The old-man –
Pros: This is a follow up of my previous review.
After additional time with my SAROS C740S wireless headphones I want to report I am more pleased than first reported. I have been using them quite frequently. Have lots of music. About to fill up a 128GB TF(SD) disk with MP3 music. My comments result from a comparison of three modes, from streaming service to actual CD. The music service I used is one of the good ones but like almost all they stream HD about 160kbps compared to 320kbps for MP3. Did my research on this over the internet so you can check that out if you desire.
My original report commented that they were not $300 Concert Headphones, however I am finding that they are responsive over the broad frequency range. My first review was on streaming internet music in wireless mode only. I later found this is not the best music I have heard so I have since tested them three ways. I decided to use my own CD (pardon my taste), Chumbawamba Creepy Crawling track 8. This has deep bass Guitar for the test. I tested 1-Streaming Music Service over Desktop PC with SAROS headphones wired through sound card plug; 2- Using a copy of this song from my CD in Lame MP3 format; and 3-Acutal CD playing track 8 Creepy Crawling on my Desktop CD /DVD player. RESULTS: the streaming service (1) I first used in my original review was heard with muted bass, missing some sound quality that makes the music come alive. Next was my MP3 copy off my CD, Very good. Nice bass response on guitars and heard better background music. The BEST was the actual CD. Not a great deal of difference between CD and MP3 but it still was noticeable. WOW! Very noticeable difference between CD (3) and music streaming service (1). The SAROS C740S gave me all I needed off the CD to change my original review comments. This 5 star rating also includes my evaluation of product quality versus price. Cons: None so far Overall Review: Excellent product for the price

Pros: This headset’s specs are similar to other headsets I bought in the past. The noise cancelling is a good feature. And I got a GREAT deal on the price. Cons: Like other wireless headsets I have purchased. The headband is of cheap construction and I will break in a few years with my HUGE noggin. Overall Review: If you got a smaller head…it is a good purchase.
If you got it cheap…again yes.

Pros: Light weight and low price. I am not an audiophil. The quality seems ok. Cons: Noise cancellation is poor. I use it in YMCA while walking with a basketball court down below. This shields about 50% noise. I have a Boltune headset that shields about 90%. Overall Review: A buy only if high noise cancellation is not a priority.

Pros: I like this Rosewill Saros c7405 was 20.00 when purchased Nov 2023 on sale.
I also like the music quality it produces, the fact it came with a protective cloth bag, and a 3.5mm analog audio cable for use when the battery is dead. It also came with a USB cable for charging the built in battery.
Sure, it is not equal to the 350.00 brand-name headphones, but it sure sounds great and very useful for using at the gym, placing in my gym bag, and not worrying if I damage it or lose it considering I can buy 16 more and not pay what 1 costs of the famous name brand.
The ANC works reasonably well and does indeed lessen other sounds in the immediate environment when I use these for music or phone calls. Everyone I call using these headphones says I sound the same when I ask for a sound quality evaluation.
It has oblong padded ear pads that cover my complete ear and therefore do not push on my ear flaps and do not cause discomfort. It also seals in the music to my ears.
They feel good, sound good and look good with the small logo on each side which will cause others to wonder what new product they need to learn about. Cons: Very few cons if any. Maybe 1 con is that it does not include a hard case with a zipper but there are so many available online that will do if you need to have one. I dont. Overall Review: Yes, give it a try. You won’t regret it.

Pros: – Has a lot of bass compared to my other cheap Chinese headphones.
– Bluetooth works well
– Other people say the noise cancelling isn’t that good, but I disagree…I think the noise cancelling works pretty well.
– You don’t have to put them INSIDE of your ears like most small bluetooth ones. Cons: – Nothing yet but I havn’t used them very much at this point.
– The only thing that seems a little off is the included 3.5 mm cable to use as wired. It’s flat, not very long, and seems like it might break easily. I would get my own cable if I wanted to use it wired. Overall Review: I would recommend them.

Pros: Pleasantly surprised by the quality of the ANC
Folds up for convenient storage
Sturdy, seems pretty reliable
Built-in volume control and skipping/call functionality buttons Cons: Does not come with a USB Bluetooth adapter – buyer beware for PCs without onboard Bluetooth!
Sound quality is middling, but this can be mitigated with an equalizer
Built-in microphone has poor quality Overall Review: I returned this product because it does not suit my needs, but I would still highly recommend it to people looking for a budget option for PC gaming, noise cancelling headphones for exercise, or wireless music. Value is tough to beat; you’ll be hard pressed to find another pair of headphones that is as functional as these are for the price.

Pros: Had great sound, noise canceling was quite good. Cons: Connections at earpiece just fell apart on both sides of the bracket. became unusable. Overall Review: I wish they would have put more thought into the construction of this unit, as I really liked them. Just too flimsy of plastic connecting it to other pieces.

Pros: I got the headphones a couple of days ago.
The main pro is its price, very cheap for its value.
For its price, it has a great sound.
It is user friendly, really easy to use and understand.
I liked the UX/UI.
Fits my head perfectly and comfortable. Cons: Noise canceling is not really good, but again, for its price its fine.
If you want a super duper ANC you should by a product according that. Overall Review: Overall, I would definitely but it again, very cost effective and fits my requirements as a regular consumer.
