The phrase "wast ones ears in" sounds archaic and unfamiliar to modern English speakers. However, it is simply an old-fashioned way of saying "waste one's time on." The IPA phonetic transcription of this phrase would be /weɪst wʌnz ɪərz ɪn/. It's important to note that the "wast" is the archaic spelling of "waste," and "ones" is pronounced as "wʌnz" to indicate the plural possessive form. "Ears" is pronounced as "ɪərz" due to the presence of the diphthong "ea."
