Review: A fantastic, superbly built Objective2 Amp, assembled right here in the USA - So, as some of you may know already, the Objective2 amplifier was invented by a clever and quite brilliant audio engineer who goes by the moniker "NwAvGuy". The philosophy behind this invention was to create an incredible bang-for-your-buck amp with benchmark performance that hits way above its weight class. So that people on a tight budget (like me) can experience what he felt was a true piece of audiophile equipment that doesn't come with the big $$$ audiophile pricetag of other headphone amplifiers on the market. And succeed at that, he did... Now, since he made his design open source, several manufacturers have jumped at the opportunity to reproduce his design, and to make various modifications in an attempt to cater to the wants and needs of headphone lovers around the world. Ive been very impressed with Mayflower Electronics' version of the O2 amp. It has really made my HD6XX's come to life! There's no comparison to how these headphones sounded by just plugging them into my smartphone/PC. This versatile little amp really can provide ample power to even the most difficult to drive headphones on the market. And it has such a clean sound. Its very neutral, uncolored. The background is black as pitch. Dead silent. No annoying buzzing or humming that I could hear, even at high volume levels in between songs or while switching tracks/albums. The Mayflower O2 feels sleek, solid and well-built. It comes with an impressive 10 year warranty! And each unit is hand assembled and tested in-house, right here in the good ol' USA (which cannot be said for some of its competitors versions). I like supporting local businesses, and in this case they're relatively close to where I live ^_<. I've already had great experiences with their customer service and would happily and confidently buy from them again. I encourage buyers to reach out to them if they have any questions or are looking for different customization options. They've definitely made a fan out of me! Review: Impressed - I was impressed by the quality of the amplifier, but also the quality of the manufacture presentation. Instructions were very thorough, company seems to know their stuff. Hand crafted and hand tested every unit before shipping out was on the instructions paper. As for sound, my headphones is the beyerdynamic DT 770 PRO 250 Ohm. The amplifier is rated for 300 Ohm, I did have to use the gain button. But after that, the volume knob stays at around 70-80%, and that's with the 70-80% Windows volume they recommend. Overall, 5 star product. ## Features - Benchmark Performance, Un-Filtered Sound - Hand Made and Individually Tested in the USA - Connect to any PC/MAC/Phone with a 3.5mm Auxiliary Cable (Does NOT include a DAC) - Includes Power Supply - 3.5mm Output Jack ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B074MBY2GZ | | Additional Features | Lightweight | | Age Range Description | Adult | | Antenna Location | Music, Gaming | | Best Sellers Rank | #610,423 in Electronics ( See Top 100 in Electronics ) #694 in Headphone Amps | | Brand Name | Mayflower Electronics | | Built-In Media | Power Supply | | Cable Features | Retractable | | Color | Black | | Compatible Devices | PCs, MACs, Phones, and devices with 3.5mm audio input jack | | Connectivity Technology | Wired | | Control Method | Touch | | Control Type | Volume Control | | Customer Package Type | Standard Packaging | | Customer Reviews | 4.7 4.7 out of 5 stars (61) | | Enclosure Material | Aluminum, Rubber | | Frequency Range | 20 Hz - 20,000 Hz | | Headphone Jack | 3.5 mm Jack | | Item Weight | 16 ounces | | Manufacturer | Mayflower Electronics | | Model Name | language _ tag | | Model Number | 0007 | | Noise Control | None | | Number of Items | 1 | | Specific Uses For Product | Music, Gaming | | UPC | 656237168961 782290336075 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Mayflower Electronics - **Color:** Black - **Headphones Jack:** 3.5 mm Jack - **Model Name:** language _ tag - **Noise Control:** None ## Images ![Objective2 Headphone Amplifier - Image 1](https://m.media-amazon.com/images/I/31c0TZhWV6L.jpg) ![Objective2 Headphone Amplifier - Image 2](https://m.media-amazon.com/images/I/31rXu-E+a4L.jpg) ![Objective2 Headphone Amplifier - Image 3](https://m.media-amazon.com/images/I/31keMfPoufL.jpg) ## Questions & Answers **Q: Does this amplifier include the two batteries?** A: No, it just comes with a power supply. **Q: Does this need a DAC in order to work properly?** A: It needs an analog signal. So you could connect it directly to your computer using your computer’s headphone port. But I strongly recommend buying a DAC and connect it to your computer through A USB port. The O2 is an excellent amp. Adds no color to the music. And there is absolutely no noise. I use the Topping D10 DAC, available on Amazon for about US$90. The O2 is a great amp if your looking for an amp that lets you hear the music the way the arist and album producer intended it to sound. Also, it has enough power to comfortably drive headphones with as much as 600 ohms immedance. **Q: is there any difference between this amp and the Massdrop O2 Amp?** A: Hope this helps. I needed to drive Massdrop Sennheiser HD 58X Jubilee Headphones 150 ohms impedance this would not drive without distortion on games and music at standard gain (under 300 ohms). The massdrop 02 is great if pared with the massdrop DAC. Really consider your impedance. **Q: Will it work good with audeze lcd 3 (110 ohm) and sennheiser hd 800 s (300 ohm) ?** A: Yes it will easily drive both headphones. ## Customer Reviews ### ⭐⭐⭐⭐⭐ A fantastic, superbly built Objective2 Amp, assembled right here in the USA *by J***E on April 14, 2020* So, as some of you may know already, the Objective2 amplifier was invented by a clever and quite brilliant audio engineer who goes by the moniker "NwAvGuy".

I have endless audio files on my computer, so I plug the Signstek DAC into the desktop, then into the O2 amplifier, and the sound is excellent. Very clean, including at the bottom end; bass guitars and tympani sound just like they sound. I use it to listen to a wide variety of genres on the Grado line of headphones and couldn't be happier. Excellent definition and naturalness. Much fuller sound than just using a DAC. There's plenty of volume. A steal at this price. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/72157346-objective2-headphone-amplifier](https://www.desertcart.tn/products/72157346-objective2-headphone-amplifier) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-04-26*
