If you want wireless earbuds for calls and everyday listening, choose Lenovo LP40; if you need a protective storage case for compatible JBL earbuds, choose RLSOCO Carrying Case. For a call center, Lenovo is the relevant choice because it includes earbuds and microphones; RLSOCO is an accessory case, not a headset.
These products do different jobs, so the deciding question is whether you need audio gear or protection for a specific pair of earbuds. Neither is a substitute for the other.
Lenovo LP40 vs RLSOCO Carrying Case at a Glance
• RLSOCO Carrying Case’s biggest strength: a hard EVA storage case designed to protect compatible JBL earbuds and hold small accessories. Trade-off: it includes no earbuds and is not listed as compatible with Lenovo LP40.
• Choose Lenovo LP40 if you need wireless earbuds for calls, music, or workouts.
• Choose RLSOCO Carrying Case if you already own one of the supported JBL models and want a separate protective case.
Lenovo LP40 is a pair of true wireless earbuds with Bluetooth 5.1, touch controls, and a built-in microphone in each earbud. You can use one earbud or both, which gives you some flexibility for listening and calls. The listed design is semi-in-ear, with curved surfaces intended to sit gently in the ears. For someone looking for earbuds that can move between music, calls, and voice-assistant controls, that combination is more useful than a case-only accessory.
The LP40’s call-related features make it the only sensible choice of these two for a call center. Its microphones and noise-reduction feature are described as helping voice calls, but the available information does not establish how well it handles constant background noise or a full work shift. The listed music playback time is up to five hours, and the earbuds take about 1.5 hours to charge. That gives you concrete limits to consider if you expect long stretches of continuous use.

RLSOCO Carrying Case is a storage and protection accessory, sold without earbuds or other accessories. Its listed compatibility covers several JBL models, including Vibe Beam, Vibe Beam 2, Vibe 200TWS, Wave 200TWS, Tune 130NC TWS, Tune 230NC TWS, Tune Beam, and Tune Beam 2. If you own one of those models, the case is intended to give the earbuds and their charging case a dedicated place in a bag or pocket.
The shell uses high-density EVA with fiber material. The product information describes it as protective against knocks, shocks, scratches, dust, and water. Those features make sense for someone who regularly carries compatible earbuds alongside other items. The case is also listed as weighing 0.04 kg, though that figure alone doesn’t tell you its exact shape or how much room it will take up in a particular bag.
This case is for someone who already has a supported JBL model and wants added storage protection—not someone shopping for earbuds, microphones, or call-center audio. Compatibility is the key trade-off: Lenovo LP40 is not among the models listed, so I would not assume the case fits it. If you need a pair of earbuds, RLSOCO cannot meet that need on its own.
• Need wireless earbuds for calls → Lenovo LP40. It includes two earbuds and a microphone in each; RLSOCO is a case only.
• Need a protective home for compatible JBL earbuds → RLSOCO Carrying Case. Its EVA and fiber construction is designed for storage and protection.
• Shopping for a call-center option between these two → Lenovo LP40. It is the only one with call and audio features, though its listed music time is up to five hours.
• Want to use one earbud or both → Lenovo LP40. The product information describes a dual-ear design that can be used separately or together.
• Need touch controls for music, calls, or a voice assistant → Lenovo LP40. Touch operation is part of its listed feature set.
• Want a case for a listed JBL model and small accessories → RLSOCO Carrying Case. Compatibility includes several JBL earbuds, plus cable and ear-tip storage in the product description.
• Need a case specifically confirmed for Lenovo LP40 → Neither is clearly the answer. The RLSOCO compatibility list does not include LP40, and the Lenovo listing describes its own charging and storage case rather than a separate protective case.
• Looking for the best true wireless earbuds for call center use, or the best sports earbuds for call center use → Lenovo LP40 is the relevant pick here. It is described for calls and sports, but the data does not establish noise handling in a busy workplace or long-session comfort.
• Searching for memory foam ear cushions headphones for call center work → Neither matches that description. LP40 is a semi-in-ear earbud design, while RLSOCO is a carrying case.
My Verdict
I’d choose RLSOCO only if I already owned a compatible JBL model and wanted a separate protective case. For a call-center audio need, my recommendation is Lenovo LP40—not because it is a dedicated work headset, but because the RLSOCO case cannot provide audio at all.
The listed compatible models are JBL earbuds, and Lenovo LP40 is not named. I would not assume the LP40 charging case fits.
No. It is a case-only product; earbuds and accessories are not included. It is meant to store compatible JBL earbuds and accessories.
It has a microphone in each earbud and listed call noise-reduction features, so it is the relevant option of these two for calls. Its listed music playback time is up to five hours, and the supplied information does not establish performance in a noisy call-center environment.
Choose based on what you already own and need: LP40 provides wireless earbuds, while RLSOCO provides storage protection for compatible JBL earbuds. The case’s description highlights carrying it in a pocket, purse, or bag, but it cannot replace earbuds.
