Rock and roll Bell Tower capsule E300 out of the box small test

On the occasion of the spring, Berta launched its second earplug capsule E300 after the Bell E100. The earplugs are excellent in ergonomic design, shaped like capsules, and are very creative. The most special place is this. The earplugs that look small and fresh have an awkward engine.

The Berta Capsule E300 is a simple package that compresses the cost and lowers the price.

The Bella Capsule E300 uses a pair of 9mm high-performance CCAW voice coil drive units that use high-performance neodymium magnets for higher sensitivity and wide frequency response – Capsule E300 has a rated impedance of 16Ω and a sensitivity of 105dB. It is a very easy to push earplug product for 15~22000Hz.

The E300 capsule features a slim oval cavity design that meets the needs of the in-ear structure. Compared with the flat earplugs, the in-ear structure allows the catheter to penetrate into the ear canal. In addition to improving the sound insulation effect, the low frequency is more condensed and brings shocking effects.

The cavity of the capsule is ergonomically ultra-lightweight, and the weight of the ear shell is only 4g. It has no pressure when worn and has better comfort.

The capsule's excellent ergonomic design, combined with high-quality silicone earphone sets, has excellent wearing comfort.

In front of the E300's unit cavity, there is a very small orifice just below the tube. As an earplug with a moving coil unit, this hole is similar to the inverted hole design of common speakers to ensure the airflow inside the earphone cavity, ensure the pressure balance of the diaphragm, and effectively utilize the sound energy generated by the drive unit. , reducing the distortion of the audio signal, thereby enhancing the sense of low frequency and the depth of dive.

The patented “Triangle” technology is a major innovation of Bell Tower. It has good toughness, strong stability and good pull resistance, and it can effectively prevent entanglement. The E300 capsule used this wire without any accident.

The inner core of the triangle wire adopts a 20-core 6N oxygen-free copper wire design, which enhances the conduction rate, can effectively reduce the loss of the audio signal, and achieve high-purity signal transmission.

When testing this earplug, I chose the mobile phone as the test platform. The format is mainly MP3 files of 320kbps, and the songs are mainly popular in Europe and America. Sure enough, this seemingly refreshing earplug has a rock-and-roll heart, the low-frequency volume is very strong, and it is very powerful. In the European and American pop music with strong rhythm, the feeling of sorrow is still born, and such a low frequency There is not much impact on the medium and high frequency. Overall, the E300 is biased towards the bottom, and friends who like pop and rock in Europe and America should not miss it.
