Outdated Product
An on-ear headset of a confident mid-range with a view to comfortable everyday wear. The model has a foldable design with an adjustable headband and swivel cups. Its connection to audio sources is carried out via the Bluetooth v5.3 wireless communication protocol, but the headphones cannot pair with several devices at once. The headphones have 40 mm dynamic drivers with M.O.C.I. membranes. (made of nanomycelium and carbon fiber). Fstyler's signature sound ensures clear reproduction of high frequencies and mids, as well as deep elaboration of the bass component of the sound palette. In addition, the A4Tech Fstyler BH350C features active noise cancellation ANC. And for clearer speech transmission when communicating on a paired phone, the headset received a microphone system with ENC noise re...duction. In the mode of listening to music with active noise reduction, the battery life of the headphones can reach 30 hours, without noise reduction - over 50 hours. Moreover, during the 15-minute “charging” procedure, the headset accumulates enough charge for subsequent 3-hour operation.

Popular questions

Verified 9 september, Olexandr Cherkashchenko

Will the charge last for several days of regular listening?

A4Tech Fstyler BH350C can last for several days without recharging. Up to 50 hours without ANC is claimed, while testing at 40% volume yielded around 53 hours without noise cancellation and 39 hours with it. Fast charging is also useful on the go.Source:SpecificationsExpert reviews

Can they be used with a cable if the battery runs out?

A4Tech Fstyler BH350C do not support a wired connection. Listening requires a Bluetooth source and a charged battery, so they are less convenient as universal headphones for stationary equipment or flights without the possibility of recharging.Source:Expert reviews

Is the A4Tech Fstyler BH350C convenient to carry in a bag?

The model is convenient to carry: the earcups swivel and the design folds, making the headphones flatter and more compact. No separate case is included; only a short USB-A to USB-C cable and documentation are provided.Source:Expert reviews

Can the A4Tech Fstyler BH350C handle subway noise?

For subway use, the ANC is rather weak: it eliminates office hum and slightly muffles street noise, but noticeably lets loud transit sounds through. With noise cancellation enabled, wind can even sound louder, so this model is better suited for home or a quiet office.Source:Expert reviews

Are the A4Tech Fstyler BH350C suitable for music with pronounced bass?

For bass-heavy music, this is not the best choice. The sound is clean, and vocals and instruments come through clearly, but the low frequencies are weak and may not deliver the expected punch in hip-hop, electronic, or heavy music.Source:Expert reviews

Will I be heard clearly on work calls?

For frequent calls, the A4Tech Fstyler BH350C should be considered with caution. In the review, the voice captured by the built-in microphone was described as distant and muffled, and even indoors, it was necessary to speak louder. ENC does not make this model a strong choice for outdoor conversations.Source:Expert reviews
