kamapulo X5 vs Philips Fidelio X3 at a Glance
• kamapulo X5 strength: Built-in FM radio, AUX input, and up to 24 hours of battery life. Trade-off: It tunes FM only and does not offer the X3’s open-back listening design.
• Philips Fidelio X3 strength: Open-back construction and 50 mm multi-layer diaphragms, designed for spacious, detailed sound. Trade-off: It is wired and lets surrounding sound in.
• Choose the X5 if portability, radio listening, and a rechargeable battery matter most.
• Choose the X3 if you mainly listen in a quiet space and want wired, open-back headphones.
The X5 is a practical, feature-led headset. Its built-in receiver covers FM from 87.5 to 108 MHz, so you can listen to FM programs without connecting a phone or another audio source. There is no AM reception. For other devices, the included 3.5 mm AUX cable provides a wired option.
Its rechargeable battery is listed for up to 24 hours of operation and takes about 2.5 hours to charge. A preset button offers quick access to a favorite channel, and the backlit LED display is useful when checking controls in dim conditions. The headset weighs 205 g and folds for easier carrying. Soft memory foam ear cushions and an adjustable headband are intended to support longer wear.

I’d consider the X5 for someone who wants a self-contained radio headset for travel or outdoor activities, and who values not having to keep a phone playing audio. The FM receiver and battery make it the more practical of these two for flights, especially if listening to radio is part of the plan. But it is not a direct replacement for a conventional Bluetooth headset: the listed wireless function is FM, while phone playback is through AUX. If your priority is detailed music listening in a quiet room, the Fidelio X3 is the more relevant design.
The Fidelio X3 is a wired, over-ear headphone built around an open-back acoustic design. Philips describes its sound as spacious and uncolored, with 50 mm multi-layer diaphragms intended to deliver detailed highs, smooth midrange, and controlled bass. Its stated frequency response is 5 Hz to 40 kHz. Those specifications and the open construction point toward attentive listening in a quiet environment rather than blocking out a busy one.
The X3 includes balanced and unbalanced inputs, with detachable 3 m cables for those connections. That gives it flexibility with compatible headphone equipment as well as everyday devices with a suitable connection. Its listed impedance is about 32 ohms. The headband is covered in Muirhead leather, and Kvadrat fabric is used in the open-back speaker area.
I’d choose the X3 for home listening, music work, or anyone who prefers an open presentation and does not need isolation. Its main drawback for travel is inherent to its design: open-back headphones allow outside sound in and can also let your audio escape. It has no listed battery-powered listening mode, and the supplied cables are much less convenient on a flight than a portable, foldable radio headset.
• Best for built-in FM listening → kamapulo X5. It has an FM receiver covering 87.5–108 MHz; the Fidelio X3 does not list a radio.
• Best for flights → kamapulo X5, with a caveat. Its foldable design, rechargeable battery, and radio are travel-friendly. Neither sheet lists active noise cancellation, and the X5’s sound isolation should not be mistaken for electronic noise cancellation.
• Best for open, spacious listening → Philips Fidelio X3. Its open-back construction is designed to create a more expansive presentation, but it will not seal out cabin noise.
• Best for use without a phone playing audio → kamapulo X5. The built-in FM receiver can provide audio on its own; the X3 needs a wired audio source.
• Best for a wired home setup → Philips Fidelio X3. It includes detachable balanced and unbalanced cables, with a 3.5 mm connection listed.
• Best for battery endurance → kamapulo X5. Its battery is specified for up to 24 hours, with a listed charging time of about 2.5 hours.
• Best for someone seeking open ear earbuds for flights → neither is an earbud. The X5 is an on-ear radio headset and the X3 is an over-ear open-back headphone. If you mean a lightweight, open-ear fit, these are not that style.
• Best hi res headset for flights → Philips Fidelio X3 only if sound detail matters more than isolation. Its stated response reaches 40 kHz, but the open-back design makes it less suited to a noisy cabin than its listening profile might suggest.
For flights, I’d choose the kamapulo X5. Its FM receiver, foldable build, AUX input, and listed 24-hour battery life make it the more practical travel companion of the two. That is a recommendation for convenience and radio access, not a claim that it cancels cabin noise.
I’d buy the Philips Fidelio X3 for quiet, focused listening at home, where its open-back design and wired connections make more sense. For the travel use case, though, the X5 is the clearer fit.
Is the kamapulo X5 Bluetooth?
The listed wireless function is FM radio, not Bluetooth audio. For playback from a phone, PC, or MP3 player, the X5 has a 3.5 mm AUX input and includes a cable.
Is the Philips Fidelio X3 good for flights?
It can be connected to a compatible audio source, but its open-back design allows outside sound in and may let audio escape. It is better suited to quiet listening than to a noisy cabin.
The product information emphasizes the X3’s open-back design and 50 mm multi-layer diaphragms for detailed, spacious listening. The X5 is more focused on FM reception, portability, and battery-powered convenience, so the right choice depends on your listening priorities.
Check the current price on Amazon before deciding; I can’t determine value without that information. Compare it with your needs: the X5 combines FM, AUX, and a rechargeable battery, while the X3 is a wired open-back headphone with balanced and unbalanced cable options.
