To identify the odd one out among the times \(15:46\), \(12:37\), \(7:22\), and \(8:33\), let’s analyze the relationship between the hour and minute values.

1. **15:46**: Sum of digits: \(1 + 5 + 4 + 6 = 16\)
2. **12:37**: Sum of digits: \(1 + 2 + 3 + 7 = 13\)
3. **7:22**: Sum of digits: \(7 + 2 + 2 = 11\)
4. **8:33**: Sum of digits: \(8 + 3 + 3 = 14\)

The sums are:
- 15:46 → 16
- 12:37 → 13
- 7:22 → 11
- 8:33 → 14

The odd one out is **15:46**, as it has the highest digit sum among the options.
