《Stereophile》2019音响器材推荐：Focal 三款耳机榜上有名

体验中心

知名音响杂志《Stereophile》的“Recommended Components”是音响界含金量极高的评价，被很多音响厂商和发烧友所认可。该奖项评选内容包括唱机、CD机、数字处理器、环绕声器材等。2019上半年，“Recommended Components: 2019 Edition”已经揭晓，法国 Focal Clear、Focal Elear、Focal Utopia Reference 三款耳机成功入围。



Focal Clear


法国高端音响品牌 Focal 2017年推出Clear开放式耳罩耳机，定位在Utopia与Elear之间，明显展露经营中高阶耳机市场的决心。Focal Clear与Focal Utopia与Elear一脉相承，搭载Focal 特别的 40mm的铝镁合金单体。这个单体有三大特点：



第一，它采用了同Utopia与Elear一样的内凹设计单元。相较于同尺寸的凸盆式单元，内凹设计的音圈直径可以做得更小，如此一来减少音圈质量，让单体变得更容易推动。直径25.5mm、高5.5mm的单层纯铜线圈，而且没有套筒支撑，让线圈在轻盈的质量下可以产生强大的磁力。



第二，就是单体振膜以铝镁合金为材质，这是因为Focal发现铝镁合金的共振点刚好在人耳可听频段之外，而且刚性又够，因此Focal Clear与Elear一样，单体振膜以铝镁合金为材质，至于旗舰级的Utopia，当然就是采用Focal最为著名的铍振膜。



第三，就是单体振膜采用M型设计，在单体周围的地方拥有M自形的弯折，与极薄的悬边连接。Focal声称这样的设计可以让单体拥有极为优异的暂态反应，有利于重现高频细节。


测评员评论：
Described by HR as "Focal's newest, handsomest, most comfortable, and, perhaps, most musically satisfying headphones," the Clears are dynamic, circumaural, and open-backed, built on a solid aluminum yoke with a soft leather headband. They use the same 40mm aluminum-magnesium domes and formerless voice-coils as the 33%-less-expensive Focal Elears, yet here those coils are pure copper rather than copper-clad aluminum; their impedance is 55 ohms, their sensitivity 104dB—clearly drivable by an iPhone. Three cords are included: one with an XLR for balanced use, one with a ¼" plug, and one with a 3.5mm plug. According to HR, with the Clears, "large-scale dynamics operated in marvelous ways," and they avoided the occasional glare experienced with Focal's flagship 'phones, the Utopias. For pure listening pleasure, the "absolutely comfortable, museum-quality-beautiful" Clears are Herb's "real-world reference." "Springy cord is a hassle to manage," notes JI. (Vol.41 No.6 WWW)




Focal Elear


Elear在Focal的Hi-End系列耳机里面属于中坚产品，采用40mm“M型凸盆”铝镁合金全频单元，其市场定价比Utopia要便宜得多。40mm“M型凸盆”铝镁合金全频单元的安装位置不是位于耳机腔的中间位置，而是稍微靠前的，目的就是追求更接近于听音箱的效果。



铝镁合金振膜也是Focal沿用多年的产品，压铸方式和铍是一样的，只是不需要高温锻造，而且材料本身的价格也便宜得多，工艺也相对简单，但其硬度相比起常见的铝合金、钛金属、丝膜等材质要高。因此，这种铝镁合金振膜单元从总体成本到性能之间能取得一个很好的折中点。

测评员原文：
Offered as a comparatively affordable alternative to Focal's Utopia headphones ($3999), the Elears are made of slightly less costly materials—most notably an aluminum-magnesium alloy instead of beryllium for the domes of its drivers, and aluminum instead of carbon fiber for the yoke. As HR discovered, "both Focal models have delicate, beautifully rendered trebles, and . . . both sort out complex music better than any of their competitors." But he heard from the Elears a slightly thicker sound in the lower midrange and upper bass—qualities that did not always work against the less expensive 'phones: the humbler dome "adds an extra, enjoyable measure of tonal color that's absent from the more pure and empty-sounding Utopias."




Focal Utopia Reference


凭借在HI-END领域几十年的经验，Focal进入高端发烧耳机圈推出大乌托邦耳机将Focal技术精华的铍振膜技术（Focal是世上唯一有能力可以在自家厂房生产纯铍单元振膜的大型音响厂家）运用到了耳机振膜上，再加上Focal 对音频多年的出色调音，因此被众多耳机老烧誉为音色最好的动圈耳机也就不足为奇了。



测评员原文：
The fully open-backed, circumaural Focal Utopias are designed around proprietary beryllium-dome full-range drivers that, uniquely, have no voice-coil formers: each coil is fastened directly to its dome, in a crease near its surround. The yokes are made of carbon fiber, and the earcups and headband are covered with lambskin. HR described the Utopias as capable of producing "a gut-level realism that is rare in high-end audio," adding that the Focals are "lightning-fast, extremely open, and profoundly uncolored."
