• Konnek Stein True — biggest strength: true active noise cancellation with a rated 90% background-noise reduction, plus a 500mAh sliding case that recharges the buds about four times.
• Konnek Stein True — biggest trade-off: IPX4 only. Splashes and sweat are fine; swimming is not, and 5 hours per charge is modest.
• Clooissr IPX8 — biggest strength: IPX8 water rating, submersible to 6 m (20 ft), with a built-in MP3 player holding 1,500+ songs so music keeps playing where Bluetooth cannot reach.
• Clooissr IPX8 — biggest trade-off: passive noise cancellation only, and the underwater tuning trades heavy bass for clarity. It also wants a swim cap over it for the most secure fit.
• Who Konnek Stein True is for: commuters, office and gym users who want quiet and a normal touch-control earbud.
• Who Clooissr IPX8 is for: swimmers and water athletes who want music in the pool without a phone nearby.
Konnek Stein True is built around one idea: block the noise around you. Each earbud runs an active noise cancellation mode that detects outside sound and cancels it, which the spec sheet puts at up to 90% of background noise. That is the headline feature, and it is the reason to pick this pair over a passive design. On a train, in an open-plan office, or next to a treadmill bank, that is the difference between hearing your music and hearing the room.
Fit gets real attention too. The 30° angled in-ear design with rounded silicone tips comes in S, M and L, and the guidance is to nudge the bud slightly into the canal after wearing it, which also helps the noise cancelling do its job. The trade-offs are clear: IPX4 covers sweat and accidental splashes, not submersion, and about 5 hours per charge means you top up from the case most days. If you want earbuds for the pool, skip this one. If you want a quiet commute and a comfortable all-day bud, this is the fit.
Clooissr IPX8: Who It's For
Clooissr IPX8 is a specialist tool, and it is unapologetic about it. The IPX8 rating means it is submersible to 6 m (20 ft), which covers pool laps, open-water swims and everyday training. The important detail is the mode switch: Bluetooth signals do not travel through water, so you flip to MP3 mode and the built-in player keeps going. Storage handles 1,500+ songs in MP3, FLAC and WMA, and you load music over the included USB data cable from a PC or Mac. No phone on the pool deck, no signal dropouts.
Fit is engineered for movement. The 30° rotatable ear hooks and soft silicone body are shaped for swimming rather than sitting at a desk, and three sizes of swim-specific tips (S/M/L) let you build a proper seal — which matters twice over, because a good seal improves both comfort and sound. Clooissr also recommends wearing a swim cap over the headphones for the most secure hold during flip turns and hard sets, which is a fair trade for staying put in the water.
The audio is tuned for underwater acoustics: 12mm dynamic drivers that stay clear and undistorted instead of chasing heavy bass. Noise control is passive, not active — a deliberate choice, since a sealed swim fit already shuts out a lot. Battery is generous at up to 12 hours, with roughly 10 hours in Bluetooth and 8 hours in MP3. Two quirks worth knowing: playback order may reset after a full power-off, and you navigate tracks with long-presses on the volume buttons. This is not the pair for a quiet office. It is the pair for the water.
Side-by-Side: Which Should You Choose?
• Best for noise cancelling → Konnek Stein True. Active noise cancellation rated to cut around 90% of background noise; Clooissr uses passive isolation.
• Best for battery life → Clooissr IPX8. Up to 12 hours total, with 10 hours Bluetooth or 8 hours MP3, against about 5 hours per charge on the Konnek Stein.
• Best for phone-free music → Clooissr IPX8. The built-in MP3 player, 1,500+ songs and 8GB storage mean no handset required.
• Best for commuting, office and calls → Konnek Stein True. Bluetooth 5.1, touch controls, Siri activation and a sliding case that recharges the buds around four times.
• Best for secure in-water fit → Clooissr IPX8. Rotatable ear hooks plus swim-specific tips, worn under a swim cap.
• Best for everyday, all-purpose listening → Konnek Stein True. A conventional in-ear design with S/M/L silicone tips and a bass-forward tuning.
• Best for long, stationary sessions → Clooissr IPX8. The longer runtime and soft cable-free hooks suit extended wear.
If I had to choose one, I would buy the Clooissr IPX8. In my opinion it covers more ground: it swims, it survives rain and sweat, it plays from its own memory when Bluetooth cannot, and it lasts roughly twice as long per charge. The Konnek Stein True is the better pick if active noise cancelling is your priority and you never go near the water — but for most people who want one pair that handles the pool, the trail and the commute, I recommend the Clooissr IPX8.
