Sony WH-CH720N

The constant hum of engines on a long flight or the noise in a crowded train significantly detracts from the enjoyment of music. This model addresses that issue by providing effective noise cancellation at an affordable price point. It combines a remarkably low weight with a long-lasting battery to make daily commuting much more relaxed.

Classification and Target Audience

In the realm of wireless audio devices, the product clearly positions itself in the budget mid-range. Anyone looking at a Sony WH-CH720N review will immediately recognize the strong focus on cost-conscious professionals and students. Those seeking reliable features for everyday use but with a limited budget will find a suitable tool here.

However, the model is not designed for individuals with high audiophile demands. Those who want to enjoy orchestral pieces with maximum detail and a wide musical stage will not be satisfied with the factory tuning. Additionally, people who need extremely robust and compact travel companions for very rough environments are not the primary target audience.

Technical Features and Advantages

The manufacturer integrates its proprietary V1 chip, which also operates in a similar form in the more expensive flagship models. This component ensures reliable active noise cancelling, which effectively filters out low-frequency noise in traffic. A significant advantage in daily use is the extremely low weight of just 192 grams. This means that even after hours of wear at a desk, there is hardly any uncomfortable pressure on the head.

The battery life is very generous, lasting up to 35 hours with noise cancellation activated. With the filtering turned off, the battery lasts an impressive 50 hours. An integrated fast charging feature provides enough power for another hour of music playback after just three minutes on the power supply.

For wireless connectivity, the standard Bluetooth 5.2 is used. The headset supports the codecs SBC and AAC and also offers the practical multipoint function. This means that the headphones can remain connected to both a smartphone and a laptop simultaneously. Playback is reliably controlled via physical buttons on the right earcup, which drastically reduces misinputs. The accompanying smartphone app also offers an extensive equalizer for precise sound adjustment.

Weaknesses and Compromises

To achieve the low price, noticeable savings were made in material selection. The housing is made entirely of simple plastic and feels of low quality. The construction also cannot be folded away for space-saving storage, and a protective transport case is completely missing from the package.

Right out of the box, a very strong bass dominates the sound, heavily overshadowing the mid frequencies. As a result, voices and acoustic guitars often sound muted and unnatural. Manual correction via the app is essential to create a balanced sound profile. Additionally, high-resolution transmission standards like LDAC are completely absent, which technically limits the maximum audio quality with corresponding sources.

Conclusion & Purchase Recommendation

Those looking to buy the Sony WH-CH720N will receive an objectively very strong price-performance ratio. The combination of extremely lightweight comfort, long-lasting battery, and solid noise isolation is absolutely convincing in this price range. Anyone seeking a clear budget over-ear headphone recommendation can purchase this without hesitation. However, if finer materials and a more detailed sound from the factory are a priority, it is worth considering the alternative Sennheiser Accentum.
