How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a sliding charging case with a genuinely pocketable, familiar-feeling set of ANC earbuds and you mostly care about sweat-proof gym and commute use, choose Konnek Stein True; if you need longer total playtime, a newer Bluetooth generation, app-based EQ control and a 6-mic call setup for meetings and travel, choose Alpsnd Pro.
• Konnek Stein True — biggest strength: Active noise cancellation rated to cut up to 90% of background noise, a sliding 500mAh charging case that can recharge the buds about four times over, and Bluetooth 5.1 with a 10-meter range.
• Konnek Stein True — biggest trade-off: Roughly 5 hours of music playtime per charge, and a single 10mm dynamic driver means you get its bass and clarity tuning, not a customizable one.
• Alpsnd Pro — biggest strength: Up to 20 hours of playtime, Bluetooth 6.0, a 13mm dynamic driver, app EQ control and a 6-mic ENC call system rated to cut up to 97% of background noise.
• Alpsnd Pro — biggest trade-off: No IP rating beyond IPX4 and no ear hooks, so the fit relies entirely on the tips and shell; battery life is listed as up to 20 hours total rather than per-charge.
• Who each pick is for: Konnek Stein True for the buyer who wants a compact, slide-open case and strong noise reduction on a budget-conscious ANC set; Alpsnd Pro for the buyer who wants more runtime, app tuning and better call clarity for work and travel.
The Konnek Stein True is built around one clear idea: block out the world and keep the case small. Each earbud runs its own active noise cancellation mode that the spec sheet says can reduce up to 90% of background noise before it reaches your ear canal. That is a meaningful figure for a set aimed at business and sport use — it is the kind of reduction that makes a difference on a bus, in an open office, or on a treadmill next to a fan. The sound signature leans toward strong bass with what the listing calls crisp highs, which suits pop, hip-hop, electronic and most gym playlists.
Who should buy it: someone who wants active noise cancellation in a small, sliding case, values a secure in-ear fit with S/M/L silicone tips, and mostly uses earbuds for commuting, jogging, yoga, hiking and home office calls. Who should skip it: if you want per-earbud battery that stretches toward a full day, app-level EQ tweaking, or the newest Bluetooth generation, the Alpsnd Pro covers those ground better. If your priority is the deepest possible bass from a larger driver, the 10mm driver here is the smaller of the two.
Alpsnd Pro: Who It's For
Alpsnd Pro goes after the all-day user. The headline numbers are 20 hours of playtime, Bluetooth 6.0 and a 13mm dynamic driver — the largest driver in this comparison — which the listing pairs with app-based EQ control so you can tilt the sound toward bass, vocals or a flatter profile depending on what you are listening to. The ANC is rated to reduce noise up to 50dB, and the call side uses a 6-microphone ENC system that the description says cuts up to 97% of background noise. In plain terms: this is a set designed for people who take calls in noisy places and want their voice to come through.
Comfort is handled with a lightweight in-ear shell and soft ear tips in three sizes, deliberately without ear hooks. That keeps it low-profile for sleeping on a plane or wearing under a hat, but it also means fit depends on getting the tip size right — there is no hook to fall back on. The case includes an LED power display so you can see the remaining charge at a glance, and the companion app handles EQ settings, touch customization and other controls. A 1-hour charge time is listed, and the package includes the case, the earbuds, a USB-C to USB charging cable, three tip sizes and a manual, with a 1-year manufacturer warranty.
Who should buy it: commuters, students, remote workers and frequent flyers who want long runtime, app tuning, low-latency audio for gaming and streaming, and strong call clarity. Who should skip it: if you prefer a physical hook or wing for maximum stability during hard workouts, or you want the sliding-case form factor, the Konnek Stein True is the closer match. The plastic enclosure and in-ear shape here are conventional rather than ruggedized beyond IPX4.
• Best for total playtime → Alpsnd Pro. Up to 20 hours versus roughly 5 hours per charge on the Konnek Stein True.
• Best for battery backup in the case → Konnek Stein True. Its 500mAh case can recharge the buds about four times over after one full charge.
• Best for call clarity → Alpsnd Pro. A 6-mic ENC system rated to cut up to 97% of background noise is the more call-focused setup on paper.
• Best for noise reduction figures → close call, lean Alpsnd Pro on the stated 50dB ANC ceiling; lean Konnek Stein True if the 90%-of-background-noise framing matches how you think about it. Both are active noise cancelling.
• Best for sound customization → Alpsnd Pro. App EQ control and touch settings versus fixed tuning on the Konnek Stein True.
• Best for a compact sliding case → Konnek Stein True. The slide-open 500mAh case is its signature design feature.
• Best for newer connectivity → Alpsnd Pro. Bluetooth 6.0 and low-latency mode versus Bluetooth 5.1 with a 10-meter range.
• Best for a larger driver → Alpsnd Pro. 13mm dynamic driver versus 10mm on the Konnek Stein True.
In my opinion, the Alpsnd Pro is the safer buy for most people. Twenty hours of playtime, Bluetooth 6.0, app EQ control, a 13mm driver and a 6-mic call system cover more of what a typical buyer actually does — commuting, working, taking calls and streaming — than a slightly stronger noise-reduction claim alone. I would pick the Konnek Stein True instead if the sliding case, the four-times case recharge, or a lower-risk entry into ANC earbuds matters more to you than runtime and app tuning. Either way, check the current price on Amazon before deciding, since that is the one variable that can flip this call.
FAQ
can i wear waterproof headphones in the shower
are headphones waterproof
Rarely in the literal sense. IPX4 means splash- and sweat-resistant, not waterproof. Neither of these two sets is rated for swimming or submerging, so treat them as gym and commute earbuds that can handle moisture, not as something you can dunk or wear in the pool.
which one is better for calls in noisy places
On paper, the Alpsnd Pro. Its 6-microphone ENC system is rated to reduce up to 97% of background noise, which is a call-specific feature the Konnek Stein True does not list. The Konnek Stein True still handles call answering and voice assistant activation via touch controls, so it works fine for quieter calls.
which one lasts longer on a single charge
The Alpsnd Pro. It lists up to 20 hours of playtime, while the Konnek Stein True lists about 5 hours of music playtime per charge. The Konnek Stein True offsets this with a 500mAh case that can recharge the buds roughly four times, so total time with the case is closer than the per-charge gap suggests.
