The universe of audio equipment is not unfamiliar with nostalgia, but now and then there’s a product that doesn’t just tip its hat to the past—it brings it into the present in an intelligent, meaningful manner. The km5 Lightwear Hp1 headphones do just that, capturing the unmistakable character of 1980s Walkman headsets and combining it with wireless technology and features you’d want in 2025.
Design Philosophy: Where Retro Meets Minimalism
km5, the company responsible for the stunning, see-through CP1 CD player, has a true talent for updating retro looks. The HP1 takes the on-ear, slim design of vintage portable headphones and gives it a crisp, contemporary spin. The stainless steel headband is smooth to the touch but still keeps things light, weighing only 103 grams. The result is a pair of headphones that are as great-looking as they are great-feeling, and comfortable enough to wear all day.
Customization is also a major factor here. The ear cushions are soft, magnetic, and simple to replace. Every pair includes two pairs in different colors, so you can mix up your look whenever you like. Whether you opt for the black or white version, there’s a subtle but apparent dose of personality in the design that makes the HP1 distinguishable.
Technical Features: Innovative Tech in a Timeless Package
Don’t let the retro feel fool you—the HP1 is packed with tech. Within every earcup lies a 40mm driver, a size more commonly seen in larger over-ears. What comes out is a deceptively full and strong sound. Bluetooth 5.4 is present, with SBC, AAC, and LE Audio codecs supported, which translates to a good wireless connection and exceptional audio quality.
The one thing that impresses is the active noise cancellation. It’s not something that you usually find in light-on-ear headphones, but km5 has managed to make it happen. The ANC works well to reduce background noise, and this makes it a great choice for commutes or busy areas. There’s also a transparency mode available so that you can listen to what’s happening around you when you need to—great for being aware in a congested city.
User Experience: Lightweight, Comfortable, and Intuitive
Coming in at barely more than 100 grams, the HP1 is extremely light. The stainless steel headband puts just the right amount of pressure on to remain secure, without ever feeling too tight or uncomfortable. The ear cushions provide a further layer of comfort and are easy to replace when they wear down or whenever you want to mix up the look.
Rather than touch-sensitive controls, the HP1 employs physical buttons to play music, adjust volume, and activate the voice assistant. It’s a good, uncomplicated approach that is easy and accessible, providing a tactile touch that, in a world of touch-everything, is refreshing in its simplicity.
Performance: Sound, Battery, and Connectivity
The quality of the sound is where the HP1 truly shines. With those 40mm drivers, the music sounds balanced and full, with a level of clarity and depth that will provide anything from pop song playlists to vintage records. For a higher level of quality, the wired USB-C option can play back up to 24-bit/96kHz.
Battery life is also one of its major selling points. You can listen for up to 24 hours on a single charge, and full charges for both earcups take three hours. One quirky detail to keep in mind: each earcup contains its battery, so you’ll be charging them separately. It’s a little unorthodox, but a reasonable trade-off for the light design.
Market Position: A Niche for the Style-Conscious Listener
Priced at about $189 (approximately JPY 22,000), the km5 Hp1 puts itself right between affordable wireless headphones and high-end audiophile equipment. It’s just perfect for someone who desires excellent sound and exceptional design, particularly if you have a fondness for vintage technology. The customization features, clean look, and focus on comfort set these headphones apart.
In a world of shiny, futuristic-looking headphones that all seem alike, the HP1 stands out. It proudly celebrates its vintage heritage but provides the features that are most important to today’s listeners. If you’re a person who cares about style as much as sound, and you’re looking for a pair of headphones that is personal, functional, and a bit retro, the km5 Lightwear HP1 is well worth a place in your gear arsenal.
