How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a light, everyday pair of in-ear noise cancelling earbuds that disappear in your pocket and put voice controls at your fingertips for calls, choose Panasonic ErgoFit True; if you need maximum battery life, deeper hybrid noise cancelling and a locked-in over-ear hook fit for running and long workdays, choose GOLREX Active Noise Cancelling. Both are true wireless in-ear ANC models, but they solve very different problems — and if calls are your priority, the answer usually comes down to fit, controls and how long you can stay on the line.
• Panasonic ErgoFit True — biggest strength: a genuinely lightweight in-ear design (each bud weighs roughly 4.8 g) with XBS extra bass from 10 mm dynamic drivers, touch plus voice control, and Google Assistant/Siri compatibility.
• Panasonic ErgoFit True — biggest trade-off: battery is modest. Expect up to 5 hours per charge with ANC on (16 hours with the case), and up to 6 hours / 26 hours total with ANC off. Quick Charge gives about 60 minutes of playback from a 15-minute top-up.
• GOLREX Active Noise Cancelling — biggest strength: an 80-hour total playback figure from a 600 mAh charging case with a dual LED battery display, adaptive hybrid ANC that reduces ambient sound by up to 50 dB, and 13 mm drivers for a wider, more detailed sound.
• GOLREX Active Noise Cancelling — biggest trade-off: it's the bulkier proposition. The over-ear hooks and 3.53 oz package are built for sport and stability, not for slipping unnoticed into a jeans coin pocket.
• Who each pick is for: Panasonic for commuters, students and casual listeners who want a compact, bass-forward ANC bud with voice control for calls. GOLREX for runners, gym-goers and heavy users who want long battery, stronger noise reduction and physical buttons.
The ErgoFit True (model RZ-B310W) is the "keep it simple, keep it small" option. It's an in-ear design in a plastic shell, and Panasonic leans hard on the ErgoFit name — three earpiece sizes (S, M, L) so you can dial in the seal that actually holds. That seal matters more than people think: it's what makes both the bass and the noise cancelling feel like they're working. The buds themselves are light at around 4.81 g each, which is the kind of spec that translates into "I forgot I was wearing these" during a long afternoon.
Audio is where Panasonic plays its heritage card. A 10 mm dynamic driver paired with XBS (extra bass system) is tuned for punch rather than neutrality. If your playlist leans hip-hop, electronic or pop, that low-end energy is the point. The noise cancelling is a feedforward/feedback setup with mics inside and outside the housing, aimed at reducing plane, train and bus rumble — exactly the scenarios Panasonic names. There's also a transparency-free approach here: no dedicated ambient mode is listed, so you're either cancelling or not.
Buy it if you want a compact, bass-forward in-ear ANC bud with voice control, a secure multi-size fit and a light feel — and you're fine charging the case regularly. Skip it if you need marathon battery, an ambient/transparency mode, or the kind of grip that survives a sweaty trail run.
GOLREX Active Noise Cancelling: Who It's For
The GOLREX T59 is the endurance athlete of this pair. Everything about the spec sheet points at people who are hard on their gear and hate charging. The charging case holds a 600 mAh battery and GOLREX quotes up to 80 hours of total playback — enough to get through a full workweek of commutes, workouts and meetings without hunting for a cable. A 10-minute quick charge restores about 2 hours. The dual LED display shows the battery status of both the earbuds and the case, which sounds like a small thing until you've been burned by a dead bud five minutes before a call.
Noise cancelling is the headline. GOLREX describes an adaptive hybrid ANC system with a high-speed processor and a 4-layer noise reduction architecture, reacting to changing noise in as little as 0.02 seconds and cutting ambient sound by up to 50 dB. That's a more aggressive claim than the Panasonic's travel-focused ANC, and it's paired with a Transparency Mode so you can hear a conversation or traffic without pulling the buds out. For anyone who works in a busy office or flies often, that combination — strong cancellation plus a quick ambient pass-through — is the practical difference between "noisy" and "usable."
Buy it if you want long battery, strong hybrid ANC with a transparency mode, bigger drivers and a fit that won't budge during sport — and you don't mind a bulkier, hook-style design. Skip it if you want the smallest possible carry, touch controls, or a look that doesn't read as athletic.
Side-by-Side: Which Should You Choose?
• Best for battery life → GOLREX Active Noise Cancelling. Up to 80 hours total from the case versus up to 16 hours (ANC on) from the Panasonic case.
• Best for the lightest, most pocketable carry → Panasonic ErgoFit True. Roughly 4.8 g per bud, no ear hooks, simple in-ear shape.
• Best for strong noise reduction → GOLREX Active Noise Cancelling. Adaptive hybrid ANC quoted at up to 50 dB reduction, plus a Transparency Mode.
• Best for bass-forward everyday listening → Panasonic ErgoFit True. 10 mm drivers with XBS extra bass tuning; the GOLREX counters with larger 13 mm drivers and a more detail-focused tuning.
• Best for workouts and running → GOLREX Active Noise Cancelling. Over-ear hooks, three tip sizes and physical buttons that don't misfire mid-sprint.
• Best for hands-free calling convenience → Panasonic ErgoFit True. Touch controls plus Google Assistant and Siri support, in a lighter package that's easier to wear for long stretches.
• Best for keeping tabs on charge → GOLREX Active Noise Cancelling. The dual LED display on the case shows both bud and case battery at a glance.
• Best for charging flexibility → GOLREX Active Noise Cancelling. Wireless charging plus Type-C, versus USB charging on the Panasonic.
If I had to pick one, I'd buy the GOLREX Active Noise Cancelling for most people who ask me about in-ear noise cancelling earbuds. In my opinion the 80-hour battery, stronger hybrid ANC with a transparency mode, larger drivers and the secure hook fit simply cover more ground — commuting, the gym, long workdays. The one place I'd steer you the other way is calls-first, light-carry use: the Panasonic ErgoFit True is the better companion if you want a featherweight bud with voice control and don't need marathon battery. Whichever way you lean, check the current price on Amazon before you commit, since that's the variable that usually breaks the tie.
There's no single answer — it depends on what you value. The Panasonic ErgoFit True is a strong pick for a light, bass-forward in-ear ANC bud with touch and voice controls, while the GOLREX Active Noise Cancelling suits anyone who wants up to 80 hours of total playback, adaptive hybrid ANC up to 50 dB and a transparency mode.
If "over the ear" means ear-hook sport earbuds, the GOLREX T59 fits the description with flexible over-ear hooks, S/M/L tips and physical buttons. The Panasonic ErgoFit True is a straight in-ear design with no hooks, so it's the lighter, less grippy option of the two.
For quick, hands-free calls the Panasonic has the edge in my view, thanks to touch controls and built-in Google Assistant and Siri support in a very light bud. The GOLREX also has a mic in each earbud and mono mode, so it's perfectly usable for calls — it just comes in a bulkier hook-style package.
The GOLREX wins on total playback, with up to 80 hours from its 600 mAh charging case. The Panasonic quotes up to 5 hours per charge with ANC on and up to 16 hours with the case; with ANC off that rises to about 6 hours and 26 hours total.
