Key Takeaways
1. Lightweight Design: The km5 Hp1 headphones weigh only 3.6 ounces, featuring a minimalist headband without padding for comfort and reduced weight.
2. Nostalgic and Modern Blend: Inspired by ’80s and ’90s models, the headphones incorporate modern technology like Bluetooth 5.4 and LE Audio for enhanced connectivity.
3. Long Battery Life: The Hp1 offers up to 24 hours of playtime on a single charge, with a full recharge taking approximately three hours via USB-C.
4. High-Quality Sound: Equipped with dynamic 40mm drivers, the headphones deliver audio at 24-bit and 96 kHz, with a frequency range of 20Hz to 25kHz and low distortion.
5. Independent Powering: Each earcup has its own battery and must be powered on/off separately, with dedicated buttons for playback and volume control on both sides.
At first sight, the km5 Hp1 headphones bring to mind the vintage models that were once paired with Sony Walkmans and Discmans from years past. While the headband lacks padding and might seem a bit uncomfortable, this design feature helps keep the weight down to a mere 3.6 ounces, which supposedly makes any cushioning unnecessary. In contrast, the ear pads are crafted from soft fabric and are attached magnetically, allowing for easy replacement.
Nostalgic Meets Modern
These headphones strive to blend the vibes of the ’80s and ’90s with current technology since the Hp1 supports Bluetooth 5.4, including Bluetooth LE Audio. Km5 claims the headphones can last for 24 hours on a single charge, and a full recharge via USB-C takes approximately three hours. When connected to a smartphone or computer through USB-C, they can stream music at a stunning 24-bit and 96 kHz, which should give a frequency range of 20Hz to 25kHz.
Advanced Sound Features
The Hp1 comes equipped with dynamic 40mm drivers, boasting a sensitivity of 122 dB/mW and a minimal total harmonic distortion of 0.2%. On both earcups, there are dedicated buttons that allow users to manage playback and change volume levels. Uncommonly for Bluetooth headphones, users must power each side on and off separately as there’s no connecting cable. Each side is fitted with its own 120mAh battery that requires independent charging.
Currently, the km5 Hp1 Bluetooth headphones can be purchased directly from the manufacturer’s website. The price is set at $189, not including shipping costs. The manufacturer also notes that additional import fees might be applicable.
