Let’s get right to it! The sound produced by the Liberty 4 Pros is powerful! You get a soundstage with headroom to spare, boomy bass, punchy mids, and output that has you rarely needing to raise the source volume higher than around 65% of max.
Though not the highest durability rating, the Liberty 4 Pro should be able to handle whatever workouts you throw at them with an IP55 rating for water and dust ingress. They ship with Bluetooth 5.3 and LDAC codec support for hi-res wireless audio, along with Spatial Audio support. You get Easy Chat, which is an audio ducking feature that “hears” conversation and lowers the audio volume so you can carry on a conversation.
Liberty 4 Pro noise cancelling earbuds boast 7 sensors—6 sound sensors and 1 barometric pressure sensor—to capture noise from every angle. From planes to trains, enjoy a serene journey with 3× stronger noise reduction.
These noise cancelling wireless earbuds adapt to your ever-changing environment every 0.3 seconds, ensuring optimal, seamless noise reduction around the clock.
The touch bar and display let you fine-tune the noise-cancelling levels of these wireless earbuds at any time with a simple swipe on the case.
Feature the enhanced ACAA acoustic architecture, a 10.5mm bass driver, a titanium-coated tweeter, and a digital crossover for peak driver performance. Indulge in crisp, full-bodied sound perfected with nuances.
Liberty 4 Pro noise cancelling earbuds charge 2× faster than the previous models with the 5C battery. A 5-minute recharge offers 4 hours of playtime. Enjoy up to 10 hours between charges, extendable to 40 hours with the case.
With a noise reduction algorithm and six mics, these wireless earbuds deliver clear calls wherever you are. Plus, a wind noise reduction algorithm ensures seamless, hassle-free communication, rain or shine.
At Martreza, we strive to provide a seamless shopping experience for our customers. We understand that sometimes items may not meet your expectations, and we are here to assist you with returns and refunds according to the following policy:
1. Returns:
Eligibility: To be eligible for a return, the item must be unused, in its original packaging, and in the same condition as when you received it. Some products may be exempt from returns due to hygiene or safety reasons, such as perishable goods or intimate apparel so make sure to check the return period before making a purchase to avoid any confusions.
Timeframe: You have varied days as shown below on the table from the date of delivery to initiate a return request. After this period, we will not be able to accept returns.
Return Process: To initiate a return, please go to the orders page on you profile and press on the return request to initiate the process then provide your order number, item details, and reason for return. Our team will guide you through the return process and provide instructions for shipping the item back to us.
Return Shipping: Customers are responsible for the cost of return shipping unless the reason for the return is due to operational error or a defective product processing on our side.
2. Refunds:
Refund Eligibility: Once we receive the returned item and verify its condition, we will process the refund. Refunds may be issued to the original method of payment or as different credit, depending on your preference.
Processing Time: Refunds are typically processed within two business days after confirming the validity of the returned item. However, it may take additional time for the refund to appear in your account, depending on your financial institution.
Partial Refunds: In some cases, partial refunds may be issued for items that are returned in a used or damaged condition, or for returns that do not meet the eligibility criteria outlined in our policy.
Deductibles or Processing fee: If a customer initiates a return based on preference rather than an issue with the item, a processing fee will be deducted from the refund to cover vendor compensation and operational costs.
