If you want a wired, audiophile-grade in-ear that leans on a true planar driver for high and ultra-high frequency detail, choose Bawjog KZ PRX Planar; if you need wireless freedom, active noise cancellation and marathon battery life for travel and commuting, choose 1MORE Over Ear.
• Bawjog KZ PRX Planar — biggest strength: a fourth-generation planar magnetic driver with a silver vacuum-plated diaphragm and a 14-magnet N52 array, plus a 20–40000Hz frequency range and a detachable 0.75mm silver-plated cable. That is a lot of hi-res hardware in an in-ear shell.
• Bawjog KZ PRX Planar — biggest trade-off: it is wired only, passive noise cancellation only, and you are locked into a 3.5mm jack. No Bluetooth, no ANC, no carrying case in the box.
• 1MORE Over Ear — biggest strength: LDAC hi-res wireless audio, Bluetooth 5.4, QuietMax ANC that cuts 45dB+ of noise, and up to 100 hours of playback (65 hours with ANC on) with a 5-minute quick charge worth 10 extra hours.
• 1MORE Over Ear — biggest trade-off: it runs a dynamic driver rather than a planar one, it is a bulkier over-ear design at 15.84 ounces, and the enclosure is plastic.
• Pick Bawjog KZ PRX Planar if you listen critically at a desk or on a wired setup and care most about treble extension and driver technology.
• Pick 1MORE Over Ear if you want one pair that handles flights, offices and long listening sessions without a cable.
The KZ PRX is built around a planar magnetic driver, and that is the whole point of the product. Unlike a conventional dynamic driver, a planar driver electroplates a conductive metal layer directly onto the diaphragm instead of winding a thick voice coil around it. That removes weight from the moving assembly, which is exactly why planar designs tend to extend further into the high and ultra-high frequencies. The spec sheet backs this up with a 20–40000Hz range. If you have read about what hi res headphones actually do, this is the kind of engineering that makes it possible.
Buy these if you are an in-ear listener who wants to hear the upper register of a recording clearly, you like the idea of swapping cables, and you are happy to sit within reach of a 3.5mm jack. The ear-wrap fit and ergonomic shell shape are designed for long sessions. Skip them if you need noise cancellation on a plane, if you refuse to deal with wires, or if you want over-ear cushions. Noise control here is passive only, which means the seal does the work. Worth knowing: the model number is PRX, the manufacturer is Dongguan Yuanze Acoustics Technology, and the warranty runs one year.
1MORE Over Ear: Who It's For
The 1MORE Over Ear (model HQ51, sold as the SonoFlow Pro) is the opposite kind of product. It is a wireless over-ear built around convenience and hi-res streaming. LDAC is the headline: it carries roughly three times the data of standard Bluetooth, which is what lets a wireless pair actually deliver the detail that the hi-res label implies. Add Bluetooth 5.4 for a stable modern connection, and a 3.5mm wired mode for when the battery is empty or you are on a plane's seat-back jack.
The 40mm diamond-like drivers cover a 20Hz–40,000Hz range, and the tuning was done by Grammy-winning engineer Luca Bignardi, aimed at a natural, balanced, studio-style presentation rather than a bass-heavy one. Impedance is 32Ω, which is normal for a wireless can and mostly academic since it has its own amplification.
Where this pair really separates itself is travel. QuietMax dual-feed ANC blocks 45dB+ of external noise, which is the difference between hearing your music and hearing the engine. Battery life is rated up to 100 hours standard and 65 hours with ANC on, and a 5-minute charge buys about 10 more hours — genuinely useful when you realize you forgot to charge before a flight. AI-powered noise reduction on the mics keeps your voice clear on calls. At 15.84 ounces with protein leather cushions and an adjustable headband, it is a full-size headphone, so it is comfortable for hours but not something you forget you are wearing. The box includes a carrying case. Buy it if you commute, fly, work in a noisy room, or take a lot of calls. Skip it if your priority is planar driver detail at a desk and you do not care about wireless.
• Best for pure hi-res driver technology → Bawjog KZ PRX Planar. A true planar magnetic driver with a silver-plated diaphragm and N52 magnet array is a different approach than a dynamic driver, and planar designs are known for upper-frequency extension.
• Best for hi-res wireless → 1MORE Over Ear. LDAC plus Bluetooth 5.4 is the combination that lets a wireless headphone carry hi-res-grade audio.
• Best for noise cancellation → 1MORE Over Ear. QuietMax cuts 45dB+ actively; the KZ PRX relies on passive isolation from the ear tip seal.
• Best for battery life → 1MORE Over Ear. Up to 100 hours standard, 65 with ANC, plus a 5-minute quick charge for 10 hours.
• Best for a wired, low-impedance setup → Bawjog KZ PRX Planar. 15Ω and a 3.5mm jack mean easy driving from modest sources, with a detachable 0.75mm cable that can be replaced.
• Best for calls and travel → 1MORE Over Ear. AI noise reduction on the mics and a carrying case make it the better travel companion.
• Best for critical desktop listening → Bawjog KZ PRX Planar. In-ear fit, planar detail and a silver-plated cable suit focused listening sessions.
• Best if you want one pair to do everything → 1MORE Over Ear. Wireless, ANC, wired fallback and long battery cover far more situations.
My Verdict
what is hi res headphones
Hi-res headphones are headphones capable of reproducing frequencies beyond the roughly 20kHz limit of standard audio, usually up to 40kHz. Both of these qualify on paper: the Bawjog KZ PRX Planar reaches 20–40000Hz, and the 1MORE Over Ear reaches 20Hz–40,000Hz.
what is hi res audio headphones
It refers to headphones that can carry a hi-res audio signal without stripping it down. The 1MORE Over Ear supports LDAC, which transmits about three times the data of standard Bluetooth, and carries dual Hi-Res certification; the KZ PRX handles the same range over a wired 3.5mm connection.
which headphones support hi res lossless
For genuinely lossless playback you want a wired connection, which both offer via 3.5mm. The Bawjog KZ PRX Planar is wired only, so it is always lossless-capable; the 1MORE Over Ear is lossless over its wired mode, while its wireless mode uses LDAC, which is high-bitrate but still a Bluetooth codec.
do wireless headphones sound as good as wired ones
Not identically. Bluetooth codecs like LDAC compress the signal, while a wired connection passes it through directly. The KZ PRX's planar driver also gives it an inherent edge in upper-frequency extension, which is why the 1MORE includes a 3.5mm wired mode for when you want the cleanest possible path.
