JVC released the Gumy series of earphone products in 2010, and the official claim that it was the first to use a silicone shell. The HA-F150 is the earliest earphone in the Gumy series.
Gummy means candy jelly, and the texture of the HA-F150's color silicone case looks more like it. Its mold workmanship is a good level in low-cost headphones, and the transparent plastic at the inverted hole makes the overall look and feel when lying flat a bit Q, and there are some Slim monsters that are common in RPG games? However, the texture and luster of HA-F150 under normal light are not as good as photos. Many people think that it looks more like a plastic toy.
The HA-F150's outer casing is soft and can withstand extreme cross-bending bends. The first selling point is of course the comfort of wearing. However, we do not feel any special advantage compared with the general plastic earphones in actual wear. Of course, for low-cost headphones with a general mold joint degree, the use of silicone material can really avoid the discomfort caused by burrs.
HA-F150 official parameters impedance 16 ohms, sensitivity 108dB, frequency response range 16-20kHz. The neodymium magnet driver has a diameter of 13.5 mm. According to official sources, in addition to good comfort, the silicone material also has excellent acoustic response. We think this is just marketing. The effect of such a small earbud material on acoustics is not much different from plastic or wood.
We took about 60 hours of downtime on the HA-F150, and the sound did not change significantly. In the audition, we mainly use mobile sound sources such as Sony B172F, and rhythm serenade II as an auxiliary reference. And compared with the Edifier H180, innovative EP630 in-ear headphones.
The sound of the HA-F150 is too stiff, its high frequency has too obvious marks of sharpening, and the burr is very heavy. The high frequency of the H180 is slightly darker, but softer. The medium frequency density is seriously insufficient, the vocals are thin and hard, and the image and resolution of the intermediate frequency are far worse than the H180 and EP630. The sense of low frequency is too small, the texture is far less than H180, and the drum sound is just around the corner. After using the sponge cover, the high frequency becomes darker and the low frequency sense is relatively improved, but it is still a dry and hard style. The big dynamic sound is diverging and it looks very noisy. On a sound source such as an independent sound card with better driving force, the high frequency of the HA-F150 will be slightly softer, but the sound is too thin, which seriously affects the sense of hearing. Other headphones are also better at better sound sources.
The analysis of the HA-F150 is too bad, the sound is too thin and too thin, it is not a normal sound. Although the sales volume of Gumy headphones is more than 50 million, it is clear that most people choose only because of low price and unique color modeling. The ATH-FW33, which has the lowest sound quality and the worst performance of the recent sound quality, is hardly even better than the earphones attached to some portable players. It is not as good as the lower-priced H180. Unless the user is extremely disliked in-ear headphones, and the ear canal is very sensitive to plastic materials, this product is not worth buying.
