Sometimes it is the repetition: another length, another turn and another quiet hour following the black line. That is the problem swim coach and creator TheSwimsuitGuy set out to explore in his sponsored hands-on video, These SollaWave Smart Goggles Replace 5 Pieces of Swim Kit . He took SollaWave into the pool to see how underwater music, in-ear headphones, voice feedback and swim tracking fit into a real session. His test was not about shaving a guaranteed number of seconds from every swim. It focused on a more practical question: can one integrated device make regular pool training simpler and more enjoyable? SollaWave combines swim goggles, underwater audio and training feedback in one device. Image captured from TheSwimsuitGuy’s SollaWave review . One Pair of Goggles, Five Pieces of Swim Kit The main idea behind SollaWave is consolidation. Instead of treating goggles, underwater headphones, earplugs, a swim tracker and anti-fog protection as separate items, the product brings those functions into one piece of equipment. That matters more than it may sound. Every extra item creates another small step before a swim: pack it, charge it, fit it, remember it and make sure it stays in place. An integrated setup reduces that friction. You still need to prepare your audio and charge the goggles, but there are fewer separate parts competing for space around your cap, ears and wrist. The result is not a minimalist pair of racing goggles. At 76 grams, SollaWave carries more hardware than a conventional pair. Its appeal is the trade: a more substantial device in exchange for fewer separate accessories. What Underwater Music Changes During Solo Training TheSwimsuitGuy frames the most compelling use case through his own experience of swimming alone over many years. Repeated solo sessions can become monotonous even when the workout is well designed. Music does not change the distance on the board, but it can change how that distance feels. For steady aerobic work, recovery swimming or a long continuous set, a familiar playlist can help create rhythm. For shorter intervals, swimmers can build playlists around the mood of the session: calmer tracks for warm-up, higher-energy music for the main set and something easier for the swim-down. SollaWave stores audio locally rather than streaming it from a phone. That distinction is important because Bluetooth signals weaken rapidly underwater. Once compatible audio files have been transferred to the goggles, playback does not depend on keeping a phone at the pool edge or maintaining a wireless connection through the water. There is a practical limitation: streaming-library tracks from services such as Spotify or Apple Music cannot simply be played through an underwater Bluetooth connection. Swimmers need to load compatible local audio before the session. It adds a preparation step, but it also removes the dropouts associated with underwater wireless transmission. A real pool test shows how the integrated setup sits in place while swimming. Image captured from TheSwimsuitGuy’s SollaWave review . In-Ear Sound Versus Bone Conduction Underwater Most swim-audio products use either an in-ear design or bone conduction. They solve the same problem in different ways. Bone-conduction devices leave the ear canal open and transmit vibration through the area around the cheekbone. SollaWave instead uses sealed in-ear earpieces that deliver sound directly into the ears. The aim is a more enclosed listening experience with less surrounding pool noise competing with the audio. This does not mean that one format will suit every swimmer. Some people prefer the open-ear feel of bone conduction; others want the isolation and directness of an in-ear seal. Ear anatomy also varies, so tip selection matters. SollaWave includes several ear-tip sizes, and taking time to find the correct fit is part of getting stable sound and comfort in the water. Earphones That Also Work as Earplugs The earpieces perform two jobs. They carry the audio, and their seal also serves the role of swimming earplugs. For swimmers who already wear earplugs, this is one of the most logical parts of the five-in-one concept: the product is not asking them to add another item inside or around the ear. Fit remains personal. The correct tip should feel secure without creating uncomfortable pressure. It is worth testing the setup during an easier pool session before relying on it for a long workout. Push-offs and turns are better tests of stability than standing at the wall. The integrated earpieces deliver audio while also serving as swimming earplugs. Image captured from TheSwimsuitGuy’s SollaWave review . Voice Feedback Without Looking at a Watch Music is only one part of the experience. SollaWave can also provide scheduled audio updates for pool metrics including time, distance, lap count, pace and SWOLF. That changes how a swimmer checks progress. A watch usually requires a glance at the wall, during a rest or while adjusting the wrist into view. SollaWave keeps the feedback in the same audio channel as the workout, so the swimmer can hear selected updates without adding a display in front of the eye. This is an important distinction within the HoloSport range. SollaWave is an audio-first product designed for pool swimming. It does not have an in-lens AR display, built-in GPS or compass navigation. Swimmers who specifically want visual data in the lens or directional support for open water should compare it with HoloSwim 3 Pro . What the Review Makes Clear The strongest part of TheSwimsuitGuy’s test is that the product is shown in the environment where it is supposed to work. The goggles are not only presented on a table; they are fitted, adjusted and used underwater. That real-session context supports three practical takeaways: The integrated concept is the main benefit. Music, ear protection and training feedback do not require three separate devices. Audio is about consistency as much as entertainment. It can give solo swimmers another reason to stay engaged with routine sessions. Fit and preparation still matter. Swimmers need the right ear tips, a comfortable goggle seal, charged hardware and audio loaded before getting in. The review should not be read as a guarantee that every swimmer will prefer in-ear audio or find music useful for every set. Technique-focused work, coached sessions and very short race-pace efforts may demand a different kind of attention. SollaWave makes the clearest case during regular pool training where motivation, rhythm and simple feedback matter. Who Is SollaWave Best For? Based on the use case shown in the video, SollaWave is most relevant for: swimmers who complete a large share of their training alone; fitness and endurance swimmers who find long pool sessions repetitive; people who already use earplugs or underwater headphones; swimmers who want pace, distance and lap feedback without looking at a watch; users who prefer one integrated setup over several separate accessories. It may be less suitable for someone who wants only the lightest possible conventional goggles, does not like an in-ear seal or primarily needs open-water GPS and navigation. HoloSport’s Take From our perspective, the value of SollaWave is not that every swim needs more technology. It is that the right feedback can enter the session without repeatedly interrupting it. HoloSwim products approach that idea visually by putting useful information inside the swimmer’s field of view. SollaWave approaches it through sound. Music supports rhythm and motivation; voice updates provide selected training information; the integrated earpieces reduce the need for separate headphones and earplugs. TheSwimsuitGuy’s pool test demonstrates that difference clearly. SollaWave is not trying to replace coaching, a purposeful workout or the swimmer’s own judgment. It is designed to make the repeated work of pool training easier to stay with. Final Verdict SollaWave makes the strongest case for swimmers who want more engagement from solo pool sessions and who value integrated equipment. Its in-ear audio, local music playback and spoken swim metrics create an experience that is meaningfully different from both standard goggles and standalone waterproof headphones. The tradeoffs are straightforward: music must be prepared in advance, ear-tip fit is personal and the additional hardware makes the goggles more substantial than a conventional pair. For the right swimmer, however, replacing several pieces of kit with one connected system can make the routine simpler—and the time between the walls less quiet.
