If you want over-ear wireless headphones for computer calls, focused listening, and everyday use, choose TREBLAB Z2; if you need swim-ready goggles with offline music and training feedback, choose Holoswim SollaWave AI Music. For a computer, I’d choose the TREBLAB Z2 because its Bluetooth and 3.5 mm connection suit ordinary desk setups. The SollaWave is purpose-built for the pool, not a general computer headset.
TREBLAB Z2 vs Holoswim SollaWave AI Music at a Glance
• TREBLAB Z2 strength: Over-ear Bluetooth headphones with hybrid active noise cancellation, multipoint Bluetooth 5.3, a 3.5 mm jack, and up to 58 hours of battery life. Trade-off: Its button controls and over-ear form are less suited to swimming.
• Holoswim SollaWave AI Music strength: Swim goggles with offline music, swim tracking, and in-app AI analysis. Trade-off: Music playback is designed around downloaded MP3 files, not ordinary Bluetooth streaming.
• For a computer: TREBLAB Z2 is the practical choice for desk listening and calls, with Bluetooth or a wired connection.
• For pool training: SollaWave combines goggles, audio, and swimming metrics in one system.
• Choose TREBLAB Z2 for everyday listening and computer use; choose SollaWave for swimming workouts and feedback.
The TREBLAB Z2 is a conventional over-ear wireless headphone with features that make sense across a desk, home, or commute. Its Bluetooth 5.3 connection supports wireless use, while the 3.5 mm jack gives you a wired option when that better suits your computer or another audio source. A listed Bluetooth range of 33 feet offers room to move around without staying right beside the connected device, though walls and setup can affect any wireless connection.
Hybrid active noise cancellation is the standout feature for listeners who want to reduce surrounding sound while concentrating. The controls are physical buttons rather than touch surfaces, and the headphones also list voice control support for Google Assistant. That makes the Z2 a straightforward fit for someone who prefers pressing a button to find a control, rather than learning a touch gesture. A 40 mm dynamic driver and a stated frequency range of 20 Hz to 20,000 Hz describe its audio hardware, but they do not by themselves establish how it will sound to every listener.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
For a computer, the Z2 makes more sense than swimming headphones: it offers ordinary Bluetooth connectivity and a headphone jack, with a stated 65-millisecond latency figure for its gaming mode. Multipoint Bluetooth 5.3 is also listed, which is useful if you want to connect with more than one compatible device. The battery is listed at up to 58 hours, with a three-hour charge time, so it is designed for long stretches between charges. Its foldable design and included carrying case add a practical way to pack it away. IPX4 sweat resistance is a modest added safeguard, not a reason to treat it as swimming gear.
Who should skip it: Skip the Z2 if you need waterproof headphones for swimming, swimming metrics, or goggles with integrated audio.
The Holoswim SollaWave AI Music is not simply an alternative pair of everyday headphones. It is a swim-focused system built around goggles, in-ear audio, offline music, and motion tracking. The product is listed as IP68 waterproof and uses an isolated audio module. Its sensors and swim algorithm are intended to track measures such as time, distance, laps, pace per 100 meters, SWOLF, and stroke type. If your goal is to add structure to pool sessions, those features make it a much closer fit than general over-ear headphones.
Music works differently here. The SollaWave is designed for offline playback from its built-in 4 GB MP3 player, with capacity described as up to 800 songs. The product explanation says Bluetooth audio is unreliable underwater because water absorbs 2.4 GHz signals, so the intended approach is to load music for offline listening instead of streaming from a phone during a swim. That is a meaningful trade-off: it can keep music independent of an underwater Bluetooth link, but it is not the easy choice for streaming computer audio or taking calls.
After a session, the product syncs swim data to an app, where it presents training information and AI analysis. Its battery specification lists up to eight hours of music playback or up to 80 hours in swim voice-feedback mode. Those are different modes, so the longer figure should not be mistaken for music playback time. The goggles also list fog-resistant lenses, an adjustable fit system, and replaceable components. This package is best for someone who swims regularly and wants audio and workout information together, rather than someone shopping for a versatile headset.
