Philips Fidelio L4 Review | 93 Data compared

The Philips Fidelio L4 is a premium, over-ear Bluetooth headphone praised for its exceptional, clear, and natural sound quality that outperforms competitors like the Bose QuietComfort Ultra and Sony WH-1000XM5 in clarity and detail reproduction. Weighing 320 grams, it features a high-quality build made of leather and painted aluminium brackets, housing large 4 cm graphene-coated drivers that deliver deep, clean bass. Key pros include its comfortable fit with well-distributed pressure, a highly versatile companion app for sound and active noise cancellation (ANC) adjustments, and reliable physical controls via button and touch-surface combinations. It supports high-quality AAC and LDAC audio codecs and provides a strong battery life lasting over two days on a single charge with ANC activated. On the downside, the review highlights a few notable cons, such as the complete lack of APT-X codec support and the requirement to enable LDAC manually through both the app and Android developer options for optimal performance. Additionally, its active noise cancellation is less powerful and drapes less environment noise than the "radical" isolation offered by Apple or Bose models. At 320 grams,...

The Philips Fidelio L4 is a high-end, over-ear Bluetooth headphone that represents a complete redesign rather than a minor update to its predecessor, the L3. It features a new rounded headband and refined 40mm drivers that deliver an exceptionally balanced, high-resolution sound with deep bass and detailed highs. The build quality is excellent, using premium materials that offer a lighter weight and improved comfort for long listening sessions. It supports modern codecs like LDAC and LC3 via Bluetooth 5.3, providing up to 50 hours of battery life without noise canceling, and 40 hours with it active. Pros and Cons Pros: The headphones excel in audio fidelity, offering a "Spitzenklasse" (top-tier) sound performance with great spatiality and detail. The adaptive noise canceling is highly effective at filtering out travel noise, and the companion app offers extensive customization for transparency modes and EQ settings. Additionally, the battery life and build quality are significant highlights. Cons: A notable drawback is the loss of aptX support, which was available in the previous model. Furthermore, activating Noise Cancelling or specific transparency modes can audibly alter...

Retailing at a recommended price of €349.99, it boasts high-quality build materials like metal for the headband and ear cup brackets, alongside premium synthetic leather on the padding. The headphones feature newly developed 40mm graphene-coated drivers and support cutting-edge connectivity including Bluetooth 5.3, Bluetooth Multipoint, Google Fast Pair, and Auracast technology. In terms of functionality, they use an intuitive combination of physical buttons on the left ear cup for ANC controls and a seamless touch panel on the right ear cup for media playback. The package also includes a durable, water-resistant hardshell case, a 20cm USB-A to USB-C charging cable, and a 120cm audio cable for wired listening. Several major pros and cons stand out from the testing process. On the positive side, the Fidelio L4 delivers outstanding comfort and highly satisfying haptic feedback, featuring precise physical buttons and a smooth, non-stepped headband adjustment mechanism that remains securely in place. Its battery life is highly impressive,...

The Philips Fidelio L4 is an over-ear Bluetooth headphone that positions itself as a versatile, well-rounded performer in a slightly elevated price range, just below the true high-end tier. In terms of audio performance, it delivers a balanced, natural, and well-rounded soundstage that avoids exaggerated frequencies, making it an appealing option for listeners who prefer an uncolored audio profile. On the functional side, it excels with an impressive battery life of up to 50 hours with active noise cancelling (ANC) turned off, seamless Bluetooth multipoint connectivity, and helpful touch controls on the ear cups. Additionally, it features useful auto-pause capabilities when removed, a robust companion app equipped with an equalizer, and clear internal left-right indicators. However, the headphones fall short when it comes to ambient noise management. The primary drawback is its weak passive noise isolation, which directly limits the effectiveness of its ANC system, leaving it unable to compete with top-tier models from Bose or Sony. Its transparency mode also feels somewhat unnatural, and the sound profile can occasionally feel a bit thin or lacking in deep, punchy bass...

The Philips Fidelio L4 is a premium Bluetooth over-ear headphone that balances a luxurious aesthetic with highly precise, natural sound quality. Built with high-end materials like aluminum and soft Muirhead leather, it features 40mm graphene-coated drivers that deliver a wide soundstage, crisp highs, and deep, distortion-free bass. Its active noise-cancelling (ANC) efficiently eliminates low-frequency ambient sounds, while high-frequency voices are filtered intelligently, and can be customized alongside EQ settings via the Philips companion app. Additionally, it boasts an impressive battery life of up to 50 hours (40 hours with ANC enabled) and supports flexible wired connections and advanced Bluetooth codecs like LDAC for Android and AAC for iOS. On the positive side, the headphone stands out for its excellent overall audio performance, exceptional build quality, long-lasting battery life, and high wearing comfort thanks to its balanced weight distribution. It also provides outstanding call quality through beamforming microphones and AI algorithms that filter background noise. However, it does carry a few notable disadvantages, including being heavier than several of its direct market competitors and lacking support for any variant of the...

The audiovision review of the €350 Philips Fidelio L4 wireless over-ear noise-cancelling headphones concludes with an overall rating of "Very Good" (Sehr gut). The reviewer notes that while the initial unboxing experience was marred by an unpleasant chemical smell from the test unit, it dissipated after a few days. Once operational, the headphones excel in audio performance, delivering a dynamic, gripping, and high-resolution three-dimensional soundstage across all frequencies when listening to tracks from artists like Tears for Fears and The Eagles. Usability is smooth thanks to standard touch gestures and physical buttons directly on the earcups, alongside a comprehensive accessory package that includes a sturdy carrying case, a USB charging cable, and a 3.5 mm audio jack cable.

The Philips Fidelio L4 is a premium Bluetooth over-ear headphone that strikes an excellent balance between high-end design and an adult, balanced sound signature. Weighing 320 grams (40 grams lighter than its predecessor), it features slightly oval-shaped ear cushions covered in premium Muirhead leather and a slimmed-down aluminum frame suspension that distributes weight effectively for long-term wearing comfort. Equipped with 40mm graphene-coated dynamic drivers, the headphones deliver a remarkably wide and airy soundstage with excellent separation of mids and highs, deviating from market trends by offering a clean, controlled bass response rather than an overemphasized punch. It includes comprehensive modern features such as reliable touch-gesture controls, multi-point connectivity for two devices, an optimized low-latency mode suitable for gaming, and forward-looking Auracast support.

The Philips Fidelio L4 is an over-ear wireless headphone featuring an updated, slimmer headband design and a premium aluminum frame that ensures excellent comfort and structural stability without pressing on the user's head. It delivers an impressive 40 hours of battery life with exceptional quick-charging capabilities (14 hours of playback from a 15-minute charge) and offers outstanding connectivity. It functions as a passive headphone via a 2.5mm to 3.5mm jack without draining the battery, and it can even operate as an external DAC when connected directly to a PC or smartphone via USB-C. Sonically, the L4 excels with a highly detailed and balanced frequency response, featuring punchy, controlled bass, remarkably clear mids for excellent speech intelligibility, and smooth, refined highs. However, the headphones suffer from a notably low volume level when used in active Bluetooth mode or as a DAC, requiring users to turn up the volume by roughly 25% compared to competitors. While its Active Noise Cancelling (ANC) handles ambient noises like trains or vacuums effectively, it cannot quite match the industry-leading isolation of the Sony WH-1000XM5. Additionally, the...
