With stage-filled sound and beautiful shining style, the SednaEarfit Crystal solves the problem of long-wearing and falling earphones while maximizing the potential of BOSE TWS Review: 買って正解🙆‍♂️ - ・素材が柔らかめで肌当たりが良い → 耳にしっかりフィットしやすい → 長時間でも疲れにくい ・シール性が高い → 低音の量感・キレが増す → ANCの効果が活きる → ボーカルも前に出やすく、クリア感が出る ・ハウジングとの密着が良い → 音場感が広がる → 微妙な高域の抜けが良くなる 耳垢とか汚れつきやすいけど、そんなの気にならないくらい、いい買い物したと思います。 Review: イヤーピースを変えてやっと価格相応なのでイヤーピースとしてはかなりの出来 - QuietComfort Ultra Earbudsが価格相当の音質になるくらいですかね、、、 n5 hybridにつけれないかと思って購入したのですが、結論を言うとつけれますが固定が弱い為おすすめはできません。 ほぼBOSE以外にはつけれないと思っていたほうがいいです。 QuietComfort Ultra Earbudsに使用してみた所、低域意外は平凡だった音が全体に渡り価格相当の音質になったと感じました。 ※BOSEの音基本的に私には合わないので、、、 普段使う事がなかった為、多少使用頻度は上がるのかな？位の気分です。 また、密着性も上がる為ノイキャンが更に効く様になりますが、ホワイトノイズが聞こえやすくなりハウリングもしやすくなる為この辺は注意ですね イヤーピース自体は非常にいいのですが、使える機種が使っても他のメーカーの同価格帯のイヤホンと同じ位の音質になる位なので別メーカーの同価格帯のイヤホンを持っている場合は微妙かもしれません。 勿論人により好みは変わりますのでBOSEの音が好きな人にはおすすめ出来るかと思います。 ## Features - Earpieces for BOSE QuietComfort Series: "SednaEarfit Crystal for BOSE Earbuds" are earpieces developed for use with BOSE's completely wireless earphones (TWS) Based on the fundamental design derived from the analysis of 788 ear canals, and the use of premium German LSR (liquid silicone rubber) which has the characteristics required for high level earpieces, we have achieved a high level of fit, low pressure, high sound insulation, high durability, and low irritation - 【Premium German-made Premium LSR Adopted】The adopted premium LSR material has unique properties such as excellent heat resistance, oxidation resistance, surface tension, low temperature flexibility, and good dielectric properties.
