عن معاوية رضي الله عنه قال: سمعت رسول الله يقول: المؤذنون أطول الناس أعناقا يوم القيامة .
It is narrated from Sayyiduna Muawiyah (may Allah be pleased with him) that I heard the Messenger of Allah (peace be upon him) say: "The one who gives the Adhan will have a longer neck than all other people on the Day of Resurrection."

عن عبد الله بن عبد الرحمن بن أبى صعصعة أن أبا سعيد الخدري رضى الله عنه قال له: إني أراك تحب الغنم والبادية ، فإذا كنت فى غنمك أو باديتك فأذنت للصلاة فارفع صوتك بالنداء ، فإنه لا يسمع مدى صوت المؤذن جن ولا إنس ولا شيء إلا شهد له يوم القيامة قال أبو سعيد: سمعته من رسول الله ﷺ
Sayyiduna Abdullah bin Abdur Rahman bin Abi Sa'sa'ah narrates that Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) said to him: "I see that you like goats and the wilderness, so when you are with your goats or in the wilderness and you call the Adhan for prayer, then raise your voice in the Adhan, because the jinn, humans, and other beings who hear the Mu'adhin's voice until the last part will bear witness for him on the Day of Resurrection." Sayyiduna Abu Sa'id (may Allah be pleased with him) said, "I heard this from the Messenger of Allah (peace be upon him)."
Reference: Sahih Bukhari, Book of Adhan, Chapter on Raising the Voice in the Adhan, Hadith No: 609.
Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Prophet (peace be upon him) said:
إن الله وملائكته يصلون على الصف المقدم ، والمؤذن يغفر له بمد صوته ، ويصدقه من سمعه من رطب ويابس، وله مثل أجر من صلى معه .
"Indeed, Allah and His angels send mercy upon the first row. And the Mu'adhin will be forgiven because of his loud voice. And whoever hears his voice in dryness or wetness will testify for him, and there is a reward for him like the reward of the one who prayed (after hearing the Adhan)."

Imam Mundhiri has declared it "Jayyid" (good).
