Manual of product CD311
Editorial note
The Acme United CD311 headphones stand out for their exceptional audio quality thanks to a sensitivity of 104 dB and a wide frequency range of 20 to 20,000 Hz, providing an immersive listening experience suitable for all music genres. Their in-ear design ensures prolonged comfort, allowing for long listening sessions without discomfort. Aesthetically, these headphones feature a modern design in black finish that easily integrates with different styles, although this color may not suit everyone's taste. With a 1.2-meter cable, they offer flexibility of use, even if some users might find this length insufficient for their needs. However, wired connectivity can be a constraint for those seeking greater freedom of movement, while the lack of additional features, such as an integrated microphone or volume controls, limits the experience for users who use their headphones for calls. Despite these drawbacks, the value for money remains attractive, supported by Acme United's reputation for innovation and durability.Score details
