Problem: Article: The ultimate earphone test involves the music you know best. These tracks are typically what you want the earphones to play well. In addition, you know how these tracks should sound, so you can identify any audio flaws caused by inferior earphones. You can create a playlist in a music program such as iTunes. It doesn't matter what genre you use as long as you know the songs well. Search online to find music recommended for testing, such as at https://www.whathifi.com/features/10-best-tracks-to-test-your-headphones. You can also download non-music audio files to give your earphones more accurate tests, such as at https://www.audiocheck.net/soundtests_headphones.php. Using multiple genres helps test the full range of sound earphones can produce. Different genres of music may focus more on higher or lower pitches. Orchestral music is often used for a wide range of pitches. Rock music can be good for higher pitches, while jazz music is often helpful for testing lower pitches. For higher pitches, look for loud vocals, guitars, and drums. For lower pitches, seek out low, steady bass lines. If you don't listen to a wide variety of music, that's okay. It's more important for you to know the songs well so you can decide if the earphones give you the sound profile you desire. Downloading the playlist onto your device allows you to test the earphones as soon as possible. You may be able to bring a phone or an MP3 player into the store with you so you can test earphones before you buy them. Plug the earphones into your device and play your music. Keep any online audio tests bookmarked on your phone or computer so you can access them without downloading any files. Many times you can't test earphones before buying them. When this happens, make sure the store has a good return policy in case you are dissatisfied with the sound quality. Plug the earphones into your device and go through the tests 1 by 1. Be sure to check the overall audio quality as well as its range. Make sure you are able to hear your playlist fully and without obnoxious buzzing. By doing this, you have a better chance of finding earphones that are right for you. The only way you can really test earphones is by using them.
Summary: Make a playlist of your favorite music. Test earphones with multiple genres of music if possible. Download music playlists onto an electronic device. Listen to the music through the earphones.

Problem: Article: "A lot" is a noun phrase (an indefinite article a + a noun) that functions as an adjective to refer to the quantity of something. This makes it like any other noun phrase, such as "a wagon" or "a puppy," and it is always spelled as two words. For example: I have a lot of money. I have a lot of burritos. I have a lot of Bratz dolls. I like you a lot. "A lot" is often used in informal conversation to describe the quantity of something, but it is usually considered too colloquial for use in formal prose. Some people prefer to use a lot to describe quantities for collective nouns, or things that cannot be counted individually, such as sugar or water. For example: "There was a lot of sugar on the floor." It may be preferable to use other words, such as "several," "many," or "a great deal of" when referring to count nouns (things that can be counted individually). Allot is a verb, something you do, rather than an adjective that describes something. For example: He was allotted three feet of space to set up his art stall. I will allot these lottery tickets to my friends. It no longer exists as an acceptable word in English. It was taught in the U.S. school systems in the 60's through the 90's which may be causing some confusion between generations. If you catch yourself writing alot, even in informal situations, rewrite it as a lot as it is the accepted appropriate use.
Summary: Use the informal phrase "a lot" when you wish to describe quantity. Understand that "a lot" is often considered slang. Use "allot" when you are referring to giving out, apportioning, dividing or granting something. Refrain from using "alot". Practice your usage.
