[Late July 2026] Panasonic RB-C10
The RB-C10 is an accessory-like ear-cuff set that fits your ear at about 5.5g
With open-ear earphones, the longer you wear them, the more weight and pressure matter. Panasonic says the RB-C10's about-5.5g weight and shape-memory alloy bridge fit any ear shape.
A structure that spreads pressure on the ear gives a fit Panasonic calls "Airy Fit", meant to reduce pain and discomfort over long wear. It comes in black, white pearl and sakura pearl.
As an IT consultant (SE), I read the footnote before the headline number. The "late July" release date carries a note that it may be delayed or supply may be late due to the social situation.
How I judged it
First, connection. It supports multipoint pairing with two devices at once, such as a PC and a phone. You can take a call that arrives mid-meeting without re-pairing.
Next, how it handles situations. A "polite" mode reduces sound leakage, so less sound escapes on a train or in an office. For calls it adds ENC to cut environmental noise.
If you can't decide, take the RB-C10. The reason: in the mid-JPY 10,000s you get about 5.5g a side, two-device pairing and leak reduction.

How does it differ from the LinkBuds Clip and FreeClip 2 S?
| Item | RB-C10 | Sony LinkBuds Clip | HUAWEI FreeClip 2 S |
|---|---|---|---|
| Weight per bud | About 5.5g | ― | 5.1g |
| Per charge | 7.0 hours | Up to about 9 hours | About 9 hours |
| With case | 26 hours | Up to about 37 hours | Up to 38 hours |
| Fast charging | 60 minutes from 15 | 1 hour from 3 minutes | 3 hours from 10 minutes |
| Water resistance | Splash-resistant | IPX4 | IP57 |
| Price | Open (Rakuten JPY 14,986) | Open (Rakuten in the JPY 20,000s) | Expected JPY 32,780 |
Battery is 2 hours shorter than the Sony's and HUAWEI's roughly 9 hours (about 22%). Fast charging is slower too, at 4 minutes per minute for the Panasonic.
In return, it is the cheapest of the three and has two-device pairing. For price and easy pairing, take the RB-C10. For battery and charging speed, the LinkBuds Clip.
Strengths and things to note
Strengths
Light and kind to the ear. About 5.5g and a pressure-spreading bridge make it easy to wear for long.
Work-friendly features. Two-device pairing, call noise reduction and physical buttons suit work breaks.
Things to note
7.0 hours per charge is on the short side among ear-cuff models. Fast charging gives about 60 minutes from 15. Your ears stay open, so there is no noise cancelling. Panasonic notes that the release date may slip because of the social situation.
Who is it for?
People who switch between a PC and a phone and want to take calls in online meetings. People looking for a light ear-cuff set in the mid-JPY 10,000s. It also suits anyone worried about sound leaking on trains or in offices.
If you put battery and fast charging first, the Sony LinkBuds Clip is another way to choose.
Price and where to buy
It is an open price, and Panasonic's official Rakuten store and others show JPY 14,986. Over a year, that is about JPY 41 a day (14,986 ÷ 365).
If you can't decide, take the RB-C10. The reason: about 5.5g, two-device pairing and leak reduction together in the mid-JPY 10,000s.
