Panasonic RZ-S500W

The Panasonic RZ-S500W true wireless earbuds deliver excellent noise cancelling and best-in-class mic quality at a mid-range price. Fit is inconsistent and the touch controls are finicky, but if calls and ANC matter most, these are a strong value, especially near USD 118.

Let's talk numbers. The mic quality on the RZ-S500W lands in the 98th percentile of all earbuds we track. That's not just good, that's best-in-class territory. Six MEMS mics with beamforming and a labyrinth structure to cut wind noise means your voice comes through clean even when you're walking down a windy street. If you take a lot of calls, this is a standout feature.

ANC performance is also a bright spot, sitting in the 93rd percentile. The dual hybrid setup with feedforward and feedback mics plus analog and digital processing does real work. It won't completely erase a crying baby on a flight, but it takes the edge off engine drone and office chatter better than most buds at this price. Sound quality is more middle of the pack at the 70th percentile. The 8mm driver delivers rich bass and decent detail, but it's not going to blow away anyone who's heard the Sony WF-1000XM6 or Technics EAH-AZ100. Battery life is solid if unspectacular at 6.5 hours per charge with about 19.5 more in the case, and the quick charge gives you 70 minutes from 15 minutes of charging. Connectivity is strong at the 81st percentile, with stable left-right independent signaling that resists dropouts in crowded areas.

Stacked against the Sony WF-1000XM6, the Panasonic RZ-S500W actually holds its own on mic quality and ANC, but Sony wins on sound refinement, app polish, and overall fit consistency. The Sony buds are more expensive, but they feel like a complete product. The Technics EAH-AZ100 is an interesting comparison since Technics is Panasonic's own premium audio brand. The EAH-AZ100 delivers better sound and a more premium build, but you'll pay for it. If you want the Panasonic family sound without the compromises, that's the upgrade path.

Against the Apple AirPods Pro 3, the RZ-S500W can't match the seamless iOS integration or the transparency mode polish, but Android users won't care about that. The Soundcore P31i and EarFun Air Pro 4+ are the budget alternatives. They cost less and offer decent ANC, but neither touches the RZ-S500W's mic quality or noise cancelling depth. If calls matter more than music, Panasonic has a real edge here.

Value is tricky here because the price swings a lot. You'll see these listed anywhere from USD 118 to USD 180 across US retailers, and that USD 62 spread changes the math completely. At the low end, the RZ-S500W is a steal for the ANC and mic quality alone. At the high end, you're dangerously close to Sony WF-1000XM6 or Apple AirPods Pro 3 territory, and those are better overall packages. If you can find these closer to USD 118, they're worth a serious look. If you're staring at USD 180, save your money or wait for a sale. The CAD 244 and MXN 3,424 listings don't help much either, those are just the going rates in those markets.

The Panasonic RZ-S500W sits in that crowded true wireless earbuds space where everyone promises great noise cancelling and solid sound, but few actually deliver at a price that doesn't make you wince. These are Panasonic's shot at the premium ANC market, and on paper they bring some serious hardware: dual hybrid noise cancelling, six microphones, an 8mm dynamic driver, and IPX4 water resistance. You'll find them floating around USD 118 to USD 180 depending on the listing, which puts them in that awkward middle ground between budget picks and flagship Sony or Apple buds.

So is the Panasonic RZ-S500W good for travel, calls, or just drowning out your coworkers? The short answer is that the noise cancelling is genuinely impressive, the mic quality is top-tier, and the fit is a gamble. If your ears cooperate, these are a hidden gem. If they don't, you'll spend half your day fishing them out from under your desk.

We dug through our database and a pile of owner feedback to figure out where these shine and where they stumble. The headline: excellent ANC and call quality, but some baffling design choices keep them from being an easy recommendation for everyone.

Skip the RZ-S500W if you're buying earbuds primarily for music and care about getting the best sound quality for your dollar. The 70th percentile sound ranking means you can do better elsewhere, especially if you're paying near the USD 180 end of the price range. Also skip these if you have smaller or unusually shaped ear canals, the fit complaints are too consistent to ignore. Runners and gym-goers should look elsewhere too, these aren't built for movement. If you want better sound and a more secure fit, check out the Sony WF-1000XM6 or the Technics EAH-AZ100. If you're on a tighter budget and just want decent ANC, the Soundcore P31i or EarFun Air Pro 4+ will save you money without the fit gamble.

Should you buy the Panasonic RZ-S500W? If you take a ton of phone calls and want genuinely strong noise cancelling without paying Sony or Apple prices, yes, especially if you can snag them near the USD 118 mark. The mic quality alone makes these worth considering for remote workers and frequent callers. The ANC is legitimately good, and the battery life won't leave you stranded.

But if you're buying these primarily for music, or if you have ears that don't play nice with generic earbud shapes, think twice. The fit complaints are real and frequent. Owners report the buds falling out during movement, and the overly sensitive touch controls add frustration. The flashing blue LED is the kind of small design flaw that makes you wonder if anyone at Panasonic actually wore these for a full day. These are great earbuds with a few annoying asterisks.
