your primary need is recording self-tape video with audio, the ISOVOX addresses only the audio component and would need to be used in conjunction with a separate recording setup for the video portion. Actors who are unsure about their commitment to regular audio recording should consider starting with more affordable acoustic treatment options like blankets or panels and upgrading to an ISOVOX once their recording volume justifies the investment.

Position the ISOVOX on a sturdy desk or table at a height that allows you to sit or stand comfortably with your head centered in the booth, as ergonomic positioning is essential for extended recording sessions and optimal acoustic performance. Pair the booth with a large-diaphragm condenser microphone on a desk stand or boom arm that positions the mic at the center of the booth's interior, where the acoustic treatment is most effective. Record a test session immediately after setting up and compare the audio quality to recordings made without the booth, as hearing the dramatic difference will inform how you use the booth going forward and validate your investment. Keep the booth accessible and ready to use rather than storing it away between sessions, as the convenience of being able to record at any moment is one of its primary advantages over studio-based recording. If you experience warmth or discomfort during long sessions, take regular breaks and consider positioning a small fan outside the booth to promote air circulation through the opening. Use the consistent acoustic environment to your advantage by establishing a standard microphone position, gain level, and recording chain that you maintain across all sessions, ensuring that your recordings match in quality and tone regardless of when they were made.
