If you want rechargeable FM radio headphones with long stated battery life, choose kamapulo X5; if you need a wired headset with a microphone for calls, choose LORELEI X6. For everyday calls, the LORELEI’s microphone is the clearest reason to pick it, while the X5 is the more versatile choice for listening to FM radio away from a phone.
• kamapulo X5 strength: Built-in FM radio, a preset-channel shortcut, AUX input, and a stated battery life of up to 24 hours. Trade-off: It has no microphone listed, so it is not the straightforward pick for calls.
• LORELEI X6 strength: Wired 3.5 mm connection and a listed microphone, making it the more call-focused option. Trade-off: It has no built-in radio or rechargeable battery.
• Choose the X5 if you want to listen to FM stations while working outside, walking, or doing other activities without relying on a phone for audio.
• Choose the X6 if your priority is a simple wired headset for phone, tablet, or other compatible-device calls and listening.
The kamapulo X5 is built around a feature the LORELEI does not offer: an FM receiver. It covers the 87.5–108 MHz range, and the product information describes a preset-channel function that lets you return to a favorite station with the M button. That setup makes sense for someone who wants radio on hand during yard work, hiking, jogging, or time away from a phone-based playlist.
It also includes a 3.5 mm AUX input, so you can connect compatible devices with the included cable. The built-in rechargeable battery is stated to run for up to 24 hours, with a charge time of about 2.5 hours. The back-lit display and foldable design are practical details for nighttime use and carrying. At 205 g, it is the lighter of these two models according to their listed weights.

The X5 suits listeners who want radio, rechargeable operation, and the option of wired audio input in one headset. Its soft memory foam and adjustable headband are intended to support longer wear, while the large earcups are described as helping isolate outside sound. Skip it if you specifically need a listed microphone for voice calls: the X5’s provided features do not identify one.
The LORELEI X6 is the more direct fit for someone shopping for a wired headset with a microphone. It connects through a 3.5 mm jack, so it is designed for compatible phones, tablets, and other devices with that connection. The cable-based setup also means it does not depend on the X5’s rechargeable battery.
Its listed driver size is 40 mm, and its frequency range is 20 Hz–20,000 Hz. Those are useful specifications for describing its audio hardware, but they do not establish call clarity or sound quality on their own. The product information lists a microphone, yet does not provide detailed microphone specifications, so shoppers should not assume particular voice pickup or noise-handling performance.
The X6 is foldable and described as lightweight and portable, although its listed weight is 256 g—heavier than the X5’s 205 g. It is a sensible choice for calls and wired listening when your device has a compatible jack. Skip it if you want built-in FM radio, wireless listening, or rechargeable operation; those features are not listed for this model.
• Best for calls → LORELEI X6. It is the only one of the pair with a microphone listed, which makes it the more suitable starting point for calls.
• Best for FM radio → kamapulo X5. Its built-in receiver covers 87.5–108 MHz, and its preset function helps you return to a favorite station.
• Best for avoiding battery charging → LORELEI X6. Its connection is wired, so it does not rely on the X5’s rechargeable battery.
• Best for long listening away from a charger → kamapulo X5. Its stated battery life is up to 24 hours, with a listed charging time of about 2.5 hours.
• Best for a wired music-and-call setup → LORELEI X6. It combines a 3.5 mm connection with a listed microphone; check that your device has a compatible jack.
• Best for radio plus AUX audio → kamapulo X5. It can receive FM and also accept audio through its 3.5 mm AUX input.
• Lighter listed weight → kamapulo X5. The X5 is listed at 205 g, compared with 256 g for the X6.
• Best for a phone-free listening option → kamapulo X5. Its FM receiver lets you tune into broadcasts without using a phone as the audio source.
The phrase “gaming headset for calls” may sound like a fit for either model, but neither sheet identifies gaming-specific features. For voice chat, the X6’s microphone is the more relevant listed feature; the X5 is better understood as a radio headset with an AUX option, not as a dedicated call headset.
I would choose the LORELEI X6 for calls because it is the only model here with a microphone listed and connects through a standard 3.5 mm jack. That makes it the more convincing choice if calls are the main job, including for someone searching for the best headset for calls from these two options. I’d choose the kamapulo X5 instead if FM radio, rechargeable listening, and a stated battery life of up to 24 hours matter more than taking calls.
The LORELEI X6 is the clearer choice based on the listed features because it includes a microphone. The X5 has FM radio and AUX input, but no microphone is identified in its product details.
The X5’s adjustable headband and soft memory foam are described as comfort features, but the listed details do not identify a microphone or sleep-specific design. For calls, the X6 is the more suitable option of these two because a microphone is listed.
The X5 has a built-in rechargeable battery with a stated runtime of up to 24 hours and a charge time of about 2.5 hours. The X6 is wired, and no rechargeable battery life is listed for it.
Choose the kamapulo X5. It combines an FM receiver with a 3.5 mm AUX input, whereas the X6 is described as a wired headset without a built-in radio.
