EN： In consumer tech, 'open-fit earbuds' refer to headphones designed to rest in the outer ear without creating a tight seal with silicone ear tips (unlike 'in-ear' monitors).

EN： In consumer audio technology, earphones are broadly divided into 'open-fit' (such as standard AirPods) and 'in-ear' or 'canal-type' designs (such as AirPods Pro). Open-fit designs prioritize all-day comfort and situational awareness by not sealing the ear canal, whereas in-ear models use silicone or foam tips to achieve passive noise isolation.
中文： 在消費性音訊產品中，耳機主要分為「開放式／平頭式」（如標準版 AirPods）與「入耳式」（如 AirPods Pro）。開放式設計不會封閉耳道，主打全天候佩戴舒適度與環境音警覺性；而入耳式則使用矽膠或海綿耳塞套深入耳道，以達到被動降噪與低音密封的效果。

中文： 動詞「call」可用於不完全及物動詞句型：「call + 受詞 + 受詞補語」（稱呼某人／某物為……）。此處「them」為受詞，後方引號內的長名詞片語則擔任受詞補語，補充說明受詞的性質或稱號。
Critics called the movie a masterpiece of modern cinema.
影評人稱這部電影為現代電影的傑作。
EN： When the subject of the adverbial time clause is the same as the main clause subject, 'while' can be directly followed by a present participle (-ing), omitting the subject and the auxiliary verb (e.g., 'while commuting' instead of 'while they were commuting').
中文： 當由「while」引導的時間副詞子句與主要子句主詞相同時，可省略主詞與 be 動詞，直接保留現在分詞（-ing）形成分詞簡化句（即「while commuting」相當於「while they were commuting」）。
He often listens to podcasts while jogging in the park.
他常在公園慢跑時聽播客。
EN： In consumer tech journalism, reviewers frequently test open-fit earbuds during 'commuting' (taking subways, buses, or trains) because ambient noise isolation and stability under sudden movement are critical real-world benchmarks for earbud performance.
中文： 在科技產品評測中，評測人員經常特別測試耳機在「通勤」（搭乘地鐵、公車或火車）時的表現，因為環境噪音隔離能力與在顛簸晃動下的配戴穩定性，是消費者評估真無線耳機日常實用度的關鍵指標。

EN： In wireless earbud design, 'stability wings' (also known as ear hooks or wingtips) are flexible silicone fins meant to lock inside the ear canal's ridges. Open-fit earbuds like base AirPods lack these, making them comfortable for casual wear but prone to falling out during high-intensity training or running.
中文： 在無線耳機設計中，「stability wings」（固定耳翼，也稱耳掛或翼尖）是彈性矽膠結構，用於卡在耳廓內固定耳機。像標準版 AirPods 這類半開放式（open-fit）耳機沒有此設計，因此佩戴較無壓迫感，但在高強度訓練或跑步時容易滑落。
