If you want wired, over-ear headphones for focused listening while jogging in a controlled setting, choose Amazon Renewed Audio-Technica ATH-M30x; if you need a wireless in-ear monitor system for jogging with a beltpack and transmitter, choose LMBGM A9. The practical difference is clear: one plugs directly into a headphone jack, while the other sends audio wirelessly from a separate transmitter.
Amazon Renewed Audio-Technica ATH-M30x vs LMBGM A9 at a Glance
• Amazon Renewed Audio-Technica ATH-M30x: 40 mm drivers, an over-ear design, and sound isolation are its strengths; its main trade-off is a wired connection.
• LMBGM A9: UHF wireless transmission, under-5 ms latency, and a metal transmitter/receiver setup suit monitoring; its main trade-off is managing separate components and a stated 5–7 hours of battery life.
• ATH-M30x makes more sense for someone who wants a straightforward wired listening setup and can keep its cable out of the way.
• LMBGM A9 fits someone who needs a wireless monitor connection and accepts the beltpack and transmitter that come with it.
• For jogging, choose based on how you’ll handle the cable or beltpack—not on an assumption that either system is designed specifically for running.
The ATH-M30x is a wired, over-ear headphone with 40 mm dynamic drivers. Its sound is tuned for detail and mid-range definition, which may suit listening where vocals and other mid-range elements need to remain easy to follow. A listed frequency range of 20 Hz to 20,000 Hz describes its coverage, but it does not by itself tell you how you will perceive every recording.
Its circumaural cups sit around the ears, and the design is described as providing sound isolation in loud environments. That makes the M30x worth considering for focused listening when reducing surrounding sound matters. The single-side cable exit keeps the cord coming from one side rather than both, and the headphones fold down for more compact storage. Those details can help with packing, though they do not remove the practical drawback of having a cable attached while moving.
This is an Amazon Renewed product: the listed description says it is pre-owned or refurbished and professionally inspected and tested to work and look like new. I’d consider it for stationary listening, travel, or a setup where a direct wired connection is preferred. For jogging, the cable and over-ear fit are meaningful compromises; nothing in the listed details identifies it as a sports-specific design.

Who should skip this: Skip the M30x if you need wireless freedom or want to avoid managing a headphone cable while running.
LMBGM A9: Who It's For
The LMBGM A9 is not simply a pair of wireless headphones. It is a UHF in-ear monitor system built around a transmitter and beltpack receiver, with ear-rest headphones included. The system supports mono balanced XLR and unbalanced TS inputs, so its intended use is tied to an audio source connected to the transmitter. That makes it a more specialized choice than a conventional wireless headset.
Its listed latency is under 5 ms, a specification aimed at keeping monitored audio closely timed with the source. The system also lists 24-bit/96 kHz audio, a 20 Hz–20 kHz frequency response within ±0.5 dB, a signal-to-noise ratio of at least 94 dB, and a dynamic range of at least 103 dB. These figures describe its stated audio capabilities; they don’t guarantee that every source, recording, or listening situation will sound the same. The built-in limiter is intended to help avoid distortion when the input level is too high.
Who should skip this: Skip the A9 if you want a simple pair of headphones without a separate transmitter, beltpack, and charging routine.
• Best for a direct wired connection → Amazon Renewed Audio-Technica ATH-M30x. It connects through a 3.5 mm headphone jack and does not need the A9’s transmitter-and-receiver setup.
• Best for UHF wireless monitoring → LMBGM A9. Its transmitter sends audio to a beltpack receiver, with latency listed below 5 ms.
• Best for mid-range detail in a conventional headphone design → ATH-M30x. Its tuning specifically emphasizes detail and mid-range definition.
• Best when input connections matter → LMBGM A9. It supports mono balanced XLR and unbalanced TS input.
• Best for folding down for storage → ATH-M30x. Its collapsible design is a practical advantage when packing headphones away.
• Best for a metal-cased transmitter and receiver → LMBGM A9. The system’s listed construction emphasizes metal casing that is described as resistant to accidental drops.
• Best for jogging without a headphone cable running to the audio source → LMBGM A9, with caveats. Wireless transmission removes that particular cable connection, but you still have a beltpack and battery to manage.
• Best for listening without charging the headphones → ATH-M30x. It is wired, whereas the A9 lists a rechargeable system with 5–7 hours of battery life and a three-hour charge time.
Buying Considerations
The A9 avoids a direct wire between the transmitter and the in-ear receiver, but it is a system rather than a simple wireless headset. The transmitter needs an audio input, and the beltpack receiver needs to be worn. The stated battery life is 5–7 hours, so a longer outing or repeated use means accounting for charging. The included packing list names the transmitter, receiver, ear-rest headphones, a 6.35 mm adapter, charging cable, and manual; it does not describe a phone-specific wireless connection.
Also consider whether you need headphones for listening or a monitor system for a connected audio source. The ATH-M30x has a 3.5 mm jack and is designed as an over-ear wired headphone. The A9’s XLR and TS inputs, low-latency claim, and beltpack are more relevant when monitoring audio from compatible equipment. Those are different jobs, even though both products let you hear audio.
If you are comparing them as a wireless headset for jogging, the A9 is the closer match on connectivity, but the beltpack and transmitter make it less straightforward than a typical running headphone. If your search is for the best crystal clear calls gaming headphones for jogging, neither data sheet establishes call performance or gaming features. Likewise, the A9’s push-button volume control does not make it a touch control wireless headphones for jogging; its listed controls are push buttons, and the M30x is wired.
Finally, weigh portability against the components involved. The M30x folds for storage, while the A9’s package includes several separate pieces. The M30x’s stated weight is 7.8 ounces; no corresponding system weight is provided for the A9, so there is no fair basis here to compare the total carrying weight.
In my opinion, I’d choose the Amazon Renewed Audio-Technica ATH-M30x for straightforward listening: its wired design, 40 mm drivers, mid-range emphasis, and folding construction make its role easy to understand. But for jogging specifically, I would lean toward the LMBGM A9 only if I needed its UHF monitor setup and could comfortably manage the beltpack, transmitter, and battery. Neither is an obvious all-purpose running headset, so I’d match the choice to the actual audio source and how much equipment I’m willing to carry.
FAQ
No Bluetooth connection is listed. The A9 uses UHF wireless transmission between its transmitter and beltpack receiver, with mono balanced XLR and unbalanced TS inputs specified for the transmitter.
Its listed battery life is 5–7 hours, and a full charge takes three hours. Those figures make charging and run time relevant considerations for extended or frequent use.
The ATH-M30x is described as having a circumaural design that provides sound isolation, and its tuning emphasizes detail and mid-range definition. The A9 lists audio specifications including under-5 ms latency and a 24-bit/96 kHz format; those describe its stated system capabilities, not a direct listening comparison.
