## Panasonic ErgoFit RP-HJE120

Our rating: 7.5 out of 10.

Best for: A spare pair for a gym bag, a desk drawer or a suitcase, where losing them costs nothing.

The ErgoFit is here because the honest answer to "what should I keep in my bag" has not changed in years. It is a single 9mm dynamic driver in a light plastic shell with an angled, oval nozzle that sits along the ear canal rather than pointing straight in, which is why it seals for people who struggle with round nozzles.

The tuning is warm and rolled off at the top. That is not accuracy, but it means podcasts and older recordings are easy to listen to and nothing ever gets sharp, which is the right choice at this end of the market. Three tip sizes are included and the cable is thin and light enough not to tug the earphone out when it catches on a jacket zip.

The limits are exactly what you would expect. The cable is fixed, so when it frays at the Y-split (and it will, usually within two years of daily use) the earphone is finished. Cable noise transmits up the wire when you walk, the plastic housing feels disposable, and there is no detail retrieval to speak of once you have heard anything better. Buy it as the pair you do not mind losing.

## Truthear x Crinacle Zero:RED

Our rating: 8.8 out of 10.

Best for: One wired set for everything, chosen for tonal correctness rather than excitement.

The Zero:RED is the set to buy, and the reason is the tuning process rather than the parts list. Crinacle publishes measurements for a living, and this is tuned toward a documented target instead of toward whatever sells on a demo table, so the response is even where it matters and the deviations are deliberate.

The hardware is a 10mm plus 7.8mm dual dynamic arrangement with LCP diaphragms, behind a 0.78mm 2-pin detachable cable. In practice that means vocals sit forward and clear, the treble carries detail without the peak that makes the ZS10 Pro sting, and there is a sub-bass shelf that adds weight underneath rather than bloating the midbass. It is easy to drive and does not need an amp.

The fit is the real caveat. The nozzle is wider than average, so third-party tips are a fight to seat and smaller ear canals find it uncomfortable after an hour. The shells are unremarkable plastic. And if you are coming from a V-shaped hybrid the bass will read as restrained for the first week, because it is: this is a set that gets the tone right rather than one that impresses immediately.
