If you want closed-back on-ear headphones with a bass boost button and a folding design, choose Philips TAH4205; if you need longer battery life, two-device pairing, and a built-in microphone, choose Sony WH-CH520. For audiophiles choosing between these two, Sony offers more ways to shape and manage everyday listening, while Philips keeps its appeal focused on bass control and a simple, portable design.
Philips TAH4205 vs Sony WH-CH520 at a Glance
• Sony WH-CH520: Up to 50 hours of battery life, EQ customization, a built-in microphone, and multipoint connection make it versatile. It does not have a headphone jack, and its listed features do not include a dedicated bass boost button.
• Choose Philips if you want a folding on-ear pair with a direct bass control and a design intended to help isolate outside sound.
• Choose Sony if you move between a phone and computer, take hands-free calls, or want more time between charges.
Philips gives you a straightforward set of listening features: Bluetooth 5.0, 32 mm dynamic neodymium drivers, and a bass boost button. That button makes the bass option easy to reach without relying on an app or a preset menu. The closed-back design is intended to help isolate you from unwanted exterior noise, which may suit home listening, a commute, or a travel playlist when you want more separation from your surroundings.
The on-ear format keeps the headphones compact in concept, and the headband folds flat for easier packing. Philips lists a cushioned headband, a weight of 150 g, and a 3.5 mm jack alongside wireless connectivity. Its stated maximum battery life is 29 hours, with a 15-minute fast charge providing up to four hours of use. Those details make it a practical option for someone who wants familiar, simple controls and enough battery for multiple listening sessions before recharging.
I’d consider Philips for a listener who prefers a physical bass adjustment and wants a closed-back design rather than an app-led sound setup. It may also appeal to someone who values the listed wired connection as an alternative to Bluetooth. Skip it if you need the longer stated battery life, multipoint pairing, or an explicitly listed built-in microphone for calls.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.

Sony’s strongest practical advantage is endurance: its stated battery life is up to 50 hours. Quick charging is also specified, with three minutes of charging providing up to 90 minutes of playback. That can be useful when you realize the headphones need power shortly before a commute or a listening session. Bluetooth 5.2 and multipoint connection add flexibility, since the headphones can pair with two devices at once and switch between them.
For sound preferences, Sony offers EQ customization through its Headphones Connect app, including options to adjust the sound to personal taste. DSEE is also listed as a feature intended to improve the presentation of compressed music files. These are useful tools for someone who listens to varied genres or streams from different sources and wants more control than a single bass button provides. Sony also includes a built-in microphone for hands-free calls and supports activating a preferred voice assistant.
The WH-CH520 has an on-ear design, swivel earcups, an adjustable headband, and soft ear pads. Those features point toward easy everyday wear and more compact carrying, though comfort remains personal. Skip it if a 3.5 mm headphone jack is essential: Sony lists no headphone jack for this model.
• Best for a quick bass adjustment → Philips TAH4205. It has a dedicated bass boost button, while Sony’s listed sound adjustments are handled through its app-based EQ.
• Best for switching between a phone and a computer → Sony WH-CH520. Multipoint connection supports pairing with two devices at once, a handy arrangement for music on a laptop and calls on a phone.
• Best for hands-free calls and voice assistant access → Sony WH-CH520. It has a built-in microphone and voice-assistant support. Philips’ supplied details do not list those features.
• Best if you want a 3.5 mm jack → Philips TAH4205. Sony has no headphone jack listed; Philips does.
• Best for a fold-flat headband → Philips TAH4205. Its headband is specified as flat-folding, while Sony’s listed portability detail is its swivel-earcup design.
• Best for app-based sound customization → Sony WH-CH520. EQ Custom gives you more adjustable sound options than Philips’ single bass boost control.
• Best for audiophiles who want both easy sound shaping and daily convenience → Sony WH-CH520. Its EQ, DSEE, multipoint, and longer battery life cover more everyday situations, though neither model’s listed features establish it as a specialist listening headphone.
I’d choose the Sony WH-CH520 for most people comparing these two, because its longer stated battery life, EQ customization, multipoint connection, microphone, and voice-assistant support make it more adaptable across a typical day.
For audiophiles, I’d also lean Sony if the priority is shaping the sound and moving between devices. Philips is the more appealing pick if a bass boost button, closed-back design, fold-flat headband, or 3.5 mm jack matters more than those extras.
Think first about how you’ll use the headphones most often. For desk listening with a phone and laptop nearby, Sony’s multipoint feature addresses a specific inconvenience: having to manage two separate Bluetooth connections when moving between music and a call. The built-in microphone makes that pairing flexibility more useful for someone who regularly takes calls as well as listens.
Battery needs may make the choice simpler. Philips’ maximum is up to 29 hours, and its fast-charge detail gives four hours of use from a 15-minute charge. Sony lists up to 50 hours, plus up to 90 minutes of playback from a three-minute charge. These are manufacturer-stated figures, not a promise of identical runtime in every listening situation, but they give a clear comparison of the intended battery advantage.
Consider how much sound adjustment you actually want. Philips puts a bass boost button on the headphones, making one change easy to access. Sony offers app-based EQ customization and DSEE, which may suit someone who wants to adjust sound for different music or sources. Neither set of listed features tells you which headphone will sound better to every listener; preference for bass, EQ control, and the type of music you play should guide that decision.
Finally, check the connections and carrying details that matter to you. Philips lists a 3.5 mm jack and a flat-folding headband. Sony lists Bluetooth but no headphone jack, and its earcups swivel. If your use case involves a wired connection, that Philips detail is decisive. If you mainly want two-device Bluetooth use and a compact swivel design, Sony has the more relevant feature set. If you are comparing current prices, check the current price on Amazon before deciding.