Who should skip it: Skip SollaWave if your main need is wireless computer audio, Bluetooth music streaming, or a general-purpose headset for work.
Side-by-Side: Which Should You Choose?
• Best for computer listening → TREBLAB Z2. Bluetooth and a 3.5 mm jack give it two ways to connect to compatible computer setups.
• Best for swimming workouts → Holoswim SollaWave AI Music. It is built as swim goggles with IP68 waterproofing and swimming-specific tracking.
• Best for swimming metrics → SollaWave. Its sensors track swim measures including distance, laps, pace, SWOLF, and stroke type.
• Best for offline pool music → SollaWave. Its 4 GB MP3 player is intended for downloaded listening while swimming.
• Best for longer stated music playback → TREBLAB Z2. Its battery is listed at up to 58 hours, compared with up to eight hours of SollaWave music playback.
• Best for a wired connection → TREBLAB Z2. It includes a 3.5 mm headphone jack; SollaWave has no jack.
• Best for touch-control shopping → Neither is a clear match. The Z2 uses buttons, while SollaWave lists app control. If you specifically want the best touch control over ear headphones for computer, these specifications do not describe either product as a touch-controlled over-ear model.
The first question is not which product has more features. It is where you plan to use it. If you want headphones beside a laptop for calls, videos, or general listening, the Z2’s over-ear form and standard Bluetooth connection are aligned with that job. Its wired jack can also help when you want to connect directly to a computer that has a compatible headphone output. The SollaWave is designed around a very different situation: wearing goggles in the pool and listening to music stored on the device.
Think carefully about what “wireless” means for your routine. The Z2 uses Bluetooth for ordinary device connections and also offers a wired alternative. The SollaWave has Bluetooth listed, but its swimming music feature is offline MP3 playback; it should not be chosen on the assumption that it will stream reliably from a computer or phone underwater. If you are searching for ear clip headphones for computer or open ear earbuds for computer, neither product matches those categories: one is over-ear, and the other is an in-ear audio system integrated with swim goggles.
Control preferences matter, too. The Z2 has push-button controls, while SollaWave lists app control and provides swim feedback as part of its training concept. Neither is described as a touch-control over-ear headset. Battery figures also need context: Z2’s stated up-to-58-hour battery life is a single general figure, while SollaWave separates up-to-eight-hour music playback from up-to-80-hour voice-feedback mode. Those figures refer to different uses, so they are not directly interchangeable.
Finally, consider the trade-offs that come with each design. Z2 is a general listening product with ANC, a carrying case, and a foldable form, but its listed IPX4 resistance does not make it a swimming headphone. SollaWave is purpose-built for pool sessions, including waterproofing and swim data, but its offline music method and training-focused controls make it a poor substitute for a typical computer headset. If ownership terms or current price affect your choice, check the current product details before deciding; the feature differences are the stronger guide to which one fits your actual routine.
In my opinion, I’d buy the TREBLAB Z2 for a computer because its over-ear design, Bluetooth, 3.5 mm jack, ANC, and long stated battery life fit everyday desk listening more naturally. I would choose SollaWave only if swimming is the main use and I wanted offline music plus swim analysis in the same system. They solve different problems, but for general listening at a computer, the Z2 is the clear fit.
The Z2 supports Bluetooth and has a 3.5 mm headphone jack, so it can connect wirelessly or through a compatible wired audio connection. Which option works best depends on the computer’s connections and setup.
Its swimming music feature is designed for offline playback from the built-in MP3 player. The product description explains that Bluetooth audio is unreliable underwater, so it is not presented as a dependable way to stream computer audio in the pool.
The TREBLAB Z2 lists hybrid active noise cancellation. SollaWave lists no noise control, and its design is focused on swimming audio and training rather than reducing everyday background noise.
The Z2 is listed at up to 58 hours. SollaWave lists up to eight hours for music playback and up to 80 hours for swim voice-feedback mode, so the longer SollaWave figure applies to a different use than music listening.
