# Microphone Attributes

<figure><img src="/files/iJ1nRRpcDNAPevX5zZ3C" alt=""><figcaption></figcaption></figure>

### **1.** Microphone NFT's **ID**

Microphone ID is the ID of the NFT asset minted on the Binance Smart Chain with ERC-721 Token format.

### 2. Microphone Tier

SingSing Microphone NFT has 6 different Tiers: Wood, Bronze, Silver, Gold, Platinum, Diamond. Each tier has its own Earning Effect (random number), Resilience, Repair Cost and Additional Energy stats, that give them different values.

### **3. Earning Range**

To receive a reward after each SingSing turn, a certain score range must be met. The system uses a 100-point scale. Scores outside of the designated range will not result in a reward.

### **4. Durability**

Every time energy is used, the durability corresponds to the Resilience stat. If it reaches 0, the Microphone becomes unusable and must be repaired to full to activate additional energy. If it reaches below 1, the Microphone must be repaired in order to be used for singing. The smallest amount of repair required is 2% each time.

### **5. Level**

Show current microphone level and can be levelup with Sing tokens for unlock new feature and slight earning boost. Learn more [Microphone Levels](/singsing/platform/deprecated/sing-and-earn-deprecated/elements/microphone-levels.md)

### 6. Mint

Refers to the number of times a Microphone NFT has gone through the minting process. The maximum number of minting times allowed is 5. Learn more [Microphone Minting](/singsing/platform/deprecated/sing-and-earn-deprecated/elements/microphone-minting.md)

### **7. Resilience**

Refers to the amount of decrease in durability each time energy is consumed.

### 8. Additional Energy

"Additional Energy" allows users to have an increased energy cap of up to 12 by owning multiple Microphone NFTs. Learn more [Energy Mechanics](/singsing/platform/deprecated/sing-and-earn-deprecated/elements/energy-mechanics.md)

### 9.  Earning Effects

"Earning Effects" refers to the earning potential of each singing record. It is determined by a random and unique number and can be higher for lower tier microphones compared to higher tier microphones.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://singsing.gitbook.io/singsing/platform/deprecated/sing-and-earn-deprecated/elements/microphone-attributes.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
